Offered Papers Theme A: Efficient Production from Grassland
Description
Organic nitrogen (N) accumulates in the soil in temporary grasslands. This accumulation is especially important when mineral N fertilisation is high. Legume-based temporary grasslands may also supply the soil with nitrogen through fixation of atmospheric N, for instance in organic farming. When ploughing temporary grassland, great amounts of mineral nitrogen can be released through the process of decomposition and mineralisation of soil organic matter. This mineral nitrogen can be taken up by succeeding crops. The aim of this experiment was to evaluate the effect of temporary grasslands of different ages, N fertilisation levels and legume contents on winter wheat yields in a crop rotation.
