Soil physico-chemical dynamics, microbial diversity and productivity responses in agroforestry system

Abstract

Agroforestry systems play a crucial role in enhancing soil physico-chemical properties, nutrient dynamics, microbial diversity, and overall productivity, contributing to sustainable land management. Tree - based systems improve soil structure, organic carbon content, nutrient retention, and water-holding capacity through litterfall, root turnover, and microclimatic modifications. Soil nutrients exhibit spatial and temporal variability influenced by tree and crop interactions, topography, and seasonal changes, forming nutrient - rich zones that optimize crop and tree growth. Microbial communities, along with enzymatic activities, regulate nutrient cycling, soil organic carbon stabilization, and biological health, supporting long - term fertility and ecosystem resilience. Agroforestry also contributes to carbon sequestration, climate - change mitigation, and enhancement of ecosystem services. Integrating soil assessment data into management strategies enables early detection of soil constraints such as acidity, salinity, and nutrient deficiencies, allowing corrective interventions. These insights support climate-smart agroforestry planning, sustainable productivity, and the long - term health and resilience of agroecosystems.
