Effect of compost application with or without urea on soil a pH b electrical conductivity (dSm−1) and c organic matter content after 49 days of incubation. Bars with the same letters are not statistically different at P < 0.05. Bars represent the standard deviation of the mean (n = 3). T1: 500 g soil + 5000 kg ha−1 compost, T2: 500 g soil + 5000 kg ha−1 compost + 100 kg N ha−1, T3: 500 g soil + 5000 kg ha−1 compost + 200 kg N ha−1, T4: 500 g soil + 5000 kg ha−1 compost + 400 kg ha−1
