Abstract

The 40K radioisotope is involved into the erosion processes on the arable slopes. Application of the very high resolution satellite images, GISs, geomorphometry methods and traditional agrochemical research techniques helped to identify the location of areas on the concave parts of the slopes, where 40K radioactivity in the soil is increased; and location of areas on the convex parts, where 40K radioactivity is low. High content of humus or high content of clay fractions in the soil can cause increase of the radioisotope content. The application prospects are shown for all abovementioned methods in study of the 40K isotope lateral distribution in the soils of agrocenoses.

Keywords
