Test Principle:
Determination of Significance：

Sulfur is an essential constituent element of sulfur-containing amino acids and proteins, which directly participates in the growth and development of crops and affects the quality of crops. Soil sulfur mainly comes from parent material, irrigation water, atmospheric sedimentation and fertilization, which plays an important role in agriculture, forestry and animal husbandry. Therefore, through the determination of the effective sulfur content in the soil, the rational application of sulfur fertilizers plays a key role in improving the yield and quality of crops.

Measurement Principle：

Sulfur extracted from the soil basically exists in the form of SO42-. In an acidic medium, SO42- reacts with Ba2+ to form a white precipitate of BaSO4 with little solubility. The effective sulfur content of the soil is determined by the barium sulfate turbidimetric method.
