...izers (viz., urea for N, single superphosphate for P and potassium chloride for K) on soil respiration and N mineralization during lab incubation experiment under wheat-mungbean and wheat-maize cropping systems. The rate of CO2 evolution increased significantly (P<0.05) with increasing level of added biochar during each incubation period. At day 2, the rate of CO2 evolution increased from 142 µg CO2 g-1 soil...
