Abstract

Evaluation of an On-Farm Water Storage (OFWS) system as a Best Management Practice (BMP) for nutrient and sediment loading control and irrigation in East Mississippi has shown that the system can effectively reduce sediment and nutrient loading as it was able to capture 46 tons of sediment and 558 kg of phosphorus over the monitoring period. The system was also able to decrease nitrogen loading as shown from the nitrogen concentration in the captured storm runoff events although an accurate estimate could not be made using AnnAGNPS because adequate model input data was not available. The system was able to provide about 63 million gallons of water for irrigation as a result of which increased corn and soybean yield was also obtained in irrigated fields when compared to non-irrigated fields. Water from the storage pond used for irrigation did not have adequate nutrient recycling to reduce commercial fertilizer application.
