large-pot model experiments were conducted with maize under greenhouse conditions with the aim of studying the effect of different N fertiliser forms, water supplies and crop residues on the nitrogenous gas production in the rooting zone. Nitrogen fertiliser was applied in the form of KNO3 or NH4Cl. The experiment was done at two soil moisture levels, with or without the incorporation of maize crop residues into the soil, and with or without test plants. Gas traps were placed in the pots at a soil depth of 20 cm. During the growing season, the trapped soil air was analysed for NOx, N2O and N2. Practically the same N amounts evolved in the soil air with both chemical forms of N fertiliser at both soil moisture levels. expressed as a percentage of fertiliser N, the total amount of gaseous N evolved averaged 12.8% and 12.9% in the planted, and 23.8% and 24.3% in the unplanted pots with KNO3 and NH4Cl fertiliser, respectively. Higher soil moisture and the incorporation of crop residues resulted in higher NOx-N and N2O-N ratios within the total gaseous N evolved in the rooting zone.
