Final report for ONE21-407
Project Information
This project aimed to push the boundaries of organic farming by designing unique no-till crop rotations that could enhance soil health and resilience. We wanted to prove that with innovative practices, like planting diverse cover crops and using no-till methods, we can produce high-quality forage while minimizing soil disruption and improving farm sustainability. We ran into many challenges which are indicative of the challenges of farming in the northeast. The project can be summarized with the following assessment.
Uncontrollable challenges: growing season, weather & inherent soil types
Throughout the span of the project, many inherent and uncontrollable factors created challenges for successful implementation and desired outcomes. These systems are dependent on early cover crop planting to achieve sufficient crop biomass for weed suppression as well as relatively later corn planting that aligns with timing for effective cover crop termination with the roller crimper. Vermont’s short growing season can already be limiting for crop production, and providing timely windows for cover crop establishment was a challenge in the rotations. These already narrow windows were exacerbated due to weather and soil type. The heavy clay soils in Addison County are unforgiving in periods of dry or wet weather. Excessive precipitation in summer and fall of 2023 made field operations impossible and the farm was unable to turn over hay ground and seed a cover crop at the appropriate time. Additionally, in 2024 the farm planned to turn over hay ground and plant rye (similar plans to Field 2), but prolonged drought made it impossible to run over hay ground and seed a cover crop.
Flexibility is key
While advanced planning is crucial to implementation, the uncontrollable challenges underscored the need to be flexible and deviate from plans. Sufficient cover crop biomass is necessary to suppress weeds, and the timing of roller crimping is critical for effective termination. If conditions seem unfavorable for successful crop production, alternative management like tilling under the cover crop should be considered. For Field 1, the farm planted a new seeding instead of corn since the legume cover crop did not overwinter. In Fields 2 and 3, the farmer went through with planned rotations despite not having ideal roller crimping conditions. While this was beneficial within the grant to evaluate the effectiveness of implementing the system despite ideal conditions, it does highlight the importance of evaluating the field in the spring and pivoting to a new plan as appropriate. With these alternative plans it was also important to consider how the shift in management may affect nutrient, pest, crop or other management decisions. For example, early season nitrogen deficiencies were observed after tilling under a cover crop when there was insufficient biomass to roll and crimp.
Cover crops: Setting yourself up for success
The success of the cover crop often influenced crop production in these rotations. In addition to timely planting, manure application and termination, cover crop species selection is also important. Challenges were encountered on both Field 1 and Field 2 due to cover crop variety selection, seed source and management. In these systems, desirable traits include overwintering, early maturing, high biomass, later planting dates, and lower lodging, and perhaps with greater attention to cover crop breeding, there will be more opportunities for successful implementation of organic no-till systems in the future. However, accessing these seed sources can be challenging for Vermont farmers due to higher costs and limited local access, so this may be a barrier to implementation. If conditions do not allow for timely cover crop planting that will achieve sufficient spring biomass, it may not be worth it to spend more for these desirable traits.
Summer Annuals: Opportunity for renovation
The sorghum sudangrass and winter pea mix (Field 1) was very valuable in the rotation. Not only did it provide high yielding and high-quality forage, but brought livestock on the annual cropland through grazing, stimulated the soil biology, and created a sufficient window in late summer to establish a legume cover crop. Kemp was very pleased with the results of including summer annuals in his rotations and hopes to continue to integrate them in his rotations. Fencing in annual cropland on the farm is one barrier to replicating this part of the rotation, but the farm expressed great interest in better integrating annual cropland and pastures and using summer annuals as an opportunity to renovate degraded pastures.
Outreach
The outreach efforts of this project initially focused on leveraging local networks and farmer-led organizations like the Champlain Valley Farmer Coalition to disseminate information. Plans included hosting on-farm demonstrations, field days, and presentations at regional events like the No-Till and Cover Crop Symposium, but these were significantly impacted by the challenges in implementing the no-till system. Despite these hurdles, some outreach was achieved through a farmer panel at the No Till Cover Crop Conference and a Soil Health Field Day at Mountain Meadows Farm, where the project's challenges and lessons were shared with local farmers and technical service providers.
