 +
 +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.
