Gross N transformation rates in soil system with contrasting Urochloa genotypes do not confirm the relevance of BNI as previously assessed in-vitro por Teutscherová, Nikola, Vázquez, Eduardo, Trubač, Jakub, Villegas, Daniel Mauricio, Subbarao, Guntur V., Pulleman, Mirjam Margreet, Arango, Jacobo

“…The discrepancy between the potential net nitrification rates assessed in laboratory assays (higher in low-BNI plants) and gross nitrification in pot or field experiments (no differences between genotypes) can be attributed to the out-competition of ammonia oxidizers by plant N uptake and ammonia immobilizing heterotrophic microbes, resulting in low nitrification under conditions where growing plants are present. …”
