Plant Nitrogen Elements Determination

Nitrogen is the most important nutrient element in terms of plant growth, physiology and carbohydrate content. It is a constituent of chlorophyll, amino acids, proteins, alkaloids, and protoplasm. Organic nitrides in plant tissues can be divided into two types-protein nitrogen and non-protein nitrogen. Non-protein nitrogen includes amino acids, amides and a small number of inorganic nitrides, which are small molecules soluble in trichloroacetic acid (TCA) solution.

The content of nitrogen in plant tissue is closely related to physiological status and environmental conditions of plants. Therefore, the determination of its content is important to study the law of nitrogen absorption, transport, and metabolism of plants, as well as to determine the quality and nutritional value of agricultural products.

STEMart is able to efficiently and accurately determine the content of nitrogen elements in plant samples.
