Impact of Climate Change on Soil Health and Nutrient Cycling: Implications for Sustainable Agriculture

Abstract

Climate change is one of the greatest environmental challenges facing agriculture today. Rising global temperatures, irregular rainfall, prolonged droughts, and extreme weather events have significantly influenced soil properties, microbial activity, and nutrient cycling. These alterations threaten soil health, reduce agricultural productivity, and endanger global food security. This article explores how climate change affects the physical, chemical, and biological components of soil health, including organic matter, soil structure, microbial diversity, and nutrient dynamics. It also evaluates the implications of these changes on sustainable agriculture and presents adaptive and mitigative strategies to maintain soil fertility under changing climates. Integrating climate-smart agricultural practices such as conservation tillage, biochar application, organic amendments, and microbial inoculants is emphasized as a pathway to sustain soil functions. The paper concludes by highlighting the necessity of holistic, ecosystem-based management approaches that combine traditional knowledge with modern technologies for achieving climate-resilient and sustainable agriculture.
