Irrigation water has dissolved salts and minerals. Those salts and minerals are left behind as the water evaporates. Soil that is high in salt is not favorable for growing most crops.

Why must farmland be irrigated?
Farmland doesn't have to be irrigated. Irrigation is only necessary if there isn't enough moisture in the form of precipitation to meet the needs of a growing crop, be it corn, soybeans, timothy, alfalfa, wheat, or rice. Irrigation is also used as a means to boost crop production (for the same reasons described previously) or pasture production in a dryland environment where a producer wants to have a pasture that is of high quality for his/her livestock. As stated above, irrigation isn't always necessary. Many parts of the world raise crops or has pastureland that never sees any level of irrigation because there is sufficient moisture to support crop production from the rain that falls from the sky, so much so that irrigation is considered not cost effective. Even the areas that get irrigated still see rainfall, and some years, farmers may recieve enough rainfall that irrigation doesn't need to be used. Other years, though, which may occur more often than the years of "excess" moisture (what area you live in depends on what you would consider "excess" in moisture levels), irrigation is necessary to support crop production.
