Despite the growing interest in soil health in many parts of the country, the notion hasn't captured the imagination of most farmers in California. The Golden State's lackluster attention to soil care is likely due to “phenomenal yield increases over the past several decades, the sheer diversity of cropping systems, and widespread perception that California's environment and crop production mix doesn't lend itself to soil health improvements,” said Jeff Mitchell, UC Cooperative Extension agronomy specialist.

A series of farm visits this summer in the Central Valley prove this rationale wrong, Mitchell said. The farm visits were sponsored by the UC Conservation Agriculture Systems Innovation Center (CASI), USDA's Natural Resources Conservation Service and the California Association of Resource Conservation Districts. The farm visits showcased the soil health goals and experiences of six farmers who are familiar with soil care principles across a wide range of local cropping contexts.

The series of visits demonstrated the use of no-till and minimum tillage farming, cover cropping, enhancing the diversity of above-ground species and underground soil biology, surface residue preservation, and compost applications. Read more.
