Field studies were conducted over 2 years to determine the response of soil microbial biomass pool to biochar and N fertilizer combinations in a rain-fed rice cropping system. Biochar was applied at four doses: 0 t ha−1, 3 t ha−1, 6 t ha−1 and 12 t ha−1 in combination with N fertilizer at four rates: 0 kg ha−1, 30 kg ha−1, 60 kg ha−1 and 90 kg ha−1 to a Typic Paleustalf Alfisol. Soil samples from...
Purpose Biochar and inorganic fertilizer when co-applied have been reported to increase crop yield and enhance soil fertility. However, studies on this complementary effect on soil properties and rain-fed upland rice performance in Sub-Saharan Africa are still scanty. Methods Field factorial studies conducted over 2 years was set up to investigate the interactions between rice husk biochar and inorganic...
