Soil Neutral/Alkaline Phosphorous Content Assay kit

Alkaline phosphorus is the phosphorus component in the soil that can be absorbed by plants, including all water-soluble phosphorus, part of adsorbed phosphorus, part of slightly soluble inorganic phosphorus and minerals. The alkaline phosphorus in the soil is one of the main factors restricting plant growth.

The alkali-soluble phosphorus and adsorbed phosphorus are extracted by the weak alkali method, and the molybdenum blue and phosphate generate a 660nm characteristic absorption peak.
