Coserwation Tillage in California
Current estimates indicate that conservation tillage (CT) practices are used on less than 2％ of annual crop acreage in Californias Central Valley. Tillage management systems have changed relatively little since irrigation and cropping intensification began throughout this region more than 60 years ago. The University of California (UC) and the United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) CT Workgroup is a diverse group of UC, NRCS, farmer, private sector, environmental group and other public agency people that has provided wide-ranging services aimed at developing information on reduced tillage alternatives for Californias production valleys. In a short span of seven years, the Workgroup has grown to over 650 members and has conducted over 60 demonstration evaluations of CT systems. While CT is still quite new in California, a growing number of farmers has become increasingly interested in it for both economic and environmental reasons and are now pursuing a wide range of activities and approaches aimed at accelerating its adoption. Two crop production systems in which CT has been growing are dairy forage crop and tomato systems.
