Summary

The amount of internationally published evidence on the effects of grain legumes on nitrate leaching is sparse and some studies may have weak points. Nevertheless, this mini-review indicates that the level of N leaching is 0–20 kg N ha-1 greater after pea than after cereals. Methods to prevent N leaching should be further developed and there is a need to genetically improve the root systems of grain legumes.
