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

Abstract

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