Soil pH is crucial to soil health, influencing nutrient availability, microbial activity, and plant growth. This review aims assess the adaptability of under changing conditions by analyzing natural human factors. Information was gathered from various sources, including peer-reviewed articles, field studies, recent advances in science. The study explores how factors such as parent material, climate, vegetation establish baseline pH, while activities intensive farming land-use changes further modify it, often leading acidification or alkalinization. Traditional management methods like lime application, organic amendments, crop rotation are reviewed for their effectiveness stabilizing limitations varying conditions. also modern technological innovations precision agriculture, which uses sensors variable rate technology targeted management, biological approaches, inoculants, enhance cycling matter decomposition. Integrating these traditional contemporary approaches essential sustainable long-term productivity. findings highlight need a holistic approach that combines historical knowledge with emerging technologies promote agricultural practices environmental conservation.
