Dutch dairy farms produces in 2018 78.7 million kilogram phosphate which is 8.0 million kilogram less than in 2017. The Dutch national phosphate quota for the dairy industry is 84.9 million kilogram. However: this is more than 8 million kilogram more than the national dairy nitrogen quota. The lower production of phosphate and nitrogen is mainly caused by the decrease of the number of cows after the introduction of phosphate quota per farm. After this the number of dairy cows decrease about 60000 head or four percent. The number of youngstock decreased 150000 head or 14 percent.
