	bibo:abstract "AUTOMATION of surface irrigation offers exciting\npossibilities for today's irrigation farmer. It provides\na means for improving  water use efficiency\nand cutting labor requirements. Excessive water is often\nused in current irrigation methods; water application\nefficiencies usually do not average over 50 to 60 percent. Although\nmany factors affect irrigation efficiency, the water\nfacilities and management practices used by the individual\noperator have the greatest effect.\nCompetition for available national water supplies is increasing\nrapidly. Irrigators eventually may have to justify\ntheir use of water. They may not always be permitted to\nuse nearly twice the amount required to satisfy crop consumptive\nuse requirements."^^xsd:string;
