+{{  :capri:concept:nbal.jpg?520|}}
+The nitrogen balances are calculated based on the combination of the soil surface and farm gate balance approach, and are closely linked to the estimation of crop specific [[capri:concept:SpatFert|fertilizer application rates]].
+The **gross balance** is defined as the difference between the different **nitrogen inputs**:
+  * Nitrogen from mineral fertilizer
+  * Nitrogen from manure
+  * Nitrogen in crop residues
+  * Nitrogen from biological fixation by legmuninosae
+  * Nitrogen from atompsheric deposition
+and export by **harvested crop material**. In order to get a more refined pressure indicators on soils and water, an [[capri:concept:ammo|emission factor approach]] estimates gaseous losses during manure storage and in stable as well as during application of organic and merinal fertilizer, and thus calculates the nitrogen which could either run-off, leach below the root zone or be stored in soils.
