Soil Quality Attributes and their Contribution to Plant Growth and Productivity: A Comprehensive Review

Soil quality and its chemico-physical characteristics are fundamental determinants of soil fertility, plant productivity and biosphere sustainability. This review brings together existing research on how the physical and chemical characteristics of soil affect plant growth by integrating information from classical soil science literature and recent regional investigations. The review discusses the processes of soil formation and highlights how soil texture, structure, bulk density, porosity, moisture, hydraulic conductivity, temperature and other physical attributes regulate water availability, aeration and root development. The review further explores the influence of major soil chemical properties, such as pH, electrical conductivity, organic carbon content, cation exchange capacity and nutrient availability, on nutrient cycling, microbial functioning and the nutritional status of plants. Particular emphasis is placed on the interactions among these properties, demonstrating that soil functions are governed by their combined rather than isolated effects. Recent advances in soil assessment techniques, including standardized laboratory analysis, GIS, remote sensing, digital soil mapping and precision agriculture, are reviewed as valuable tools for evaluating spatial variability and supporting informed soil management. The review also emphasizes sustainable soil management approaches, including conservation agriculture, integrated nutrient management, organic amendments, balanced fertilization, crop rotation, efficient water management and soil conservation for maintaining soil health and improving agricultural productivity. Finally, existing research gaps are identified, including the need for integrated assessment of biological, physical and chemical soil indicators, long lasting monitoring and climate-resilient soil management strategies. Overall, the review emphasizes that maintaining balanced soil physicochemical characteristics through scientific assessment and sustainable management is crucial for enhancing plant growth, conserving soil resources and securing long life agricultural and ecological conservation.
