Abstract

The nitrogen (N) balance (N input-N export by the grain) is often used to estimate the risk of N leaching from arable land. In a nine year study during the leaching seasons 1991/1992 to 1999/2000, the relationships between N fertilization, N balance and N leaching in the subsequent percolation period were investigated in a multifactorial field experiment near Kiel in NW Germany at the Hohenschulen Experimental Station. The crop rotation was oilseed rape (OSR)-winter wheat-winter barley, while soil tillage (minimum tillage without ploughing, conventional tillage), application of pig slurry (none, application in autumn, application in spring, application in autumn plus in spring), mineral N fertilization (none, 120 or 240 kg N ha-1 to cereals), and application of fungicides (none, intensive) were all varied. In each year the rotation and the treatments were located on the same plots. N leaching was calculated by multiplying the drainage volume with the respective N concentration obtained using ceramic suction cups. In all crops, N fertilization significantly increased the N balance in the order mineral N < spring slurry < autumn slurry. N leaching significantly correlated with the amount of percolation (P < 0.05). Highest annual N losses occurred with wheat following OSR (73 kg N ha-1) compared to the situation with OSR following barley (44 kg N ha-1). Without slurry, mineral N fertilization increased N leaching only slightly, whereas slurry, especially if applied in autumn, boosted N losses. Soil tillage and fungicide application had no significant effect on N leaching, although the latter showed a large influence on N balance. Increasing N balance progressively raised N leaching in the subsequent period with all crops, however, only 13-25% of the N balance surpluses originating from the preceding crop seem to leave the system via this pathway. The results indicate only a poor correlation between N balances and N leaching. In the short-term, therefore, the N balance is not an appropriate indicator for the environmental impact of N fertilization. However, if set up over a longer period, N balances may still give good estimates of the leaching potential arising from different management systems.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
