Long description: A better understanding of the effect of soil fumigation on N mineralization and nitrification may help to optimize N fertilizer advice and predict NO–3 concentrations in crops and NO–3 leaching risks. De Neve et al. (1647–1652) relate differences in short- and long-term N mineralization and nitrification following soil fumigation with Cyanamid DD 95 to basic soil properties. The average short-term N mineralization was larger in fumigated than in nonfumigated soils, but the difference between fumigated and nonfumigated soils could not be related to soil properties. Long-term N mineralization rates were not significantly different between fumigated and nonfumigated soils. The nitrification rate constant and the time at which maximum nitrification was reached were strongly correlated with soil pH. However, because of lack of correlation between the effect of fumigation on N mineralization and soil properties, further research will be needed to take into account fumigation effects in fertilizer advising and prediction of NO–3 leaching risks.
