Center Pivot Irrigation
Center pivot irrigation using LESA (Low Elevation Spray Application). This mechanism significantly reduces water use on farmland by accurate application while also limiting evaporation. Reductions of water use on agricultural land will lead to a decrease of surface runoff and ultimately limit the amount of fertilizer and organic matter entering waterways.
