Abstract

A multifactorial mathematical model has been developed, which allows the preliminary evaluation of the humus horizon thickness based on the values of the Normalized Difference Vegetation Index (NDVI) and terrain slopes. Based on this model, the soil map of the agricultural lands of the company "Rustas" was refined, covering an area of 3,377.85 ha. As a result of improving the soil map on the lands of SRL "Rustas," the following distribution of soil areas was identified: ordinary chernozems – 2,777.33 ha (73.60%), of which slightly eroded – 121.59 ha (3.22%), moderately eroded – 14.05 ha (0.37%), strongly eroded – 8.16 ha (0.24%); carbonatic chernozems – 404.61 ha (10.72%), of which slightly eroded – 133.08 ha (3.53%), moderately eroded – 30.59 ha (0.81%), strongly eroded – 10.73 ha (0.32%); floodplain groundwater-wet soils – 80.75 ha (2.14%) and alluvial soils – 192.66 ha (5.11%). The integrated approach, combining remote sensing and field determination of the humus horizon thickness, can be applied for the preliminary evaluation of soil erosion intensity. The research results facilitate the work of pedologists in conducting soil studies.
