Book Description
Excerpt from Pneumatic Valves for Automation of Irrigation Systems Competition for water among domestic, industrial, recreational, and agricultural users in the Western United States is increasing at an alarming rate. Some authorities believe that irri gated agriculture, one of the low efficiency users of Water, could be forced to yield part of its water rights for other purposes unless conservation practices are adopted. A major cause for inefficient use of water, particularly with surface irrigation systems, is the high labor cost. Coupled with inexpensive water. Farmers are reluctant to use additional labor just to conserve water. Rather, the farmer often adjusts water application time to 'labor patterns dictated by general farm operations. The 12-hour irrigation set used by many farmers often results in excessive percolation and runoff losses, particularly where soils are coarser' textured and intake rates are high. Furthermore, excessive use of water usually leads to drain age and salinity problems that are costly to alleviate.
