We all depend on agriculture for sustenance. When compared to seafood and livestock, cropping systems provide the primary source of nutrition. Yields and productivity of cropping systems must grow to meet the demands of a growing population. Once seeds are available, a successful cropping season is determined by water. There are two sources for this: irrigation and precipitation. Irrigation water is a major input to agriculture, especially in semi-arid and arid regions. In a recent appraisal for the Soil and Water Resources Conservation Act, the USDA identified irrigation water conservation as a national need. Under-watering induces stresses and adversely impacts both crop growth and yields. Over-watering, on the other hand, leads to nutrient runoff, soil erosion, and water waste. Farms are also impacted by the adverse effects of droughts, variability in precipitation, and lengthening of the growing season. The proposed effort with its emphasis on water management and conservation represents an adaptation to the head winds often encountered at farms. The effort addresses the interrelated aspects of over-watering (soil erosion and nutrient runoff) and underwatering (adverse crop yields and stress) while ensuring sustainability and profitability of agricultural systems.
