Short summary
Ammonium additions had stronger inhibition effects on soil microbial biomass of different communities than nitrate addition. However, inhibition effects of nitrate additions on P hydrolase were stronger than ammonium additions, but not on C- and N-hydrolase and oxidase. Ammonium additions decreased N-acquisition specific enzyme activities normalized by total microbial biomass, but increased P-acquisition specific enzyme activities. Different effects on soil pH may explain the different effects.
