Аннотация
The paper considers the use of Sentinel 2 (S2) optical data for 2019-2020 to assess the content of humus, clay and moisture in the upper (0-10 cm) soil layer on the example of chernozems and gray forest soils of the Novosibirsk region. Special attention is paid to the selection of satellite images, it is necessary to meet the conditions for the soil to be dry and bare. The humus content was estimated for five test sites based on a regression model [1] and S2 spectral band B6 (740 nm). The model parameters were adjusted for the conditions of the study area separately for chernozems and gray forest soils. The clay content in the soil was estimated using S2 optical data, ground-based measurements, and regression models with an exponential dependence of the clay content on the reflection coefficients from the soil at the SWIR channels of S2 ([2],[3]). The change in the percentage of humus and clay content in the test sites soils per the year is shown.