- This project seeks to demonstrate organic no-till (OGNT) forage crop rotations on a working livestock farm in Vermont. Our hope is to not only demonstrate it is possible, something we have not seen yet in an organic forage system, but to also give farmers a reference point for the options they have available to utilize no-till practices in organic systems.
- This project seeks to track all facets of the OGNT system. This will include data on field operations and equipment, inputs, yields, forage quality and cost of production. Because these OGNT crop rotations will be designed to be adaptable for best success, we will also document important decision points along the way. Why were plans changed, how/why were decisions made, were results as intended? Having the farm’s Livestock Nutritionist on the project will allow us to also track how these innovate crop rotations fit into his feeding program and impact purchased grain.
- This project seeks to share and transfer knowledge to producers, both organic and conventional. This will be accomplished through existing outreach channels that include in-person field days, presentations at conferences and workshops, social media posts, newsletter articles and blog posts, and a published case study.
We have made good progress in Vermont with conventional forage crop producers adopting conservation cropping systems that involve cover crops and no-till practices to build soil health and protect water quality. However, certified organic producers have not had the same success, as they struggle with rotating between annual and perennial forage crops and maintaining proper weed control without tillage. This is challenging, as most organic producers are very motivated to build soil health and increase the sustainability of their operations. In addition to reducing erosion, decreasing nutrient runoff, and improving soil health, we also believe that organic no-till cropping systems can decrease labor and some production costs. We aim to highlight the opportunity for these systems to also provide an alternative for conventional producers hoping to reduce their synthetic inputs. This project would utilize the methods we have used with conventional producers to adopt cover cropping and no-till practices with very good success. We will demonstrate the techniques and systems on an operating farm. We will document and share our results and the steps we took along the way. We are taking into to account the whole farm picture – how it impacts crop production, farm operations and forage quality for the livestock. We are working with a respected producer who is excited to share the project with his peers and is the driving force behind the project, with a very vested interest.
Organic no-till grain rotations have been studied in the northeast through the Rodale Institute’s work, Cornell’s Sustainable Cropping Systems Lab (M. Ryan), Penn State University and the USDA Beltsville ARS. However, most of these projects focus on grain systems, tend to be situated in the mid-Atlantic portions of the northeast, and are still finding challenges to adopting these systems. Very little, if any, of this work has been done in the context of organic forage crop production. We believe Vermont and other northeast livestock producers have a unique situation that allows them to troubleshoot and respond to these challenges with the flexibility that forage crop production and grazing brings to the system. Dairy and beef producers in Vermont have not really been able to see for themselves the potential for how an organic no-till system could work here. Every year at our annual No-Till and Cover Crop Symposium hosted by UVM Extension, we hear from attendees that they would like to learn more about these practices in organic systems. This project would be the first of its kind here in Vermont.
By providing examples of successful organic no-till forage crop rotations to both organic and conventional producers, we believe we can reduce two potential environmental impacts from the production of forage crops. Reducing tillage in organic systems, which will reduce erosion and nutrient runoff and protect soil biology. Reducing the use of herbicide in conventional no-till systems and associated impacts from these. These benefits are already proven, so this project will focus on the ‘how’ of actually implementing the organic no-till forage crop system.

Research
Design and Implementation of Innovative OGNT Crop Rotations
The first part of this project involves the design and implementation of three very unique crop rotations. Some of this work has already been done in preparation for this project proposal. The project team has already reviewed the initial crop rotation plan (see attached). The design is as follows:
FIELD ONE:
PLAN: Currently in cover crop. Summer annual forage mixture (Sorghum x Sudangrass and forage pea) will be planted in May/June and harvested in late summer. After harvest, we will plant legume cover crop mix (vetch, clover, pea) in August. This legume cover crop will be rolled and crimped the following spring (2022) while planting corn silage. Corn silage will be harvested in late September and followed with a winter cereal grain cover crop. This will likely be followed the next spring with a new perennial hay/pasture seeding.
