Soil Nitrate Nitrogen Detection Kit

Soil Nitrate Nitrogen Detection Kit

Nitrate nitrogen refers to the nitrogen contained in nitrate, and the organic matter in the soil decomposes to form ammonium salt, which is oxidized and turned into nitrate. Nitrogen nitrate in soil is one of the main forms of nitrogen absorbed by higher plants, and its content is directly related to the yield and quality of crops.

Under the condition of concentrated acid, NO3- reacts with salicylic acid to form nitrosalicylic acid, which is yellow under alkaline conditions (PH>12), and its color shade is directly proportional to the content within a certain range, and the nitrate nitrogen content can be calculated by colorimetric determination.
