摘要: To control the dissolved reactive phosphorus (DRP) concentration in a soil solution, number of amendments were tested. In current study, Blast Furnace Slag (BFS) and Water Treatment Residues (WTR) tested on bare under two rainfall intensities roughness levels. The was fertilized with P (KH2PO4) at rate 400 kg ha−1 while BFS WTR applied 5 g per 100 soil. Two levels exposed to artificial 30 65 mm h−1. Three events performed each treatment. runoff water generated over an area 0.5 m2 slope 8% collected different time intervals analyzed for DRP, Al, Fe, K concentrations. results showed that, regardless intensity roughness, DRP increased increasing from unamended plots. However, BFS- WTR-amended soils, decreased time...
