The Effectiveness of Zeolite Enriched with Amino Acids in the Cultivation of Crops in the Middle Volga Region (on the Example of Millet)

The paper presents the results of studies on effectiveness zeolite, including enriched with amino acids, in cultivation millet. study was carried out experimental field Ulyanovsk State Agrarian University 2019 by following scheme: 1. Control, 2. Zeolite 500 kg/ha, 3. kg/ha. In 2020, options were introduced into scheme. 250 4. kg/ha 5. soil typical medium loamy chernozem. and zeolite fertilizers have a positive effect agrophysical, water-physical agrochemical properties soil. content agronomically valuable aggregates arable layer increased 5.7 11.5 %, respectively; reserves productive moisture 9-11 mm, amount mineral nitrogen 0.5 6.5 mg/kg, available phosphorus 9 16 potassium – per 6 8 mg/kg use acids dose grain yield more than one ton hectare significant increase environmental safety. For millet, it is most feasible to
