Final Report for SW13-017
- descriptions of the farm’s soil, disease, and insect management practices
- aggregation and analysis of farm data (e.g. soil analyses, pest scouting and management records, rotation histories, yield records)
- identification of the farm’s soil and pest management successes and challenges
2) Farm System Analyses that focus on a specific topic (e.g. nutrient management, management of a specific pest), using data from one farm or multiple farms.
The FSDs and FSAs will be used by farmers, extension and other agricultural professionals, educators, students and researchers to:
- better understand how organic farmers manage soils, diseases, and insect pests
- identify which pests are successfully managed (and how), and which pests remain problematic and should be research priorities
- describe successes and challenges in organic soil and nutrient management
3) Engagement. The project engaged farmers, agricultural professionals, students, and researchers through presentations, field days, workshops, and courses throughout the course of the project.
- Persephone (OR)
- Wintergreen (OR)
- BioDesign (MT)
- Woodleaf (CA)
- Phil Foster Ranch (CA)
Another objective was to engage farmers, agricultural professionals and researchers with the information in the FSDs and FSAs so as to increase our collective understanding of what is working and what is not on experienced organic farms, and to identify critical research questions.
A fundamental goal of organic farming systems is to rely primarily on cultural and biological strategies for pest and soil management. Expert organic farmers manage soils and pests using a farm-specific toolbox of interrelated biological and cultural strategies and they avoid using pesticides (especially those with adverse effects on natural enemies) until all other options fail. However, there is little information available on farm-developed soil and pest management toolboxes and their efficacy. Therefore, it is difficult to determine if that fundamental goal of organic farming is being met on organic farms, and if so, how? The primary goal of this project was to address this question.
Farm System Descriptions and Analyses:
Project staff met with project farmers to collect farmer philosophy, experiences, and data sets:
• Data set 1: Farmer description of farm history, philosophy, markets, crops, systems management, record keeping
• Data set 2: Farmer-collected data (soils, crops, pests)
• Data set 3: On-farm research data sets (past research projects conducted on case farm, if any)
• Data set 4: Case study farmer’s knowledge and practices about systems soil/pest management strategies
Project staff then developed:
1)FARM SYSTEM DESCRIPTIONS (model structure below)
Farm System Overview
- About the farm
- Farm Philosophy
- Key Farm Design and Soil- and Habitat-Building Strategies
- Soil Management System Overview
- Disease Management System Overview
- Insect Management System Overview
Soil, Insect, and Disease System Descriptions
- Key Practices
- Integrating Practice and Research
- Figures and Tables
- References and Citations
- Additional Resources
2) FARM SYSTEM ANALYSES
Farm system analyses are in-depth analyses of the experiences and data of one or more farms related to specific topics, i.e. cabbage worms and nutrient management. Project staff aggregated and analyzed data from one or more farms and developed that information into an article including a discussion integrating research and practice.
Project staff and farmers engaged farmers, ag professionals, students and researchers through presentations, field days, workshops and courses.
This project was very ambitious and farm system description development has taken much longer than anticipated.. Early versions of the farm system description were long and project farmers and agricultural professionals could not learn from them. As the result, mid-way through the project, a more accessible system description structure was developed and all materials were revised to this new structure. The structure is intended to allow readers to access the information through multiple entry points. Readers wanting only an overview of a farm and its practices can read the farm system overview. Readers interested in management strategy details can read the farm soil, insect and/or disease system descriptions, and if very interested they can access the farm’s data in the figures and tables.
Extension agent: “This is the kind of real-world observation and lesson-drawing from that observation that should be at the heart of all organic production, presented in a way that will be accessible and comfortable for farmers. There are plenty of references for folks who want to explore further. The information itself is of great interest but the underlying philosophy and method used to move the farm forward are probably the greatest lesson here. I would definitely recommend this to our growers. The emphasis on reduced tillage and living mulches, and the ability of a living mulch to sequester and recycle N, certainly is of highest relevance and interest to organic producers, and the correlations between changes in soil fertility and other aspects of farm management will be of great interest. The sections on excessive buildup of NPK are particularly intriguing both for new producers who would give their right arm for that problem, and long-term producers who may be experiencing the same phenomenon. The possibility of weeds as habitat for beneficials is something that many producers have been working with and will be interested to see these results.”
Farmer: “This article describes in extensive detail a farm which I visited several times while it was in production. The vegetables produced were uniformly beautiful- particularly the peppers. What was most remarkable was the near complete absence of weeds. It was as though weeds were just not part of the biome. The surrounding land was basic range land, and in my experience, under different management, the field would have been full of annual or perennial weeds. It is certainly clear from the farm records that keeping the land covered is best for soil health and increasing organic matter”

Areas needing additional study
This project focused on soil, disease, and insect management. It would be useful to further develop the FSDs by adding additional sections addressing topics such as weed management and social, environmental, and economic sustainability.