2021 Crop Season:
This field was planted to a Sorghum-Sudangrass/pea/soybean mixture in mid June. After a good catch and growth on the crop, the farmer decided to put up a fence and graze the crop. He moved cattle in there the first week of August and moved through the 20+ acres in ~5 days, splitting the field into 4 paddocks. UVM Extension staff collected yield measurements and forage samples and took pictures (Figure 1).
The farmer then followed the cattle with a slightly adjusted winter cover crop mixture that consisted of hairy vetch, winter pea, tillage radish and oats planted with his John Deere no-till grain drill. Roughly 5 weeks later on September 21st, the farmer grazed the summer annual mix again after really good subsequent growth. He was careful not to overstock the field and didn't break it up into smaller paddocks and moved the animals through quickly as to not damage the winter cover crop established in the understory.
2022 Crop Season:
The 2022 crop season was challenging due to poor cover crop establishment and overwintering. Cover crop establishment was hindered by dry conditions in fall 2021, followed by high precipitation prior to freeze. Cover crops did not overwinter and without any regrowth to rollercrimp, there was no weed protection for the 2022 crop. Since having sufficient cover crop residue is essential to mitigate weed growth for organic no-till corn, the farmer recognized the need to adjust the crop plans. In May 2022, the farmer seeded the field back into alfalfa-grass mixture rather than no-tilling corn.
FIELD TWO;
PLAN: Currently in hay. This first year we will take two cuts of hay during the season. In August we will forego a third cut of hay and instead no-till plant a heavy seeding rate of winter rye. Next spring (2022) we will no-till plant soybeans on 15-inch rows. Roughly a month later we will roll and crimp the winter rye cover crop. Depending on performance, we will either harvest the beans as forage or let them go to grain. This harvest decision will determine what type of cover crop gets planted, and the subsequent cash crop.
2021 Crop Season:
After assessing field conditions, we decided to keep this same plan but switch field locations. The original field had better alfalfa growth than expected, so we chose a nearby field that was mostly grass. Otherwise we stuck to the plan. In mid September 2021, the farmer chopped the hay off and spread manure. He then chose half the field to do disc harrow the hay crop and left the other half in growing sod, then no-till drilled a high rate of winter rye into both sides of the field. In the fall, the no-till side did not seem to have great growth of the winter rye, while the tilled side had good establishment.
2022 Crop Season:
Accumulating sufficient rye biomass to provide weed protection to the 2022 crop was a challenge. After rye was established in fall 2021, the farmer applied manure at a rate of 4,500 gal/ac. We believe that the rye was too young at the time of the application and the manure stunted rye growth. Additionally, the rye that was seeded on the no-till side of the field, could not compete with the existing grass crop. Both of these factors contributed to a thin stand of rye in spring 2022. In accordance with the field plan, the farmer no-till planted soybeans at 15" row spacing, and rolled and crimped what rye was there (Figure 2.).
The weed pressure was so severe that the field was unharvestable. Given the severe weed pressure, we had to deviate from the crop plans. The farmer moldboard plowed the field in fall 2022 and will seed the field into alfalfa grass in spring 2023 to control weed pressure.
2023 Crop Season
This field was seeded down to Alfalfa in the spring of 2023 and it has been productive in that rotation to date.
FIELD THREE:
PLAN: Currently in cover crop. We will seed alfalfa with a small grain nurse crop this spring (2021). We will harvest the alfalfa for two seasons. The third year (2023), we will no-till plant corn silage and roll and crimp the alfalfa to terminate.
