Agricultural organic amendments may hold the key to conserve soil productivity while alleviate non-point source pollution of intensified hillslope cropping

Crop residue and pig manure slow down nitrogen release compared to synthetic fertilizer, reducing nitrogen loss through synchronized nutrient release and crop demand. Substituting up to 40% synthetic nitrogen with organic amendments can maintain high crop yield and significantly reduce nitrogen loss from sloping cropland.
