Fractal–Geomorphological Controls On Soil Cover Formation, Particle Size Distribution, And Agroecological Functioning Across River Basin Landscapes

Dr. Aleksandr M. Petrov — Thu, 01 Jan 2026 00:00:00 +0000

Soil cover formation within river basin landscapes represents the integrated outcome of sedimentary processes, geomorphological evolution, hydrological regimes, and long-term anthropogenic management. Contemporary soil science increasingly recognizes that soil properties cannot be fully understood without accounting for spatial heterogeneity generated by microrelief, river terraces, floodplain dynamics, and land reclamation practices. This study presents a comprehensive theoretical and analytical synthesis of soil particle size distribution, soil cover ecological state, and agrophysical functioning across diverse geomorphological settings at the river basin scale. Drawing strictly on the referenced scholarly corpus, the article elaborates the conceptual significance of fractal dimension approaches to particle size distribution, the geomorphological controls exerted by river terraces and floodplains, and the modifying influence of microrelief on hydrothermal soil regimes. Special attention is given to alluvial and solonetzic soil complexes, irrigation-induced transformations, and the role of leguminous and fodder crops in altering soil agrophysical and agrochemical properties. The methodology is grounded in text-based comparative analysis, interpretive synthesis of sedimentological and ecological soil indicators, and conceptual extrapolation of empirical findings presented in the cited literature. Results are discussed in descriptive terms, emphasizing patterns of spatial differentiation, ecological stability, and functional resilience of soils under varying natural and managed conditions. The discussion critically evaluates theoretical implications, addresses limitations inherent in scale-dependent soil analysis, and outlines future research directions integrating fractal theory, geomorphology, and sustainable land management. The article contributes a unified academic framework for understanding soil cover dynamics as a complex, multi-scalar system shaped by both natural processes and human intervention, with implications for ecological assessment, irrigation planning, and agroecosystem sustainability.

This article analyzes the changes in plant height and heritability index (hp) in F1 hybrid generations of durum wheat studied in the research conducted in 2025 at the “Durum Wheat Genetics, Breeding and Seed Production” laboratory of the Lalmikor Agricultural Research Institute. The results of the study made it possible to identify promising combinations for selection work and determine the genetic advantages of parental forms. The positive or negative heritability index reflected the degree of dominant influence of parental plants in hybrids.

Reducing Soil Salinity In Cotton Cultivation Through Biofertilizers

Shamshetova Nilufar Maratovna — Fri, 16 Jan 2026 00:00:00 +0000

Soil salinity is one of the most persistent constraints affecting cotton productivity in arid and semi-arid regions, particularly under irrigated agricultural systems. Excessive accumulation of soluble salts in the root zone disrupts soil structure, limits water and nutrient uptake, and weakens plant physiological processes, ultimately leading to significant yield reductions. In recent years, biofertilizers have gained increasing attention as an environmentally sustainable alternative to conventional chemical inputs for salinity management. This article provides an in-depth analytical review of the role of biofertilizers in reducing soil salinity in cotton cultivation. Special emphasis is placed on the biological mechanisms through which beneficial microorganisms improve soil aggregation, regulate sodium toxicity, enhance rhizosphere activity, and strengthen plant tolerance to salinity stress. Furthermore, the synergistic effects of biofertilizers when combined with organic amendments and modern irrigation practices are critically examined. The analysis demonstrates that biofertilizer-based approaches not only contribute to the gradual desalinization of soils but also promote long-term soil fertility, ecological stability, and sustainable cotton production.
