2. Figure 1
New Dutch manure policy after quota abolition (the “Dairy Act”). The total surplus of 2015 is based on farm-specific excretion factors, whereas calculation of surpluses A, B and the phosphate quota are based on standard excretion factors per type of animal.

3. Figure 2
Nitrogen (N) and phosphate (P2O5) farm surpluses per hectare for an average Dutch dairy farm before quota abolition (2014) and after quota abolition (2016). Results A to E are variants of 2016 scenario: A=increased barn capacity, B=higher field and cow productivity, C=low manure disposal and processing prices, D=low land price, and E=higher milk price.

Greenhouse gas emissions [kg of CO2 equivalents (CO2-eq) per tonne of fat- and protein-corrected milk (FPCM)] for an average Dutch dairy farm before quota abolition (2014) and after quota abolition (2016). Results A to E are variants of scenario: A=increased barn capacity, B=higher field and cow productivity, C=low manure disposal and processing prices, D=low land price, and E=higher milk price.
