“…After heavy July rains, a significant decrease in potassium levels was observed in August. Studies previously conducted in this field experiment have shown the possibility of potassium leaching into deeper soil layers [17]. In 2020, all doses of potassium fertilizers used in the experiment contributed to a significant increase in the content of exchangeable potassium.…”

The study was conducted to assess the impact of mineral fertilizers applied to the soil on the potassium level in the components of the “soil-plant” system of the sour cherry orchard. The experiment was conducted in the forest-steppe zone of the Central Russian Upland (Orel region) on loamy Haplic Luvisol during 2018-2020. The seasonal dynamics of exchangeable potassiumin the soil, the potassium status and productivity of sour cherry trees cv. ‘Turgenevka’ on the rootstock V-2-180 were studied in the orchard of 2015 planting. Fertilizers in the form of (NH2)2CO and K2SO4 were applied annually in early spring in doses of N30K40, N60K80, N90K120 and N120K160. It was found that a significant decrease in the level of potassium in the soil occurred during the period of intensive growth and crop formation, or after heavy precipitation. The use of fertilizers increased the content of exchangeable potassium in the soil (by 1.2-2.2 times), while the features of the potassium dynamics observed in unfertilized plots were preserved. Fertilizers contributed to the annual improvement of the potassium status of the leaves (by 0.05-0.24 % DW). The positive effect of fertilizers on the potassium content in fruits and the productivity of trees was manifested only in a year with prolonged intense precipitation (2020). The potassium content in fruits was 1.12-1.16 times higher than the control when applying N30K40, N60K80 and N90K120. A significant increase of tree productivity was found when applying N60K80 and N120K160 (by 54 and 69%, respectively).

The article presents long-term data on studying domestic plum varieties in an intensive garden. The study was conducted to determine the effect of leaf nutrition on the yield and quality of plums. Counts and observations were carried out in 2019–2021 on the site of the irrigated garden of the Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences. In this place, experience was laid in growing fruit trees. The garden was founded in 2014. The planting pattern is 5.0 m × 2.0 m. The research objects were the plum varieties Kubanskaya Spring, Renclad Altana, and Burbank; the study subjects were complex fertilizers Master, Aquarin, Ultramag Boron, and Ultramag Calcium. The studies were carried out on six typical trees of each variety in triplicate. The experimental data were processed using the variance analysis method according to B.A. Dospehov. The program and methodology for studying fruit, berry, and nut crops included accounts and observations. The highest yield was noted for the Burbank plum variety - 12.1 t/ha. Foliar feeding with complex fertilizer in the version using the drugs Aquarin, Ultramag Boron, and Ultramag Calcium provided the maximum average increase in yield. Among the studied varieties, the enormous weight and size of the fruit were found in the Kubanskaya Spring variety, which amounted to 55.2 g in the variant with the use of complex fertilizers Aquarin and Ultramag Bor together with Ultramag Calcium. Using foliar fertilizing with fertilizers containing macro- and microelements allows you to regulate fruiting quality
