METHODOLOGICAL APPROACHES TO MAPPING THE CONTENT OF HUMUS USING REMOTE SENSING DATA

Abstract

The author developed a technique for mapping the quantitative content of humus from remote sensing data of the earth. In this work, the author used data from high-spatial resolution satellite resources and 3 test sites located in the Minsk and Baranovichi regions of the Republic of Belarus. Sod-podzolic soils of varying degrees of hydromorphicity and granulometric composition are characteristic of the studied areas. During the field work, 240 soil samples were selected and an analysis was carried out for the content of humus, according to Tyurin's method. Agrochemical soil analysis data were compared with data of optical brightness on cosmic images. As a result of the statistical analysis, high values of the determination coefficients for all the investigated fields were obtained, which makes it possible to use the spectral characteristics to obtain data on the intrinsic unevenness of the humus content.
