Can grass roots decrease soil microbial biomass to utilize its nitrogen?

Recent advances in grassland production and management: 194-201
Can grass roots decrease soil microbial biomass to utilize its nitrogen?
The amount of fungal biomass that was dominant in microbial biomass was small in soils containing a lot of live roots near the soil surface of a pasture in early spring. This relationship was also found in untreated and air-dried grassland soils with increased grass biomass resulting from N application. In the absence of grass, N application did not reduce fungal biomass in the soil.
