Abstract

Lysimeter experiments with application of N-15 in growth chambers were used to investigate to what extent the growth of oil radish can prevent by temporary biological N conservation the nitrogen percolation and leaching during late autumn and early winter periods. It could be shown that the oil radish plants incorporated 47% of the applied N-15 and thus reduced substantially the N-15 percolation to the deeper soil layers (60 - 100 cm) and the N-15 leaching losses. Before giving final recommendations, the fate of the N-15 contained in the oil radish mustbe examined in the late winter and early spring periods, after freezing of the plants.
