PRELIMINARY AGROCHEMICAL INDICATORS OF THE EXPERIMENTAL FIELD

Abstract

This article studies the initial agrochemical analysis of the experimental field when applying potash fertilizer forms to sunflower crops. To perform this analysis, soil samples were taken from the arable and subarable layers of the soil before plowing the experimental field. In addition, a section was dug to determine the general morphological characteristics of the soil and the elements in individual layers. Individual layers of the soil profile were measured, identified, and samples were taken from each of them and analyzed. The obtained soil samples were taken to the State Enterprise “SoilQualityAnalysis” for analysis, where an initial agrochemical analysis of the experimental field was determined from the soil samples. During the analysis, analyses were also performed on the salinity level and pH of the soil, as well as on the absorption capacity of the soil. According to the results of the study, the topsoil and subsoil layers of the experimental field were not saline, while weak signs of salinity were observed in the parent rock. The elements Ca, Mg, K, and Na were studied in terms of soil absorption.
