Gross nutrient balance (CSI 025) - Assessment published Nov 2005: At EU-15 level the gross nitrogen balance in 2000 was calculated to be 55 kg/ha, which is 16% lower than the balance estimate in 1990, which was 66 kg/ha. In 2000 the gross nitrogen balance ranged from 37 kg/ha (Italy) to 226 kg/ha (the Netherlands). All national gross nitrogen balances show a decline in estimates of the gross nitrogen balance (kg/ha) between 1990 and 2000, apart from Ireland (22% increase) and Spain (47% increase). The following Member States showed organic fertiliser application rates greater than the threshold of 170 kg/ha specified by the Nitrates Directive in 2000: the Netherlands (206 kg/ha) and Belgium (204 kg/ha). The general decline in nitrogen balance surpluses is due to a small decrease in nitrogen input rates (-1.0%) and a significant increase in nitrogen output rates (10%).

Gross nutrient balance at national level: EEA calculations on the basis of the following: Harvested crops and forage Crop area (Eurostat's ZPA1 data set or Farm Structure Survey); Livestock numbers (Eurostat's ZPA1 data set or Farm Structure Survey); Livestock excretion rates (OECD or averaged coefficients from Member States); Fertiliser rates (EFMA); Nitrogen fixation (OECD or averaged coefficients from Member States Farm Structure Survey); Atmospheric Deposition (EMEP); Yields (Eurostat's ZPA1 data set or average coefficients from Member States).
