Table 1.
Mean values of mineralisation (μg NH4-N g−1 24 h−1), nitrate reductase activity (μg N g−1 24 h−1) and nitrification rate (ng N g−1 24 h−1) in the Rothwald soil at 30% WFPS, 55% WFPS and 70% WFPS and 5°C, 10°C, 15°C, 20°C and 25°C. Different lower case characters represent significant differences, p<0.05.
