    Uittreksel

    The eutrophication of surface and ground water from agricultural activities is a major concern for EU policy. In this context, Flanders has to meet the objectives of the European Nitrates Directive. Overall soil condition, for example C sources, microbiology and soil structure affect N availability. C and N turnover processes may be affected by the fertilization practice. Having explored data from long-term cropping experiments, Mulvaney et al. (2009) stated that synthetic N depletes soil N. Our objective was to study the effect of applied mineral N on the N mineralization process in cultivated land with a short-term perspective. The research question was if a priming effect would take place, i.e. an enhancement of the net N release from soil organic matter after a mineral N input.
