Agrochemical characteristics of soils in the vicinity of the village of Mishkino, Mishkinsky district of the Republic of Bashkortostan

Abstract

The article is devoted to the analysis of the dynamics of the content of such important elements of fertility as phosphorus and potassium and the acidity of arable soils in the vicinity of the Mishkino Mishkinsky district of the Republic of Bashkortostan is determined. The data on the content of phosphorus and potassium and the determination of acidity in the soils of the Mishkinsky district of the Republic of Bashkortostan from 1976 to 2000 were compared. Studies on the phosphorus content in the soils of the Mishkino district conducted in 1976 showed an average level of phosphorus availability. Studies conducted in 1992 showed a slight increase in the availability of phosphorus in the soil. Studies in 2015 and 2020 showed a continuing trend of increasing the availability of phosphorus in the soil. Studies conducted to study the potassium content showed a fairly low potassium content in 1976. In 1992, in general, there were changes in the classes of security and in the amount of potassium content in the soil. Studies in 2015 and 2020 showed a steady trend towards an increase in potassium content in the soils of the district and the presence of soils only with an increased and high potassium content. Studies on soil acidity conducted in 1976 showed that the area of arable soils is mainly represented by medium-acid and slightly acidic soils. Studies in 1992 showed an increase in soil acidity. In the following years, the farm undertook methods of agrochemical effects on soils in order to reduce acidity. Research 2015. and 2020 showed a significant decrease in the acidity of arable soils. It has been established that due to the use of methods of rational nature management of territories, the area of agricultural soils with an average and increased content of mobile phosphorus and exchangeable potassium increases, processes of neutralization of strongly acidic soils occur.
