摘要: The authors present an empirical model used to estimate the effects of alternative farming practices on potential nitrogen runoff and leaching in 128,591 National Resource Inventory sites across Midwest Northern Plains United States. This integrates soils, climate, crops, management loss. is applied evaluation two policy scenarios; one deals with fertilizer application reduction other replaces continuous cropping crop rotations.
