It's working for almond growers in Merced County, the Clinton administration likes it, and now there's money for walnut farmers in Yolo and Solano counties to participate in a new Biologically Integrated Orchard Systems program. More than $200,000 in grower incentives and technical support is now available for the walnut BIOS program, which offers technical support and financial incentives for farmers who wish to reduce the use of agricultural chemicals. Chuck Ingels, perennial cropping systems analyst for the UC Davis-based Sustainable Agriculture Research and Education Program and a member of the BIOS management team, notes that the program is open to 20 walnut growers, each of whom will enroll approximately 30 acres in the program. With the help of the management team, farmers and their pest control advisors will develop a farm plan and participate in on-farm workshops, cover crop management, innovative equipment use, beneficial insect releases, and earthworm management, according to Ingels.