2021 Crop Season:
The farm was able to seed alfalfa with an oat nurse crop in May 2021. The alfalfa established well, and one hay cutting was harvested which consisted mostly of the oat nurse crop. We expect to harvest the alfalfa in 2022 with no major issues.
2022 Crop Season:
2021 weather conditions resulted in poor germination and winter kill of the alfalfa (Figure 3.)
. In the spring 2022, the farmer no-till planted alfalfa into the existing stand and harvested the alfalfa throughout the crop season.
2023 Crop Season:
Due to winter kill of the alfalfa, in spring 2023 this field was approximately 50% alfalfa and 50% grass species. With the amount of grass in the field, there was concern over the efficacy of rollercrimping to terminate the hay field. To experiment, we rollercrimped and no till planted corn in one strip of the field (12-rows corn) to evaluate if we could establish the corn crop. As expected, the rollercrimping did not terminate the grasses or alfalfa and we saw poor germination of the corn field. Since the hay stand was still good, the field was harvested as hay for the season.
2023 Update:
After a couple of challenging seasons to successfully implement the proposed rotations for an organic no-till forage system, we spent spring and summer of 2023 planning for the upcoming season. We planned on two approaches we would try: no till planting corn into rolled rye/vetch and no till planting soybean into rolled rye.
Field 1: vetch/rye to corn
In a previous season when we planted vetch and other legume cover crops, the cover crops did not overwinter and we had insufficient biomass to suppress weeds in a rollercrimped system. We conferred with Dr. Moore (Professor at Cornell and project manager for the Legume Cover Crop Breeding (LCCB) network,), Dr. Kucek (who leads vetch breeding efforts with ARS) and University of Wisconsin- Madison’s Silva lab for recommendations of suitable varieties of vetch. While Dr. Moore and Dr. Kucek are still in the process of breeding new legume cover crop varieties, some recommendations for currently available varieties included VNS seed from Albert Lea Seed, VNS from Minnesota Buckwheat Growers, the new variety ‘Minnesota Vinter’, and ‘AU Merit’. In addition, to better align ideal termination time of vetch and rye, seeding the vetch with an early maturing variety like Aroostook would be beneficial. We plan to drill the rye/vetch mixture by the end of August at the latest, in order to get the best establishment, biomass production and overwintering potential, all of which are necessary for sufficient spring biomass.
Field 2: rye to soybean
For this field, we planned on using a specific variety of rye rather than variety not specified (VNS). Though VNS rye is more common and accessible in Vermont, we recognized that planting a specific variety will help us have more consistency in this system and allow us to select for desirable traits like early maturing, high biomass production, and less likely to experience lodging. Potential varieties that we selected were Aroostook and ND Gardener. We planned to seed rye at a rate of 150 lb/ac in September.
2023 CROP SEASON:
The weather during summer and fall of 2023 proved very challenging to implement these plans due to excessive precipitation and saturated soils. At Mountain Meadows, there was 20 inches of precipitation from July through August, with continued precipitation and saturated conditions throughout the fall. These conditions were exacerbated by the farm's heavy clay soils, which remained saturated for the entirety of the growing season. It was very challenging for any field operations, including those necessary to implement the plans described above.
Field 1: vetch/rye to corn
The heavy precipitation and saturated conditions made it impossible for an field operations to occur throughout the summer. Knowing that the vetch needed to be seeded by the end of August to be effective, we were unable to implement these plans. The farmer remains interested in experimenting with legume cover crop varieties if weather conditions prove favorable in future years.
Field 2: rye to soybean
These conditions also made it challenging to get on the field throughout the fall, as clay soils remained saturated despite brief windows without rainfall. Though it was past ideal timing, field operations were possible in October. We turned over a sod field, applied bedpack manure, and seeded rye at 150 lb/ac on October 17, 2023. Due to limitations of seed availability, the Aroostook rye variety was selected. We will monitor biomass production in the spring to determine if we have sufficient biomass to roll and plant no till soybean into this field.
