“…According to various researchers, apples should contain at least 5... 14 mg of calcium per 100 g of fresh weight so as not to be affected by bitter pits [2,15,16]. The first fruits of 'Sinap orlovsky' obtained in 2016 on the third year after orchard planting at the highest level of soil calcium contained calcium in the amount of 10.19 ± 0.83 mg/100 g FW (experimental average).…”

The experiment was carried out to study the relationship between the soil calcium conditions and the content of this element in fruit and leaves of apple trees at ground fertilization with nitrogen and potassium. The experimental orchard is located in the forest-steppe zone of the Central Russian Upland (Oryol region). The soil of the orchard is Loamy haplic luvisol with a slightly acidic reaction and a high content of organic matter. Fruit plantations are represented by apple trees of ‘Sinap orlovsky’ variety on rootstock 54-118 planted in 2013. Ammonium nitrate and potassium chloride were used as soil fertilizers and applied early in spring at doses of N30K40, N60K80 and N90K120. Annually from 2016 to 2019, the content of exchangeable and water-soluble Ca compounds in the orchard soil and the total element content in leaves and fruits were determined. With the annual application of nitrogen and potash fertilizers the changes in the conditions of apple tree calcium nutrition occured already in the first years after treatments. The changes lay in increasing the calcium mobility and subsequent decrease in the element’s concentration in the root zone. At the same time, there was an annual decrease in the calcium status of fruits. The Ca content in fruits was positively correlated with the content in the soil of exchange (r = 0.43; P<0.05) and water-soluble (r = 0.51; P<0.01) forms of the element. There was no statistically significant relationship between the studied soil calcium forms and element content in apple leaves.

“…Содержание калия в плодах повышалось под влиянием обработок до оптимального уровня Кальций улучшает функциональную деятельность мембран и снижает развитие заболеваний при хранении (в т.ч. горькой ямчатости), замедляет процесс старения плодов [13]. Более высокая кратность применения агрохимиката УЛЬТРАМАГ КАЛЬЦИЙ в варианте Система 1 обеспечила и более высокое содержание кальция в плодах.…”

влияние некорневых подкормок на формирование некоторых компонентов продуктивности яблони. Изучено содержание азота, фосфора, калия и кальция в листьях и плодах яблони под действием агрохимикатов АО «Щелково Агрохим». Проведена оценка влияния различных систем некорневых подкормок, составленных из агрохимикатов АО «Щелково Агрохим», на минеральный состав листьев и плодов, а также урожайность деревьев яблони в условиях интенсивного сада. Отмечено позитивное влияние таких агрохимикатов как Биостим универсал, Ультрамаг калий, Ультрамаг кальций, а также микроэлементов в хелатной форме. Ключевые слова: некорневые подкормки, хелатные соединения, урожайность, содержание элементов питания в листьях и плодах яблони. Summary. The infl uence of foliar fertilizing on the development of certain components of apple tree productivity is presented. The content of nitrogen, phosphorus, potassium and calcium in the leaves and fruits was studied under the action of agrochemicals of Shchelkovo Agrokhim JSC. There is done the evaluation of impact of various foliar fertilizing systems, composed of Shchelkovo Agrokhim JSC agrochemicals on the mineral composition of leaves and fruits as well as on the yield of apple trees in an intensive orchard. There is marked positive effect of such agrochemicals as Biostim universal, Ultramag potassium, Ultramag calcium, as well as microelements in chelate form.
