GULLY MODELING FOR FOREST RECLAMATION PURPOSES
- Land Reclamation, Recultivation, and Land Protection
The aim of research was to study the properties of sierozemic-meadow soils formed as a result of polluted water irrigation and to find the location of these soils in the WRB international classification system. The object of the study is sierozemic-meadow soils, which are continuously irrigated with muddy water that brings 2000–4000 kg per ha of water-soluble salts. Groundwater lies at a depth of 2–3 m. The investigated plot is located on the territory of the Ujar main base, which is in the central part of the Shirvan plain. A morphological description was made for five soil sections, and soil samples were taken horizontally in which the granulometric composition, the content of water-soluble salts, and the composition of the soil absorbing complex were analyzed. Morphodiagnostic indicators of sierozemic-meadow soils have been changed as a result of prolonged anthropogenic impact. An irrigation horizon of 75–90 cm is formed in them. They are characterized by different granulometric composition. The number of particles > 0.01 mm varies within the range of 11.6–70.8 %. In these soils, the total amount of carbonates varies from 10–18 %, humus in the range 1.73–7.94 %, the sum of the absorbed bases is 10.72–36.84 mmol(eq)/100 g, and pH is 7,9–8.5. In the genetic layers of sierozem-meadow soils there is a process of accumulation of salts, including carbonates. The gleying process is observed in horizont B of seirozemic-meadow soils developing under hydromorphic conditions. Irrigated sierozemic-meadow type of soils in which the irrigation and gleyed horizons were formed as a result of intense anthropogenic action can be attributed to the Anthrosols group in the international soil classification system. Because of the secondary accumulation of carbonates, these soils are classified as Calsis, and by the influence of groundwater as Gleyic. From the additional qualifiers, there are diagnostic signs such as salic, endosalic, clayic/loamic, fluvic.