Note: All crop rotations are subject to modification depending on field conditions and how crops respond to planting, cover crop termination, weather and other conditions. In order to ensure success, we maintained some flexibility to adapt to changing conditions and availability of seed, grazing animals, harvest equipment etc.. Our hope is that the diversity of crops and cover crops will lend themselves to flexibility when it comes to timing of planting and harvest to ensure the desired outcomes of reduced and eliminated tillage and high quality forage crop production.
Though weather has been a recurring challenge in implementing this no-till organic forage system, we continue to learn and plan in hopes of successful implementation. The farmer remains very motivated to continue to implement this system when conditions are favorable.
Collecting Data
PLAN: All fields will be soil sampled annually. We will send soil tests to the University of Maine for basic soil chemistry analysis. This will help us make accurate nutrient and soil amendment applications for the desired crops. Manure samples will be collected as spread to account for total nutrients applied in manure on each field. These will also be sent to the University of Maine. Any commercial amendments will use the analysis provided by the manufacturer for nutrient content and availability.
2021 & 2022 Crop Season:
Soil samples were taken for all fields in either the fall or spring ahead of planting in 2021, and in summer 2022. Soils were analyzed for basic soil chemistry to help inform nutrient and soil amendment applications.
Forage crops were sampled for yield and quality, either at harvest by the farmer or just prior to harvest by UVM Extension staff. For hay crops, the farmer collected yield data at each cutting. Yields for field crops with wider spacing (sorghum sudangrass) was measured in the field by UVM Extension staff, prior to grazing. Measurements were taken from multiple 1/1000th of an acre plots throughout the field and weighed on a tripod mounted field scale. Representative stalks were run through a chipper, and composite chipped samples were dried to determine percent dry matter. All final dried composite samples were ground to 2mm and submitted to Rock River Labs for NIR analysis for forage quality including parameters for protein and amino acids, carbohydrates, minerals and ash, fermentation products, digestibility, energy and anti-nutrients (molds, yeasts, vomitoxins, etc.). In addition, the nutritionist will sample forages from bunker silo storage before feeding to be sent to the same lab. We have chosen Rock River Labs, as that is the current lab Brian and his nutritionist use, and we want our samples to be comparable to historic forage quality information and be able to be used when balancing rations during the project period.
All field operations were recorded. This includes any planting (date, rate, depth, machinery used, etc.), cover crop termination (roll/crimp, mow, graze, etc.), harvest (dates, times, yield as above, growth stage, type), manure and soil amendment applications (time, rate, nutrient composition). In additions fields were photographed during multiple stages of the crop rotations.
Brian is tracking labor and equipment time on all field operations. In addition, costs of all inputs were tracked. Any changes made to the livestock ration as a result of a new forage in the rotation (sorghum/pea, soybean, etc.) or related to yield or quality will be assessed with the help of the Livestock Nutritionist.
General weather as it pertains to crop production by logging rainfall, growing degree days and temperatures was tracked throughout the season using the closest weather station (KVTWHITI13) in the Weather Underground Network. In early summer of 2022 we placed a Davis instruments weather station (Vantage Vue) at the farm. It is on the Weather Underground Network station ID is KVTSUDBU1.
2021 Cropping Season:
- Baseline soil tests and field assessments were collected just prior to the project starting.
- In August, we collected yield and quality data just prior to grazing of the summer annual forages planted in Field 1.
- We also are keeping track of field operations, inputs, and farmer impressions.
