Determination of resistance parameters for soil of agricultural lands to droughts and compilation of digital maps of the spatial distribution of the identified factors (for example of the Kamenetsk region)

Abstract

The developed scale for grouping the main types of Belarus soils according to the degree of resistance to droughts and arid phenomena, depending on soil-hydrological constants, granulometric composition of soils and underlying rock (resistance parameters) presents at the article. Based on the created digital maps of resistance parameters, as well as the developed scale of soil resistance, a cartographic material was created in the QGIS software environment reflecting the distribution of soils of the Kamenetsk region by groups of resistance to droughts and drought events. It has been established that the soil cover of the Kamenetsk region is characterized by a high potential risk of droughts and arid phenomena. The proportion of the least and weakly resistant soils in the total area of the region is 62,9 % and 41,0 % of agricultural land. It has been established that the soils least resistant to droughts and arid phenomena belong to the non-agricultural land.
