Plant Sulfur Elements Determination

Sulfur is considered to be the fourth most important nutrient element after nitrogen, phosphorus and potassium in plants, accounting for about 0.1% of the plant weight. The main source of available sulfur for plant is sulfate in the soil, which is actively absorbed into the plant by its roots and transported to the aboveground parts via the xylem. Sulfur is a constituent of amino acids, chloroplasts, sulfatides, vitamins, coenzymes and substances related to stress tolerance and resistance to diseases and insect pests, so sulfur plays an extremely important role in photosynthesis, respiration, formation of cell membrane structures and response to biotic and abiotic stress. In addition, sulfur is closely related to the yield and quality of crops. Therefore, the determination and analysis of sulfur are essential.

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