Investigation and model calculations of nitrogen dynamics from intensively managed agricultural ecosystems of South Oldenburg

, : Investigation and model calculations of nitrogen dynamics from intensively managed agricultural ecosystems of South Oldenburg. Okologie und Naturschutz im Agrarraum 19(2): 536-543

A consequence of the increasing use of liquid farm manure in agriculture are the problems of nitrate leaching and the increase of nitrate concn in the ground and drinking water. Investigations of the annual variation of nitrogen conversion and the processes of nitrogen transfer have been made since 1987 in the Vechta area of Germany.

A simple input-output model was constructed to evaluate the long-term net nitrogen (N) gain or loss or N self-sufficiency of several silvicultural systems. In general, short-rotation, whole-tree-harvest systems are not self-sufficient in N. They t...
