Research Project: Quantifying Dynamic Soil Properties for Soil health in the Central Valley of California

Location: Water Management Research

Project Number: 2034-13000-013-008-A
Project Type: Cooperative Agreement

Start Date: Jan 1, 2023
End Date: Jul 31, 2025

Evaluate soil health metrics in cover cropped vineyards for soil beneath vines and beneath cool-season cover crops planted in interrow alleys. (ii) Compare soil health metrics determined for California Central Valley soils to those derived from a cross-continental US study.

California State University, Fresno (CSUF) student will collect soil samples over two years to monitor soil structural stability, general microbial activity, carbon food source, bioavailable nitrogen, microbial biomass, soil respiration, and soil organic carbon. All analyses will be conducted by the CSUF student at the USDA-ARS research station in Parlier, CA with training from USDA staff. Student will also work at CSUF to determine soil salinity measurements for Five Pints field samples. All analyses will be conducted using standardized protocols provided by NRCS to best facilitate cross-site comparisons.
