Increased soil enzyme activity is an indicator of excellent soil health. The activities of soil β-glucosidase, arylsulfatase, and acid phosphatase are determined by quantifying p-nitrophenol, the product of degradation of p-nitrophenyl substrates during soil incubation. However, some p-nitrophenol m...
