Water stability of structure of arable soils of Ukraine

Abstract

Goal. To construct a map of water resistance of the structure of arable soils of Ukraine and to determine the area of soils with improved, average and deteriorated indicators. Methods. Selection of data from the "Properties of Soils of Ukraine" database, their processing and map construction. Results Area of arable soils with improved water resistance of the structure occupy about 14% of arable land, or 4.2 million hectares, the average - respectively 32.4% and 9.7, deteriorated - 27.8% and 8.4 million hectares. Other areas occupy conditionally unstructured sandy and sandy soils and soils for which water resistance measurements were not measured. Conclusions Water resistance of the structure as a highly informative soil quality indicator should be included in the list of monitoring indicators, and the soil area with its various indicators should become the object for the use of differentiated structurally-preserving measures.
