Indicator voor stikstofmineralisatie op gescheurd grasland = Indicator of nitrogen mineralisation on broken meadowland

This report addresses the results of an experiment with field trials with potatoes and silage maize onsandy soil in 2006 in order to obtain a suitable indicator for predicting N-mineralisation after ploughing the grassland. This study is part of a larger project with more field trials and a laboratory experiment. Ploughed grassland on the locations selected provided much nitrogen, due to which it was not possible to infer an indicator from the crop response for adjusting nitrogen recommendation. N-total seems to be the most promising parameter in predicting nitrogen mineralisation
