The nutrient status of European soils differs according to the parent material, the predominant crops and the management of the soil. Depending on these variables we can find soils with an excess of nutrients and others with a dramatic need of nutrients.  To evaluate these differences a European scale view has been made where the nutrient balance has been mapped on a nut3 level for the whole of Europe. The budgets or balances used in SEA2LAND include inputs (manure, seeds and planting material and biological fixation) and outputs (removal of nutrients with the harvest of crops, harvest and grazing of fodder, removal and burning of crop residues.  The difference between nutrient needs and local nutrient availability is what we have called “balance” trying to highlight the areas that need fertilizers supply and those that have a nutrient surplus. Map on N,P,K, Ca and Mg imbalances has been obtained. The results obtained are an approximation based on available data.

BAL: Nitrogen balance (Inputs minus Outputs) (tonnes N)

BAL_UAA: Nitrogen balance per hectare


The maps obtained can be a very useful tool for advisory services to delimit the areas most in need of fertilization as well as to determine the specific fertilizers needed in each area, while fertilizer producers can focus on the areas most in need and the nutrients most needed in each area, while politicians can use this type of mapping to define action measures in specific areas.
