Nitrogen acquisition by two U. humidicola genotypes differing in biological nitrification inhibition (BNI) capacity and associated microorganisms

Popis výsledku v původním jazyce

Biological nitrification inhibition (BNI) has been considered a plant strategy to increase N use efficiency by reducing N losses via N2O emissions or nitrate leaching. However, recent studies have revealed no difference in gross nitrate production among Urochloa humidicola genotypes with previously described high- and low-BNI capacity and pointed towards a crucial role for microbial N immobilization. In the current greenhouse study, we compared the (15) N acquisition by two U. humidicola genotypes (with high- and low-BNI capacity) and their soil-associated microorganisms at four points in time after fertilization (50 kg N ha(-1)). Soil microorganisms slightly out-competed both genotypes during the first 24 h after fertilization, and microorganisms associated with high-BNI genotype immobilized more N than microbes associated with low-BNI plants. Nevertheless, by the end of the experiment, low-BNI plant genotype had acquired more (15) N, despite higher to N2O emissions. Furthermore, higher (15) N root-
