It was found that using surface-applied gypsum soil amendment to no-tilled soil could reduce runoff, erosion, and improve water quality related to nutrient runoff. Surface application of manure in a no-till system greatly increased the amount of nutrients in runoff water, but a co-application of gypsum amendment significantly reduced all major nutrients lost except nitrates.
