Soils are being continuously exposed to large amounts of engineered nanoparticles (ENPs), especially silver nanoparticles (AgNPs). These materials can interact with microbial enzyme activity, stability and/or specificity affecting their role in nutrient cycling. Specific enzyme activity measurements have potential to serve as bioindicator in identifying major changes in the soil environment. Present study investigated the effect of AgNPs on soil enzymes known to play a critical role in mineralization of C, N, P and S in the soil. Soil samples were collected from surface layer (0-10 cm) of a Wrengart silt loam series. The study used two sizes (10 and …
