Reduction of N_2O emission by introduction of precision fertilisation

摘要

Introduction of precision fertilisation in grassland may reduce N_2O emissions. Three experiments were set up to investigate the effect of fertiliser type, avoiding urine spots and avoiding ditches. Fertiliser type showed a significant effect (p<0.001) on N_2O emissions. Avoiding N-fertilisation on urine spots reduced N_2O emission while the effect of avoiding ditches depended on the ground water level of the soil.
