Abstract
The study was conducted in order to study the effect of mineral fertilizers on the dynamics of nutrition elements and strawberry yields on chernozem soils in the central part of the East European Plain. The work was carried out in 2022-2023 in the conditions of the central part of the East European Plain. The scheme of the field experience involved the study of the following options: economic control (Controlfit RK + Crystallon (15-5-30-4MdO+micro)); AQUARIN 1 N-P-K+Mg+S+Me7-11-30+4+3+ Me with a daily rate of 15 kg/ha; AQUARIN 14 N-P-K+Mg+S+Me 20-20-20+1,7+1,5+ Me with a daily rate of 10 kg/ha. The humus content in the 0...20 cm soil layer of the experimental site was 4.85% (according to Tyurin), mobile phosphorus and potassium (according to Machigin) - 88.8 and 49 mg/kg, respectively, NH4 – 4.98 mg/kg, pH of the soil solution – 5.5 units. As a result of the conducted studies, a variant using AQUARIN 14 N-P-K+Mg+S+Me 20-20-20+1,7+1,5+ Me, increased the content of mineral nitrogen, mobile phosphorus and exchangeable potassium in relation to economic control and AQUARIN 1 N-P-K+Mg+S+Me 7-11-30+4+3+Me, by 2.2 – 4.9; 1.5 – 2.2 and 0.3 – 1.4 mg/kg of soil, respectively. The maximum yield in the experiment was fixed on the variant using AQUARIN 14 N-P-K+Mg+S+Me 20-20-20+1,7+1,5+ The Me significantly exceeded the control indicators by 2.3 t/ha. The difference between the experimental variants was 1.6 – 2.3 t/ha.
