Phosphorus and cover crop management practices affect phosphorus speciation in soils and eroded sediments.

ABSTRACT: Agricultural runoff often contains P in dissolved and sediment-bound forms, decreasing surface water quality. No-till and cover cropping conservation practices have been recommended for reducing erosion and nutrient loss from cropping systems. The overall aims of this study were to characterize and evaluate the effects of fertilizer (placement and source) and cover crop management on P speciation in surface runoff sediments and source soil. In 2014, a field-scale experiment was established in a no-till, corn (Zea mays L.)-soybean (Glycine max L.) cropping system with two cover crop treatments (with and without a winter crop; winter wheat [Triticum aestivum L.], rapeseed [Brassica napus L.], hairy vetch [Vicia villosa Roth], winter triticale [×Triticosecale Wittm.], and cereal rye [Secale c
