Notes:
Summary Recent denitrification research is reviewed to answer questions a) how much N is lost from the soil as N2 and N2O and b) how do agronomic practices affect this loss? The methods used to quantify denitrification are also discussed. Gaseous losses of inorganic N range between the equivalent of 0 to 20 per cent of the fertilizer N applied to arable soils and 0–7 per cent on grassland soils. Losses are greater on undrained land and also after using direct drilling to establish arable crops. Appendix 1 summarizes reported measurements of gaseous N losses.
