This report describes the implementation of the set environmental policy with regard to nutrients (as developed until 1991) in the agricultural sector of the Dutch economy and its effects on eutrofication, ammonia-emissions, and heavy metals supply to soils. Part one describes the assumptions made on key variables, necessary to calculate the amount of manure produced and its accompanying emissions. Each of these variables require quantification of its development over time, up until 2010. Such variables include; livestock numbers, composition of excreta, penetration of techniques that reduce ammonia-volatilization. Part two gives an overview of (intermediate and final) results of the calculations and presents data on ammonia emissions from manure, N-, and P-content of manure produced, application rates of N and P, K, As, Cd, Cu, Pb and Zn (both from manure and chemical fertilizer) on crop-soil-combinations. It also contains material balances for nitrogen, phosporus and potassium for the Dutch agricultural system in the years 1986, 1989, 2000 and 2010.
