However, <br /> <br />these methods have not yet enjoyed wide acceptance nor are they suitable on <br /> <br />all soils in the valley. Demonstration type projects will be needed to <br /> <br />enhance their use. Once in use they can increase i=igation efficiency by <br /> <br />15 to 35 percent in those fields where they are installed, with a similar <br /> <br />magnitude of reduction on the salt load pickup attributed to those fields. <br /> <br />Fifth, irrigation water must be delivered to each farm at the location, <br /> <br />elevation, flow rate, and pressure needed for proper operation of the <br /> <br />improved on-farm system. Therefore, a segment of the off-farm lateral must <br /> <br />be designed and built as an integral part of the on-farm improvement pro- <br /> <br />gram to assure accrual of on-farm benefits. Improvements in the lateral <br /> <br />system to be implemented through authorities of the USDA w:Lll be carried to <br /> <br />the point needed to assure proper operation of the on-farm improvements. <br /> <br />Progress in Fiscal Year 1979 included: <br /> <br />Irrigation Pipeline---------_______________________ <br />Concrete Ditch Lining-------------------___________ <br />Drip Systems-----------____________________________ <br />Semi-Automated Gated Pipe----------------__________ <br />Land Leveling------------__________________________ <br />Semi-Automated Ported Concrete Ditch--------------- <br /> <br />6:~,ooo Feet <br />23,500 Feet <br />5 Feet <br />2;;,000 Feet <br />450 Acres <br />1'1,000 Feet <br />
