Estimation of critical nutrient amounts based on input-output analysis in an agriculture watershed of eastern China

2009-12-01

Abstract excerpt

The concept of critical nutrient amounts (CNA) for a watershed was developed to address eutrophication in surface waters from diffuse (non-point) source pollution. CNA is defined as the maximum allowable applied or generated amount (AGA) of a nutrient from natural and human sources that can be emitted and still allow compliance with water quality standards. The CNA calculation method is based on properties of diff...
