Conservation Tillage Workgroup Introduces New Tillage Alternatives
What Has ANR Done?The UC Conservation Tillage Workgroup, with over 540 UC, farmer, USDA Natural Resources Conservation Service, private sector, and other public agency and environmental group members, develops knowledge and exchanges information on CT production systems, coordinates related research and extension programs related to CT, responds to needs for information on reduced tillage production alternatives, and conducts conferences, workshops, and training demonstrations. The workgroup conducted more than 60 different evaluations of CT practices throughout the Central Valley.
Workgroup extends conservation tillage informationThe workgroup established “local networks” of farmers, researchers, NRCS conservationists, and private sector partners to work on CT systems. Research demonstrates the potential to reduce dust emissions by over 50 percent using certain CT systems relative to standard tillage (ST) approaches and shows the ability to reduce fuel use, lower production costs, and, in some cases, increase farm profitability. These studies identified key “barriers” to more widespread adoption of CT in California, including problems with crop stand establishment, irrigation efficiency, and weed management. The most promising CT systems are being refined further in various farm and UC research center studies. Research shows that CT dairy forage production systems reduce dust emissions typically by 60 to 90 percent, relative to conventional production approaches, and that fuel use is significantly lower in CT cotton, tomato, and dairy systems. The workgroup tracked CT adoption throughout the Central Valley, documenting a 300 percent increase in the use of CT practices from 2002 to 2004.
