The term "conservation irrigation" is relatively new. Only in recent years has it become part of the terminology of irrigated agriculture in the West. "Conservation irrigation" is simply using irrigated soils and irrigation water in a way that will insure high production without the waste of either water or soil. It means using cropping, irrigation, and cultural practices that will maintain the land in permanent agriculture. Better methods hold a practical solution to both water problems and land problems. Whether you are a large irrigator or small, you will find the answers to many of your irrigation problems in the following pages. They are based on the latest scientific information and the experience of irrigators who are now practicing conservation irrigation.
