A one-page UC Cooperative Extension handout authored by UCCE Advisor Ellie Andrews, presenting 2023 soil fertility, microbial, and structural assessment data from Yagi Sisters Farm with permission from Reyna Yagi. Includes results from Dellavalle Labs (soil fertility), Ward Labs (microbial biomass and diversity index), bulk density measurements, and water infiltration rates across multiple farm blocks compared to an uncultivated reference site — demonstrating notably higher organic matter, microbial biomass, and water infiltration in cultivated areas.
