Irrigation and soil salinity management are of paramount importance to agriculture sustainability in desert agriculture. Because irrigation water and shallow ground water that fluxes up through the soil have salts, some level of excess irrigation (beyond crop consumptive use) must be applied to leach salts below the crop root zone. The various irrigation systems utilized, and the management of these systems, can have a profound impact on water delivered, leaching achieved, and resulting salt distribution.
