Ten farmers produce and sell 9,000 pounds of specialty mushrooms over 30 weeks, generating $108,000 in
In a previous USDA-SARE-sponsored national survey of shiitake growers, 89% of respondents indicated that demand consistently exceeded supply in their region. A 2015 Chatham University study interviewed 23 Northeastern buyers who reported needing 7,075 pounds of shiitake annually to fulfill customer demand; only 2,060 pounds (29% of demand) of locally-produced shiitakes were available for purchase. Despite this demand, only 229 farmers reported growing specialty mushrooms, and both the number of growers and the production rates have declined over the past three seasons. United States per capita consumption of all mushroom species was only 2.7 pounds in 1978 but by 2014 averaged 4 pounds per capita. The market for mushroom consumption has steadily increased over the past decades and is projected to continue to grow. Farmers are unable to access this market because of a lack of training, resources, and experts to consult. Small-diversified vegetable/livestock farms, beginning farms, and urban farms are prime candidates for specialty mushroom cultivation. Over 75% of farmers who participated in a survey conducted by the project team responded that they would benefit from participating in a project gathering data on methods of mushroom
In order to propel a new generation of specialty mushroom growers, this grant will compile data on specialty mushroom production. We will support a cohort of start-up growers to model a range of commercial operations in exchange for data on start-up costs, labor, and other key considerations. The comparative data from various scenarios will be compiled and form the basis of outreach materials and enterprise budgets. We will focus efforts on three systems of cultivation:
Oyster mushroom cultivation on straw.
Specialty mushroom production on ready-to-fruit blocks indoors.
Specialty mushroom production on ready-to-fruit blocks outdoors.
After developing a guidebook and video resources, project educators will engage 300 growers in two-hour workshops. A subset of interested growers will attend follow-up online sessions. These attendees can apply for ongoing mentoring as they develop and implement a business plan. Ten growers will be accepted for intensive support from the project team in exchange for keeping track of labor and economic data while starting and operating their enterprise. Growers will offer a range of scenarios that will be described in case studies and enterprise budgets, which will be published along with a finalized cultivation manual. All materials will be available indefinitely online.
Specialty mushroom production can be profitable in several scenarios, but important cost/benefit analysis for a variety of approaches is critical to grower success.
This research is targeted towards farmers interested in mushroom cultivation. It is for established farmers who
are looking to diversify crops, increase revenue, or use underutilized spaces. It is also for beginning farmers
looking for a high-value crop that requires low space and capital investments. As demonstrated through this
application, the research and information available to this population is currently inadequate to meet the rising
demand for local mushrooms.
This research will be done by grant participants with the guidance, input, and support of the project team.
Growers who submit a plan will decide whether to inoculate their own substrate or purchase ready-to-fruit blocks.
The information presented through the first four milestones will enable growers to make this decision with the
help of the project team.
The data collected will provide a comparison of time and earning potential between growers involved in the entire
production cycle compared to growers who purchase ready-to-fruit blocks. The data will also allow for
comparison between indoor and outdoor growers. Grant participants will agree to collect a range of data through
the 30-week growing season in exchange for technical and material support.
Growers will be provided excel templates and printed sheets for data collection. These sheets will be developed
by the project team for growers to record weekly expenses, sales, harvest, and labor hours. More established
infrastructure and utility needs will be recorded monthly.
All data will be submitted monthly to an online database. The research team will check in with each grower once
a month to answer any questions on data collection and ensure the farmers submit data for that month. The
sample population will be 10 farmers, each cultivating an average of 30 pounds per week. This will ensure a
range of scenarios and methods of cultivation from which to collect and analyze data.
Data collection and Analysis:
The aim of collecting this data is to give potential mushroom farmers clarity on the variety of growing methods
available and the drawbacks and benefits to each. To this end, grant participants will collect weekly data on the
All labor hours to inoculate, monitor, initiate, sell and harvest mushrooms;
Any costs for materials including spawn, substrate, or blocks;
Weight of harvested mushrooms;
Revenue from fresh mushroom sales;
Percent contamination of substrates, if any;
Any observational data that will be useful in reporting successes and failures.
Participants will also collect the following data on a monthly basis:
Cost of utilities associated with mushroom production;
Amount of space dedicated to inoculation, incubation, fruiting, storage;
Infrastructure needed for production.
Statistical analysis of the harvest data will generate a p-value to determine if the yields from all farms are
significantly different depending on the method of cultivation. Economic data will be compiled and presented as
both average time and material costs. An analysis of the cost-benefit ratio for each method will be developed.
Each enterprise will be individually analyzed and total averages will be calculated. Several farms will be
highlighted as case studies. The project team will conduct visits to each farm in order to take photos and notes
about the infrastructure, size, and methods of the farm.
We used established mushroom listservs and groups to spread the word about this project. Cornell, UMass,
and other extension departments helped recruit farmers through their newsletters. Recruitment was also done
through social media outreach. The first two specialty mushroom cultivation guidebooks were published in Oct 2019 to further recruit and offer clarity on methods of cultivation.
a. Mushroom Life Cycle. Understanding the life cycle as it pertains to cultivation.
b.Systems of commercial mushroom cultivation. Three different options for materials and methods of specialty
c.Building a Growing Space. The parameters needed for proper mushroom formation and how to create them.
d.Inoculation Procedures. Familiarity with past research and methods to grow oyster mycelium.
e.Managing contamination and pests. How to manage issues with inoculation and fruiting of specialty
f.Harvest and Storage. When to harvest, quality control, and post-harvest storage.
g.Selling and Marketing. Pricing, markets, and methods of selling mushrooms.
h.Building a Viable Enterprise. Incorporating mushroom cultivation into a farm business, cost-benefit analysis.
