A scientifically based system of fertilizers and chemical soil reclamation

The research was carried out in the agricultural production cooperative SEC “Ural” in the Askinsky district of the Republic of Bashkortostan, where soil samples became the object of research. According to the data obtained from the agrochemical analysis, the following quantitative indicators were obtained: the weighted average indicator of soil humus content was 4.1–7.6%, the weighted average indicator of mobile phosphorus content was 34-130 mg/kg of soil, and exchangeable potassium was 51.1 mg/kg of soil. The potassium balance was 16-113 mg/kg of soil. The pH of the aqueous extract of the soil ranged from 4.5 to 5.7, i.e. it varied from strongly acidic to neutral.
