CT production at San Joaquin Valley tomato farms
Two commercial variations of the general CT and cover crop systems that are described here were recently featured as part of the San Joaquin Valley Conservation Tillage 2005 conference farm tours that were held in June.

visited uses winter cover crops and a spring strip tillage operation to mix cover crops and
