Understanding on-farm soil health
Tim Bowles, Professor
Environmental Science, Policy and Management
Closed. This professor is continuing with Fall 2023 apprentices on this project; no new apprentices needed for Spring 2024.
Despite extensive efforts to measure on-farm soil conditions, the concept of soil health continues to be a murky concept across soil science, agriculture, and policy disciplines. However, soil health is critical to productive agriculture and long-term, whole-farm resilience. At present, most measurements of soil health on organic farms often involve observable or qualitative assessments, at best, and/or lack calibration to local climates. In addition, incorporation of farmer perceptions is also currently lacking. To address this gap, additional research on overall on-farm soil health metrics for farmers in regions with diverse microclimates like California is essential.
Our research will measure biophysical indicators of soil health on mixed-vegetable, diversified farms in Yolo County. We will complement this work with qualitative metrics, where we will determine farmer perceptions of soil health through semi-structured interviews. This study will further our understanding of the functional role of soil health on farms, incorporating existing farmer wisdom with quantified soil metrics.
Role: Students will be asked to work on ongoing lab work for the project. Soil measurements will include nutrient cycling and microbial activity. This project is an excellent opportunity for students interested in fine-tuning experience with lab work.
Qualifications: Interest in soil science, microbial ecology, and agroecology. Extreme precision and attention to detail. Interest in detail-oriented work. Previous lab experience is required.
Hours: 6-8 hrs
