Nutrient balances and present state of available nutrients in the soil

2001
A widely accepted approach to evaluate the sustainability of agricultural production concerning the nutrient status is to calculate nutrient balances (= input — output of nutrients). For this it is necessary to register all nutrient outputs (uptake by main product and by-product, leaching) and nutrient inputs (use of fertilisers, atmospheric deposition,

Data needs for nutrient balances

2011
One of the tools for evaluating the results of environmental action plans or EUdirectives related to nutrients in the agricultural sector is to follow the development of annually estimated nitrogen (N) and phosphorus (P) balances and surplus.Unlike greenhouse gas and ammonia emissions, countries are not required toreport N and P balances for ...
