High yield arable and crop farming demands a temporally and quantitatively determined application of plant nutrients according to field and culture. The nutrients may come from commercial fertilizers or from animal wastes. Regarding the dangers to soil, water and air, which come from current agricultural application measures for nitrogen, a sectoral approach for a nonpolluting liquid manure utilization cannot be used any longer. An integrated system approach has to be found, leading to a drastic improvement of nutrient utilization and hence to a considerably reduced nutrient use. This can be only expected, if the organic manure can be applicated at times, when losses through leaching and volatilization can be minimized.
