Abstract

Electrophysical research methods are widely used in countries with developed agricultural production for the purpose of soil monitoring and surveys. One of these methods of research is determining the electrical conductivity of the soil. Because with the help of this indicator, it is relevant to clarify the boundaries of soil differences, which makes it possible to use it in precision agriculture. Thus, the purpose of the article is to compare the changes in the electrophysical parameters of typical chernozem under different fertilization systems under conditions of drip irrigation. In order to carry out the analysis, individual soil samples were taken for each year of research in the period 2018-2020 in the spring (May) before the start of strawberry flowering. From the selected and air-dried soil samples using the quarting method, average mixed samples were selected for analysis. It was concluded that electrophysical indicators undergo changes according to the depth of sampling, which is related to the assimilation of useful substances from the soil by plants and fertilization mechanisms and correlates to a significant extent with the acid-alkaline indicators of the soil. A three-year study (2018-2020) of the influence of different fertilization systems under drip irrigation conditions on the electrophysical parameters of typical chernozem during the cultivation of garden strawberries was conducted. It was established that the greatest changes in electrophysical indicators (electrical conductivity, general mineralization, salinity) of typical chernozem occur from the ridge part to a depth of 20-30 cm. The difference in the obtained values of electrophysical indicators between variants of different fertilization of typical chernozem (control, mineral system, organo-mineral system, organic system), as well as during years of research
