Soil Neutral Phosphatase (S-NP) Assay Kit

Note: Take two or three different samples for prediction before test.

Operation Equipment: Spectrophotometer

Catalog Number: AK0546

Product Description:

Soil phosphatase  is  an  enzyme which  catalyzes  soil  organic phosphate  mineralization,  the  activity influences the decomposition and transformation of organic phosphate and its bio-availability directly, which is the indicator of evaluating the direction and intensity of soil phosphorus bio-transformation. Soil phosphatase is influenced by the content of carbon, nitrogen, available phosphorus in the soil and pH. Soil phosphatase is divided into three types: acidic, neutral and alkaline phosphatase according to the optimum

pH.

 

In neutral condition, soil neutral phosphatase (S-NP) can catalyzes the hydrolysis of disodium phenyl phosphate to produce phenol and disodium hydrogen phosphate, the activity of S-NP can be calculate by detecting the content of phenol.