Overall this first cropping season went very well. Brian Kemp, the Farmer/Cooperator, is committed and engaged in the project. Having Rick Clark as a consultant has been helpful to make decisions on the fly, mid-season, when decisions and adaptations need to happen to ensure success. We really only had one harvestable crop (by design) this first cropping season, the forage sorghum/sudangrass/soybean/field pea combination. This turned out very well, and Brian's herd was able to graze it twice - once in August and once in September. The winter cover crop was established between the two grazings, and we hope to see good spring growth. Brian even invested in perimeter fencing to facilitate grazing, showing his 'all in' approach to making this organic, no-till system work. Next season will be where the bulk of the work and critical decision-making will come into play. There will be two fields were true no-till crop planting will occur without the use of herbicides. With the help of UVM Extension project staff, Brian was successful in receiving grant funding to purchase a cover crop roller-crimper. He is also working with project staff (UVM Extension and Rick Clark), to ensure his corn planter and grain drill are equipped to plant through residue in this new system. The key in 2022 will be flexibility, quick decision-making and good communication between the project team.
2022 Cropping Season:
- Soil tests were taken in summer 2022
- Field assessments and photos were taken in May and September of 2022
- Yield and forage quality data collected by the farmer and nutritionist throughout
- A Davis weather station was placed on the farm in early summer of 2022 to better capture weather data
The 2022 crop season demonstrated the challenges of making a no-till organic forage cropping system succeed and the need for flexibility in a crop rotation. In 2022, the success of any crops was dependent on fall 2021 and weather. In fall 2021, there were drought conditions, followed by high precipitation prior to freezing. This hindered cover crop establishment and growth in fields 1 and 2, and the alfalfa in field 3.
2023 Cropping Season:
- Field assessments and photos were taken in June and October of 2023
- Yield and forage quality data collected by the farmer and nutritionist throughout; but thus far we have not had successful no-till crop following a roller crimped cover
- We continue to collect weather data from the Davis weather station
The 2023 season again proved challenging to implement this system. Going into the 2023 crop season, we only had plans to no till into the alfalfa field with corn. Unfortunately, having about 50% of the field in grass species made successful termination with the roller-crimper impossible. We were grateful for the no cost extension and spent the season developing plans for the 2024 cropping season. Unfortunately, the excessive rainfall and saturated conditions this year prevented any field operations from occurring, including those for successful cover crop establishment.
2024 Cropping Season:
The 2024 cropping season was again challenging with the rain fall in the spring heading into summer. At this point in the project all the project fields have been seeded down to alfalfa. The highly variable weather patterns throughout the duration of this project has made the establishment of cover crops very difficult. This drives the subsequent decision making with regard to weed suppression and cash crop establishment. For the fields involved with this project growing perennial forages to try to make them productive and battle the weed pressure makes the most sense economically and from a resiliency perspective.
2021 Cropping Season:
As this is the very beginning of this project, we do not have any conclusions currently. The data for the field assessments for the cover crops planted in 2021 and the soil sampling results are still being compiled and will be made available in future reports. We will put together a table of with the pre planting cover crop, weed assessment, and nutrient usage in the spring. The work done in 2021 was done to prepare the fields for the implementation of the project in 2022. Pictures and details are much more relevant for the 2022 growing season when all case study and field work will be implemented.
2022 Cropping Season
The winter and spring of 2022 were very difficult for this project. Between the lack of biomass on Field 1, the weed pressure and lack of a good cover crop stand on field 2, and the poor catch of alfalfa in field 3 the opportunity to plant corn was in accordance to this project were thwarted. However, we were able to get a solid stand of cover crops planted on a fourth field and should be able to plant corn next spring on field 3 and field four. The highly irregular weather patterns we have experienced since the implementation of this project points to the challenges associated with these types of practices. The farmer is still actively engaged with the project and we have had the flexibility to attempt a successful planting of corn in 2023.
2023 Cropping Season
After an incredibly challenging cropping season, we continue to learn the importance of flexibility in implementing a no till organic forage system and patience for when conditions may be favorable. This past year we connected with others who are experimenting with similar rotations, and learned more about cover crop variety selection, which will be incredibly important in this system. In addition, as there is greater investment in breeding legume cover crop varieties, implementing this system may become more feasible. The farmer is still actively engaged with the project, despite the challenges we've faced this far, and would be interested in continuing to work towards a no-till organic forage system.
