Overview

Our ongoing and past findings indicate substantial reduction in the soil nitrification potential from cultivation of B. humdicola due to accumulation of BNIs in soil systems. Other research groups working on Hyperrhenia diplandra pasture grasses in West Africa noticed a very stable BNI effect (but not properly quantified yet) on nitrification potential in soils. Thus, the aim of this research is to characterize the residual-BNI function from B. humidicola (BH) for the stability and intensity of BNI effect on soil nitrification potential, nitrogen-recovery and N-use efficiency in maize and soybean using the BNI-residual effect from a long-term cultivation (> 10 year pasture) of BH pasture.
