Agricultural Irrigation Systems Detail
Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost,[1] suppressing weed growing in grain fields[2] and helping in preventing soil consolidation.[3] In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dryland farming. Irrigation systems are also used for dust suppression, disposal of sewage, and in mining. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area.
Irrigation systems appear to be fairly simple, they are actually quite advanced. One of the most pervasive irrigation systems is the center pivot system. At the pivot of this system is a source of water, which spreads to each individual segment. Rotation around the center pivot point is granted by individual electric motors found on each set of wheels. The outermost set of wheels controls the speed of revolution of the whole system. Typically, the outer wheels move at a faster rate than the inner wheels so as to maintain segment alignment; various angle sensors report to a computer which coordinates such alignment. The individual nozzles found on each segment vary in size (and therefore water emission) in order to achieve application uniformity—the closer to the center, the smaller the nozzle size.
