Amador Soil Health Research and Education Project

A truck is spreading material on a field under a clear sky.

In partnership between ARCD, UCCE Central Sierra, and several Amador County agricultural producers, the Amador Soil Health Research & Education Project is studying the effects of a one-time compost application to annual rangelands. Specific metrics being studied include indicators of soil health, forage production and quality, and noxious weed abatement. 

The study began in Fall of 2019 when ½” of compost was applied to 5 rangeland properties in Amador County.