2024 Cropping Season
The timing of this project coincided with some of the most volatile weather the state of Vermont has seen in decades. Because of this and the requirement that soil conditions be suitable for planting and other field operations during critical periods of the growing season this project faced significant challenges. Currently all the project fields are in perennial forage which was not the original goal of the project but the weather and economic situation warranted that is was the best management strategy for these fields.
Conclusions
The goals this project were lofty and the farmer/collaborator was fully vested in making this no-till organic system work. As a result of the struggles we had some key lessons were learned. First there were significant uncontrollable challenges with this particular project. The weather and the inherent soil types at the project location (extremely wet, and heavy clay soils) limited our options very quickly. The no-till system is robust once the soils become not addicted to tillage. A combination of the wet soil conditions and clay that was not aggregated well (due to previous tillage operations) resulted in poor establishment of the the cover crops. This created weed pressure in the organic row crop system which resulted in crop failures. It is important to remain flexible in the implementation of these kinds of systems. For this project we were limited to number of fields and we may have had better results if we could have moved the project to different locations on the farm with lighter soils and better internal drainage. Cover crop selection and establishment is the lynch pin for these systems. Having the proper weather for establishment and making sure you plant the cover crops early enough for good establishment will determine if there is a chance to have adequate biomass the following spring for the no-till roller crimp cash crop planting operation. For this project the weather prevented this from happening and the cash crops were no successfully established due to weed pressure resulting from insignificant biomass to suppress them. Due to the degree of failure in the crops, the farmer and nutritionist did not collect yield and quality data which was part of the original goals of this project. There was also nutrient deficiencies (nitrogen) in the areas of the field with inadequate cover crop biomass. One positive outcome of this project was that the farmer utilized summer annuals (sudangrass and winter peas) after the crop failures and they provided high-yielding and high-quality forage for the animals.
Education & Outreach Activities and Participation Summary
Participation Summary:
PLAN: As an agronomic Extension outreach program, the Champlain Valley Crop, Soil and Pasture team has developed a robust network of farmers, agriculture businesses, agency staff, service providers, policy makers and other stakeholders. In addition, we have close ties to the Champlain Valley Farmer Coalition (CVFC), a farmer-led conservation organization who also has a similar mission and outreach network of farmers and stakeholders. Our partnering farmer on this project, Brian Kemp, serves on the President of CVFC. Between the two organizations, we have networks of roughly 900 plus individuals, about half of which are farmers. Both Extension and CVFC have websites, social media accounts, email contact lists and physical mailing lists. In addition, we often leverage our broader Extension outreach networks and those of our sister programs within Extension.
We will use a proven outreach approach, which is based on utilizing respected, innovative and motivated local producers to try new practices and share their results and experiences with other growers. This in conjunction with tracking results and a focused outreach plan has resulted in good practice adoption and transfer of knowledge. Brian Kemp is the perfect fit to do that for this project. He has solid footing in both the conventional and organic farming arenas in Vermont. He is a detail-oriented manager that keeps good records and has an established relationship with the project team.
We will target our outreach to farmers in several ways. We will hold field meetings at Brian’s farm to showcase results of this project. We find that farmers like to see for themselves how practices look on the ground and ask questions of the producer showcasing them. We expect between 20 and 30 farmers to attend in-person field days, which we will do at least two of for this project. In addition, Rick Clark will give a presentation in conjunction with one of the field meetings. We would expect more farmers (50) to attend that event. We will share project results at the annual No-Till and Cover Crop Symposium (NTCC). That event draws around 100 regional farmers (200 over two years). The published case study will also be targeted towards farmers, and will be distributed digitally and in print to farmers through directed mailings, emails and events. We will print and distribute 300 copies of the case study and track links to the digital version.
