Developments in mineral surpluses and water quality in the Dutch dairy sector, 1960-2010
In line with the agricultural policy during 1950-1980, which aimed at increasing production levels, inputs of fertiliser and purchased fodder increased considerably, resulting in higher milk production levels per hectare and per cow on Dutch dairy farms. This intensification of the dairy farming system resulted in a nitrogen soil surplus of 400 kg/ha and a phosphate surplus of 82 kg/ha on average on dairy farms in 1985, which led to high nitrate contents in the water leaving the root zone, especially in the Sand region.
