FIELD: agricultural production.
SUBSTANCE: invention relates to agricultural production, in particular to a method for the quantitative determination of calcium, phosphorus and sodium in compound feeds or compound feed raw materials. The method is characterized by the fact that a sample of compound feed or compound feed raw material is taken, it is crushed to a fraction of less than 1 mm, after which it is subjected to ashing or mineralization based on the oxidation of organic substances by strong oxidants, and the analysis is carried out on a SKALAR San++ flow-through analyzer.
EFFECT: invention is aimed at determining the amount of calcium, phosphorus and sodium in compound feeds or compound feed raw materials.
