Reclamation status of irrigated grass-alluvial soils based on geoinformation systems in Uzbekistan

Abstract

The utilization of geoinformation technologies in evaluating soil cover degradation presents a revolutionary approach to understanding and mitigating the adverse effects of environmental decline. The article underscores the criticality of such technologies in conducting comprehensive analyses that can pinpoint the multifaceted impacts of degradation processes on soil health. Through the detailed examination of salinity levels, mechanical composition, humus content and reserves, as well as the quantities of mobile phosphorus and exchangeable potassium within the top 30 cm layer of soil, geoinformation technologies offer unparalleled precision and scope in environmental assessment. Specifically, the study focuses on the Khorezm Massif of the Amudarya District and the Kamisharyk Massif of the Chimboy District in the Republic of Karakalpakstan (both in Uzbekistan), where the impact of irrigation on meadow soils was scrutinized. By leveraging a variety of thematic maps crafted with the latest in geoinformation system (GIS) tools, researchers were able to deliver a granular view of the soil reclamation status across these areas. This methodical approach not only enhances our understanding of soil degradation patterns but also facilitates the development of targeted strategies for soil conservation and sustainable management. In essence, geoinformation technologies serve as a critical asset in environmental science, enabling researchers to navigate the complex interplay between human activities and the natural landscape. Through the meticulous analysis of soil characteristics across impacted regions, these technologies pave the way for informed decision-making and the implementation of effective soil reclamation and protection measures, thereby contributing to the resilience and sustainability of vital agricultural and natural ecosystems.
