The textbook describes methods for analyzing the elemental composition of the mineral part of soils, ways to express the results of gross analysis and recalculation of analytical data. Methods for studying the ion-salt complex of soils and available forms of plant nutrition elements, as well as methods used to determine the total humus and nitrogen, group and fractional composition of humus, and methods for studying some properties of humic acids are presented. The use of gross analysis data, the results of studying the ion-salt complex and soil organic matter for practical purposes is considered. Meets the requirements of the federal state educational standards of higher education of the latest generation. It is addressed to students of higher educational institutions studying at the faculties of soil Science, agrochemistry and ecology in the field of training "Agrochemistry and agro-soil science", as well as graduate students and researchers specializing in soil science, agrochemistry, ecology and agronomy.
