Soil Fertility and Earthworms: Enhancing Agricultural Sustainability through Biological Activity

Soil fertility is a critical component for sustainable agricultural productivity, influenced by physical, chemical, and biological factors. Among soil biota, earthworms play a pivotal role in enhancing soil fertility through their burrowing, feeding, and casting activities. This article reviews the multifaceted contributions of earthworms to soil health, focusing on nutrient cycling, soil structure improvement, and microbial interactions. Earthworm activity promotes nutrient mineralization, organic matter decomposition, and soil aggregation, leading to increased availability of nitrogen, phosphorus, and other essential nutrients for plants. The ecological functions of earthworms as ecosystem engineers and their synergistic relationships with soil microorganisms underscore their importance in agroecosystem management. Understanding these processes can inform sustainable agricultural practices that optimize earthworm populations and thereby improve soil fertility and crop yields