In addition to farmers, the same approaches will be used to target agricultural businesses, agency/non-profit staff who assist producers with practice adoption, policy makers and the public. We find that these audiences often respond better to digital communications and as such often access our email newsletters, blog posts, social media posts. We can track those through email and blog ‘clicks’, social media metrics and also through attendance at events. We would expect 75 of these stakeholders to attend the NTCC each year (150 over two years), and they comprise roughly half of our digital mailing list (~450 individuals). We would also expect 5-10 at each field meeting.
2021 Crop Season:
During the 2021 crop season we did not do any formal outreach or education activities. As the first year of the project, we were focused on getting the fields and rotations established, preliminary data collected and the project team working together. We will use data, photos, etc in future outreach/education efforts related to this project.
2022 Crop Season:
During the 2022 season there was no reason to hold a field day as the three fields this project was being carried out on had nothing of interest to demonstrate to stakeholders. Our goal is to have a successful spring planting in 2023 and hold a field day in July to promote and present the opportunities and challenges of this approach to growing corn in this region.
2023 Crop Season:
As we continue to struggle with successful implementation of this system, this has hindered our plans for outreach and education since we haven't had successful trials or good data to showcase. If the rye we seeded in the fall 2023 is successfully established and we will be able to rollercrimp, we will hold a field in June/July 2024 to showcase the results. We also plan to develop a write up of the challenges encountered throughout the project and key lessons that may support other farmers.
2024 Crop Season
Brian Kemp presented in a farmer panel on no-till forages at the No Till Cover Crop Conference, February 2024 in Burlington Vermont. There were 159 farmers and technical service providers at that meeting.
There was a Soil Health Field Day hosted at Mountain Meadows Farm to highlight soil health practices and on farm challenges and progress of the SARE grant. Attendees totaled 20 mostly local technical service providers.
Learning Outcomes
Innovative and diverse crop rotations
Reduced and no-till in organic systems
Equipment and approaches needed for alternative crops and tillage types
New crop and cover crop types/species being planted
Project Outcomes
So far this project is off to a really great start. The farmer cooperator (Brian Kemp) dove all in and followed the crop plan almost exactly, making changes only for seed availability and timing to match weather and field conditions. He was able to get a successful crop of sorghum-sudangrass for the first time and even built permanent fence around a field that had not been grazed in the past in order to facilitate grazing this field. While we are only in the beginning of this project, it is already proven to be successful in getting the producer and the entire project team to think outside the box and try something new with good success. Next crop season will be where the rubber meets the road, when we start no-tilling more conventional crops like corn and soybeans. With assistance from UVM Extension staff, the farmer applied for and received a grant from the Vermont Agency of Agriculture's Capital Equipment Assistance Program (CEAP) to purchase a roller-crimper to use in conjunction with this project.
This project taught us that while the vision of no-till organic systems is promising, the reality on the ground can be fraught with challenges, especially with Vermont's unpredictable weather patterns. We've learned the importance of flexibility, patience, and the right cover crop selection for successful implementation. Despite not achieving all our initial goals, we've gathered invaluable insights on soil health, crop resilience, and the need for adaptive management in organic farming.
Reflecting on this project, it's clear that we encountered significant hurdles, particularly with the weather, which didn't favor the establishment of cover crops on these heavy, clay soils. Our original methodology aimed at pioneering a no-till organic forage system through innovative crop rotations, but the conditions we faced underscored the need for adaptive strategies. If I were to do this again, I'd emphasize starting with fields that have lighter, better-draining soils, or at least ensure we have the flexibility to shift operations to more suitable parts of the farm if conditions aren't right. We'd also focus more on selecting and breeding cover crop varieties that tolerate wetter conditions or germinate in less than ideal circumstances. Perhaps most crucially, we'd advocate for a more gradual transition to no-till, allowing time for soil structure to adapt, maybe even incorporating some light tillage initially to manage weeds and cover crop establishment better. This project, while challenging, has been a profound learning experience, reinforcing the importance of resilience, adaptability, and patience in our quest to enhance soil health and farm sustainability.
