<br />OaJECTIUE L. <br /> <br />Objective 2 is to evaluate the potential of increasing efficiency uSing surface <br />irrigation methods. <br /> <br /> <br />The adoption of low-application rate, high-frequency irrigation methods, may be unlikely <br />even if proven technically sound by field-scale experiments. Utilizing better management <br />practices for furrow irrigation could result in significant water savings with corresponding <br />reductions in salt return. Automated surface irrigation coupled with a tailwater reuse <br />system can achieve 90-95 percent application efficiency and uniformity coefficients of 90 <br /> <br />Gated pipe distributes <br /> <br />water to furrow <br /> <br />irrigated plots. <br /> <br />or above. Gated pipe is used to distribute water uniformly to the furrow irrigated plots. <br />Water applied to the soil, runoff, and changes in soil water storage are measured. The <br />computerized Department of Agriculture irrigation scheduling program is used to predict <br />proper time and amount of each irrigation. Leaching fractions of 10 and 20 percent are <br />being imposed. <br /> <br />Z~6Z00 <br />
