Method of Mapping and Classification of Eroided Land in Azerbaijan
Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 3, Issue 2
Abstract
In the conditions of Azerbaijan, erosion, causing erosion, erosion and deflation of soils, has developed a great deal. It is most distinctly expressed on soils cultivated in conditions of rain fed agriculture that are not secured and semi-provided with rainfalls. In order to solve the problems of rational use of lands subject to erosion or potentially erosion-hazardous, it is necessary to deeply understand each land mass of the farm, its features that can influence the choice of crops for those or other general measures, or private methods of agricultural technology. Obtaining such data is possible only as a result of large-scale surveys of the territory. Depending on the degree of loss of the upper horizons of the soil, usually very weak, medium, strong and very strongly eroded soil differences are isolated. The more the soils are eroded, the more they differ from their non-washed analogues in chemical, granulometric composition and physico-chemical properties, water, air and heat regimes, biogenicity and other indicators, the aggregate of which affects fertility and their erosion resistance. The nature of the changes in the granulometric composition of soils during the development of erosion is mainly determined by the degree of its homogeneity in the depth of the profile. If the soils are fertile, then undiluted and washed-out varieties are few by this feature. In the washed-out soil, the silt fraction is markedly reduced. In eroded soils, the mineralogical composition of the arable changes in connection with its change in the depth of the soil profile. Very large changes in the granulometric and mineralogical composition are observed on strongly washed soils.
