Abstract

Abstract The paper presents the results of experimental studies of the influence of the level of mineral nutrition and the variant composition of technological methods of care on the productivity of organic potatoes. The studies were carried out at the Experimental Station of the Institute for Engineering and Environmental Problems in Agricultural Production - Branch of Federal State Budgetary Scientific Institution “Federal Scientific AgroEngineering Center VIM near St. Petersburg. The soil of experimental plots is sod-podzolic light loamy gleyic on residual carbonate moraine loam. Soil resistance was measured with a Penetrologger. The use of deep loosening of the inter-row spacings during inter-row cultivation reduced the soil resistance in the inter-row spacing by about 20% and in the root formation zone by 13%. Deep loosening of the row spacings reduced the soil resistance in the experiment both with direct measurement after the technological operation to a depth of 60 cm, and within two months of measurements. With the combined use of compost and deep loosening, the yield increase was from 1.46% to 6.04% when comparing comparable doses. The maximum potato yield of 23.6 t /ha was obtained with deep loosening of row spacings and a poultry compost dose of 8 t /ha
