土壤有机质是指存在于土壤中的所含碳的有机物质。它包括各种动植物的残体、微生物体及其会分解和合成的各种有机质。土壤有机质是土壤固相部分的重要组成成分，其含量水平是衡量土壤肥力的重要指标之一对土壤形成、土壤肥力、环境保护及农林业可持续发展等方面都有着极其重要作用的意义。该产品可检测土壤样本。在该试剂盒中，在加热条件下，土壤样品中的有机质被过量重铬酸钾-硫酸溶液氧化，重铬酸钾中的六价铬(Cr⁶⁺)被还原为三价铬(Cr³⁺)，其含量与样品中有机质的含量成正比，于 585 nm 波长处测定吸光度，根据三价铬(Cr³⁺)的含量计算有机质含量。
Soil organic matter refers to the carbon-containing organic substances present in soil. It includes various plant and animal residues, microbial bodies, and the diverse organic materials resulting from their decomposition and synthesis. As a crucial component of the solid phase of soil, its content level is one of the important indicators for evaluating soil fertility. It plays an extremely significant role in soil formation, soil fertility, environmental protection, and the sustainable development of agriculture and forestry. This product is suitable for detecting soil samples. In this assay kit, under heating conditions, the organic matter in the soil sample is oxidized by an excess of potassium dichromate-sulfuric acid solution. The hexavalent chromium (Cr⁶⁺) in the potassium dichromate is reduced to trivalent chromium (Cr³⁺), and its content is proportional to the organic matter content in the sample. The absorbance is measured at a wavelength of 585 nm, and the organic matter content is calculated based on the amount of trivalent chromium (Cr³⁺).
