“…It is known that with regular use of potassium fertilizers, the content of exchangeable potassium gradually increases and subsequently stabilizes at a certain level specific to a particular soil [11]. The rate of accumulation of exchangeable potassium compounds in the orchard soil depended on the doses of fertilizers.…”

“…Stone fruit trees, including cherry, have a variable need for potassium during the growing season. Reserves of exchange compounds are the main source for stabilizing the potassium level in the soil solution when plants uptake the element [11]. The study of the dynamics of soil potassium in combination with the determination of the potassium status of cherry trees can be useful for improving the diagnosis of potash nutrition and improving the effectiveness of potassium fertilizers.…”

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).

“…При недостатке доступного фосфора замедляется синтез белков, возрастает содержание нитратного азота в тканях растений [13]. При недостатке калия задерживается синтез белка и накапливается небелковый азот [5,14]. Поэтому своевременное удовлетворение потребности растений в фосфоре и калии -одно из главных условий формирования их высокой урожайности, а содержание (фосфора и калия) относится к числу основных показателей, которые используют при оценке состояния почвенного покрова [15].…”

The change in the content of mobile phosphorus and exchangeable potassium in calcic chernozem of the Rostov region has been studied. The use of chisel treatment on an erosion-hazardous slope reduced soil flushing by 12.6%. By the end of the first rotation of the grain-to-crop crop rotation, when using an extensive fertilizer application system, a decrease in the content of mobile phosphorus and exchangeable potassium was noted. Over the seven rotations of the crop rotation, this difference continued to increase. Systematic application of fertilizers in various doses allowed to increase the content of mobile phosphorus by 145.1-151.6%, exchangeable potassium - 21.1-24.1% compared to the initial content. Tillage had a negligible effect on the content of mobile forms of plant nutrition elements. Keywords: CALCIC CHERNOZEM, MOBILE PHOSPHORUS, EXCHANGEABLE POTASSIUM, CROP ROTATION, LONG-TERM EXPERIENCE
