Plant Nitrate Nitrogen Assay Kit

Plant Nitrate Nitrogen Assay Kit 

Nitrate nitrogen is the most important nitrogen source for plants. The content of nitrate nitrogen in plants reflects the supply of nitrate nitrogen in the soil and can be used as an indicator for soil nitrogen fertilizer. Determining the nitrate nitrogen content in plants not only helps reflect the nitrogen nutrition status of plants but also is of great significance for evaluating the quality of vegetables and processed products made from plant raw materials.

Under concentrated acid conditions, nitrate ions (NO₃⁻) react with salicylic acid to form nitrosalicylic acid. Nitrosalicylic acid appears yellow under alkaline conditions (pH > 12). Within a certain range, the depth of the yellow color is proportional to its content, and the nitrate nitrogen content can be calculated through colorimetric determination.
