Farmland diversification in Yolo County: Understanding organic farm diversity across social, ecological, and spatial scales
Under guidance from Professor Bowles and his graduate student (Ansel Klein), I will assist in quantifying soil health based on nutrient cycling and microbial activity metrics. I will assist in visiting 15 organic farms and subsequent field sampling of two fields per farm, taking soil samples using an auger and placing them in labelled bags to be brought to the lab for analysis. Specific field and lab measurements will include: potentially mineralizable N, POXC, total organic C and N, and microbial biomass C and N. The results will be analyzed in conjunction with farmer interviews to determine linkages between farmer knowledge of soil health and measurable indicators.
