Show SCD Test Demonstrates How To Make Irrigation Water Cover More Acreage How to make your irrigation water cover the maximum acreage ac-reage was demonstrated at a test run conducted by Grant E. Chugg, S.C.S. engineer, on M. J. Bnson's farm in Ioka, seven miles southwest of Roosevelt. Mr. Benson has been reorganizing reorgan-izing his irrigation system with the Uintah Basin SCD according- to his Soil Conservation plan. One of the practices called for improved application of irrigation ir-rigation water. . To determine the irrigation efficiency, the SCS has developed develop-ed a system of measuring the water that runs down about five different furrows. I he depth the water soaks, the horizontal hor-izontal movement of the water, the soil texture, and the slope of the field are all studied. At the end of the test the ideal length of run and amount ot water to apply are determined. The test conducted on Mr. Benson's farm indicated that approximately ap-proximately eight acres inches were applied, and his runs were 1000 feet. He plans to change this so he will apply normally only four acre inches per irrigation irri-gation in runs 500 feet long Thus the field can be irrigated in two-thirds the time previously previous-ly required. , . Tests of this kind are being conducted throughout the Basin with SCD cooperators to get better use of their irrigat on water. Some tests have revealed that as much as 14 acre feet of water per acre have been applied ap-plied on some irrigated lands Fn one season. This excessive amount of water leaches the Pnt food out of the sml and destroys the soil structure for FarSinterested in running these irrigation tests should con-1 con-1 act their local district supervisor super-visor or SCS technician. |
