The Soil Conservation Service <br />completed an onfarm salinity control report in December 1977 <br />and provided a supplement in March 1980 to cover the onfarm- <br /> <br />related lateral improvement program. Implementation of the <br /> <br />USDA onfarm and related lateral improvement program was <br />initiated in 1979. <br /> <br />Fo!' 1982, SCS personnel estimate the Grand Valley <br />average annual salt load reduction by the USDA onfarm program <br />for the entire valley, including the Stage One area, to be <br /> <br />17,700 tons, with an average annual salinity concentration <br /> <br />reduction of 1.84 mg/l at Imperial Dam. SCS has initiated a <br /> <br />more comprehensive onfarm monitoring and evaluation program <br /> <br />in Grand Valley. Speciali zed monitoring equi pment has been <br />purchased and installed to measure climatic conditions (pre- <br />cipitation, wind direction and velocity, etc.) for use in <br />determining evapotranspiration rates and for measuring field <br /> <br />irrigation inflows and outflows. This oata will be used t.o <br /> <br />determine irrigation efficiencies and amounts of deep per co- <br /> <br />lation. The monitoring program was initiated on several <br /> <br />farms and will be further expanded to approximately 30 farms <br /> <br />per year as funoing levels increase in future years. <br /> <br />An agricultural extension agent has been hired in Grand <br /> <br />Valley through a cooperative agreement between Reclamation <br /> <br />and USDA Extension Service in conjunction with the Colorado <br /> <br />Cooperative Extension Service. The agent is working full <br /> <br />time to contact local landowners regarding the organization <br /> <br />-10.. <br /> <br />,t'.............: <br />
