文摘

Substance Flow Analysis and The Soil and Water Assessment Tool (SWAT) were linked. SWAT reveals the spatial variability of nutrient flows in different areas. Spatial variability was calculated via weighted average and standard deviation. Several improved agricultural management practices were simulated. No-till cropping reduces half of the nutrient loss in the area.
