硫是含硫氨基酸和蛋白质的必要组成元素，直接参与农作物的生长发育，影响农作物的品质。土壤硫主要来自母质、灌溉水、大气干湿沉降以及施肥等，对农林畜牧具有重要作用。因此，通过对土壤有效硫含量的测定，合理施用硫肥，对提高农作物的产量和品质起着关键作用。该产品可检测土壤样本。在该试剂盒中，从土壤中浸提出的硫基本上以SO₄²⁻形式存在，在酸性介质中，SO₄²⁻与Ba²⁺反应生成溶解度很小的BaSO₄白色沉淀，利用硫酸钡比浊法来测定土壤有效硫含量。
Sulfur is an essential constituent element of sulfur-containing amino acids and proteins, directly participating in the growth and development of crops and affecting their quality. Soil sulfur primarily originates from parent materials, irrigation water, atmospheric dry and wet deposition, and fertilization, playing a vital role in agriculture, forestry, and animal husbandry. Therefore, determining the available sulfur content in soil and applying sulfur fertilizers rationally is crucial for improving crop yield and quality. This product is suitable for detecting soil samples. In this assay kit, the sulfur extracted from the soil exists mainly in the form of SO₄²⁻. In an acidic medium, SO₄²⁻ reacts with Ba²⁺ to form a white precipitate of BaSO₄, which has very low solubility. The available sulfur content in the soil is determined using the barium sulfate turbidimetry method.
