Abstract
Today, perennial plants of the natural flora are a raw material resource for the production of drought-resistant and heat-resistant feeds, among which Eurotia Ceratoides occupies a special place. In this work, the chemical properties of Eurotia Ceratoides latens (J.F. Gmel) were studied, the humus content in the soil was determined, and the chemical and physico-chemical properties of light gray soil (humus, water, carbonate ions, nitrogen) were revealed. The humus content was determined based on the oxidation of organic carbon with chromic acid to carbon dioxide. The chemical composition of Eurotia Ceratoides Latens was analyzed for the content of nutrients in the plant (protein, fiber, fat, nitrogen-free extractables, ash) and water-soluble substances (C, CO2, Ca, Mg). It was found that the ash content in plants almost does not change in the phases of vegetation with the age of plants and ranges from 9,11-10,05%, respectively, and the calcium content was at the level of 3,67- 4,90. The content of «crude» fiber was determined using the Soxlet apparatus, the content of calcium cations in the soil was evaluated by the complexometric method, and the Kjeldahl method was used to determine crude protein, crude fat by ether extraction, nitrogen-free extractives in ash by precipitation with a saturated solution of ammonium oxalate, and phosphorus by the colorimetric method. The nutritional value of Eurotia Ceratoides latens has been revealed.
