The yield of potatoes in Russia remains low due to cultivation not only in production enterprises, but also in private farms, where cultivation is labor-intensive, non-industrial type. However, potatoes grown in PSP can be integrated into the segment of production of organic potatoes with the support of the Ministry of agriculture of the Russian Federation and transferred from the sector of personal consumption to the format of commercial activity. The peculiarity of organic farming is the refusal of cultivation technologies to use any chemical compounds. Therefore, the use of natural material-a concentrate of glauconite sand from the Bondar Deposit in the Tambov region is becoming more and more relevant. The purpose of our work is to study the effect of glauconite sand concentrate on potato productivity. The research was carried out in 2018–2019 on the site of the vegetable growing laboratory of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. Sod-podzolic soils are medium-loamy, the capacity of the arable layer is 20–22 cm, easily hydrolyzed nitrogen is 9.3 mg per 100 g of soil, phosphorus is 15.0, potassium is 8.3 mg per 100 g of soil, humus content is 2.6%, pH – 5.8. We used the Udacha variety with different concentrations of glauconite sands (10 g/plant, 20 g/plant, 30 g/plant, 40 g/plant). The repeatability of experiments is three-fold. The variants in the experiment were placed by rendomized method. The area of one experimental plot is 25 m2. The planting scheme is 70×35 cm. The density of standing 46.7 thousand plants per ha. Seeds of the average fraction (40–80 g), elite, were used for planting. All variants are planted simultaneously in one year. Observations and records of phenological, biometric, and crop structure were made. Cultivation technology is standard. Adding the natural mineral glauconite sands when cultivating early potatoes gives an increase in yield up to 30.2%, the best rate is 30 g/plant.
