Abstract

© 2019 Agricultural non-point source pollution is deteriorating water quality in many regions. Little information is available on the nitrogen (N) and phosphorus (P) loss via leaching and runoff for different fertilizer types in rice-wheat agricultural systems. A field experiment was conducted to quantify and characterize the temporal dynamics of N and P loss for different fertilizer types. A rice-wheat rotation with no fertilizer (Control, CL), chemical fertilizer (CF) and organic fertilizer (OF) was conducted from 2013 to 2015 in Taihu Lake. Fertilization and precipitation resulted in varied N and P loss within and between seasons. Compared to percolation water, runoff was the dominant mec..
