INTRODUCTION (abstract of PhD thesis)
(abstract of Doctor of Philosophy (PhD) dissertation)
The aim of the study is remote sensing of the effect of the Kattakurgan reservoir on the surrounding soil research pare and its transformation and development of scientific recommendations for effective use of them in agriculture by creating thematic maps with the help of GIS programs.
The object of the research work study is virgin, rainfed and irrigated typical serozem, medow-serozem, serozem-meadow and meadow soils, distributed in the territory of the Kattakurgan reservoir in the Samarkand region.
The subject of stuy…
The scientific novelty of the research is as follows:
the formation of medow-serozem, serozem-meadow and meadow soils was determined as a result of the transition of virgin, rainfed and irrigated typical serozems from automorphic regime to semi-hydromorphic and hydromorphic regimes;
a schematic map of the soils adjacent to the Kattakurgan reservoir has been compiled according to typical serozem, meadow-serozem, serozem-meadow and meadow groups of soils, formed depending on the moisture regime and evolution of the soils of the territory;
a map of soil moisture adjacent to the Kattakurgan reservoir on a scale of 1:25000 has been developed, linking moisture processes with dynamic changes in groundwater in the territory based on the schematic map of soils adjacent to the Kattakurgan reservoir.
The practical results of the research are as follows…
The implementation of the research results. Based on the scientific results obtained on the current state of typical serozem soils distributed in the territory of the Kattakurgan reservoir, and their impact on the reservoir:
a map of the current state of moisture of typical serozem soils distributed in the territory of the Kattakurgan reservoir was compiled on a scale of 1:25.000 on a total area of 77,747 hectares and put into practice as a recommendation for increasing the efficiency of agriculture (Reference of the Ministry of Agriculture No. 02/022-5072 dated December 14, 2021). As a result, they made it possible to scientifically increase the fertility and productivity of automorphic rainfed serozem soils, as well as the placement of agricultural (cereals, oilseeds and legumes) crops and the implementation of systematic agrotechnical measures in order to regularly increase their productivity;
the group and quantity of soils formed around the Kattakurgan reservoir were determined, and recommendations aimed at increasing soil fertility were put into practice (Reference of the Ministry of Agriculture No. 02/022-5072 dated December 14, 2021). As a result, they made it possible to develop intensive gardening through drip irrigation, the development of perennial tree plantations and forestry through moisture conservation in order to use semi-automorphic rainfed typical serozem soils, as well as semi-hydromorphic virgin meadow soils in agriculture;
recommendations for the use of virgin and rainfed soils of the Nurabad region, in the moisture map on a scale 1: 25000, compiled for the territory of the Kattakurgan reservoir, have been put into practice (Reference of the Ministry of Agriculture No. 02/022-5072 dated December 14, 2021). As a result, they made it possible to effectively use virgin and rainfed lands for growing feed in livestock farming and medicinal plants in forestry.
