文摘
- •
AgNPs and AgNO3 significantly affected soil urease and phosphatase activities
- •
AgNPs had more negative effects than Ag+ on soil enzyme activities
- •
AgNPs and Ag+ had no effect or even stimulated soil respiration at low concentrations
- •
AgNPs and Ag+ negatively affected SIR at high concentrations (≥ 10 mg Ag kg− 1)
- •
soil urease and phosphatase activities were more sensitive than respiration to Ag
