| Background | As an important class of compounds in soil, amino acids account for 15%-60% of total nitrogen in soil. They are important "stores" and "sources" in the process of soil nitrogen circulation and plant nutrient supply. They can meet the nitrogen nutrition needs of crops through mineralization, and can also be directly absorbed and utilized by plants. In addition, amino acids are also important nitrogen sources for soil microorganisms and have a direct impact on the structure, number and activity of soil microbial communities. Therefore, studying the changes in amino acid content in soil is of great significance to studying soil nitrogen circulation and its impact on plant physiological and ecological changes. CheKine™ Micro Soil Free Amino Acid (S-FAA) Content Assay Kit provides a simple, convenient, and rapid method for amino acid, which is suitable for the detection of soil. The principle is that the α-amino of amino acid can react with Ninhydrin hydrate to produce blue-purple substances, which has a maximum absorption peak at 570 nm. The amino acid content of the sample can be calculated by measuring the absorbance at 570 nm. |
