“…Calcium losses from limed soils during fertilization are 2-4 times higher than magnesium losses [16]. In the orchard soils of the South of Russia, the calcium leaching from topsoil occurs as a result of irrigation and fertigation, and simultaneously the upper soil layers enriched with magnesium [17]. In rainfed conditions of our experimental orchard a decrease of the calcium level was also noted due to the every-year application of nitrogen and potash fertilizers with a relatively constant level of exchangeable magnesium.…”

The purpose of the research was to evaluate the changes in the agrochemical properties of the sour cherry orchard soil after the permanent soil fertilization with urea and potassium sulfate. The field experiment was conducted during 2017-2021 in the soil and climatic conditions of the Central Russian Upland (Oryol region). ‘Turgenevka’ sour cherry trees grafted on the rootstock V-2-180 were planted in 2015 at a distance of 5x3 m. The soil of the orchard is loamy Haplic Luvisol with the following parameters: pHKCl - 5.8, organic matter content - 2.8%, available phosphorus - 383 mg/kg, exchange potassium -120 mg/kg, alkali-hydrolysable nitrogen - 108 mg/kg. Experimental scheme: 1. Control (no fertilizers); 2. N30К40; 3. N60К80; 4. N90K120; 5. N120K160. Fertilizers were applied once a year in early spring. The annual use of fertilizers in N90K120 dose or more contributed to an increase in the reserves of mobile phosphorus, exchange potassium, and alkali-hydrolysable nitrogen in the orchard soil, but did not have a stable effect on the tree productivity. At the same time, there was an increase of soil acidity and loss of exchange calcium under the influence of fertilizers, which indicates the beginning of degradation processes.

“…Most of the territories of the Kuban-Azov lowland, located in conditions of insufficient and unstable moisture, are characterized by a lack of water resources for use in agricultural production, which leads to the forced use of irrigation water that is not suitable for irrigation. The use of mineralized water in drip irrigation systems, along with a positive effect on the productivity of fruit plants [15], often contributes to the degradation of irrigated chernozem soils [16].…”

The scientific and practical problems of deterioration of the soil fertility of apple tree plantations under drip irrigation with mineralized waters are discussed. A significant decrease in soil biodiversity was revealed, depending on the duration of cultivation of fruit plantations. A prerequisite for biologization is an objective assessment of the availability of soil nutrients under droppers, which will reduce the load on the environment as a result of the rational use of fertilizers. The necessity of biologization of garden farming and reduction of soil fatigue is actualized. The ways of solving the problem of soil fatigue and reducing the fertility of chernozem soils in fruit plantations of areas of forced use of drip irrigation with mineralized waters are outlined.
