Nitrification by soil nitrifiers may result in substantial losses of applied nitrogen through NO3 − leaching and N2O emission. The biological inhibition of nitrification by crop plants or pasture species is not well known. This study was conducted to evaluate the ability of three pasture species, Brachiaria humidicola, B. decumbens and Melinis minutiflora to inhibit nitrification. Plants were grown in a growth chamber for sixty days, fertilized with (NH4)2SO4. After harvesting, the soil was… CONTINUE READING
