GENESIS AND EVOLUTION OF THE SOIL AND REGIONALIZED CROP PLANTS IN THE LOWER REACHES OF AMU DARYA REGION, UZBEKISTAN.

The presented manuscript deals with the issues of genesis and evolution of soil structure and crop plants in the Lower Amu Darya Region. The pertinent investigation also elaborates on wild plant characteristics in the desert zone and details of cultivated plants grown in the Lower Amu Darya region. The paper also discusses soil-forming processes and the structure of soils, which is the external appearance involved in specific changes from the vertical direction of its layers. Horizons always differ in color, structure, composition, and other morphological features. The article also describes the mechanical composition of the soils of these regions, including the formation of plants grown on highly saline soils, the morphology and characteristics of these plants, and the effective use of arable land to ensure food security in the country. Likewise, the most urgent problems today are increasing soil productivity and its protection and raising economic efficiency to obtain high-quality and ecologically clean products from every agricultural crop. The soils distributed in the lower Amudarya regions, including Karakalpakstan and Khorezm regions, are more or less saline. For the soils' future effective use, salt-resistant and phytomeliorative crops, especially alfalfa, white corn, beets, melons, watermelons, and pumpkins, and oil crops, such as sesame, will give a high and highquality harvest. As a result of the sand and dust-salty mixture rising from the dry bottom of the Aral Sea under the influence of the wind in the spring months, crops are drying up. Therefore, to prevent this, it is most practical and scientifically imperative to carry out phytomeliorative work in these areas to establish saxovull farms. [ABSTRACT FROM AUTHOR]
