The Balance of the Nitrogen in Agriculture

Abstract

Methodology addressing nitrogen balance issues is a suitable tool for verifying the correctness of agricultural management and shows the relation between nitrogen used in agriculture and its losses in gaseous form to air or in the form of nitrates to surface and groundwater. The assessment of nitrogen balance, greenhouse gas emissions and pollutants is closely linked and therefore requires the quantification of nitrogen sources used in agriculture. Synchronization of input data used to evaluate nitrogen flows in agriculture is essential to increasing the methodological level of reporting the nitrogen balance, greenhouse gas emissions and pollutants for the Czech Republic in terms of the requirements of international organizations
