Role of Microorganisms in Soil Fertility and Plant Health

Abstract

The intricate relationship between microorganisms, soil fertility, and plant health is a pivotal aspect of sustainable agriculture and ecosystem functioning. This abstract provides a concise overview of the essential contributions made by microorganisms to soil fertility and the promotion of plant well-being. Microorganisms, including bacteria, fungi, archaea, and other microbes, play multifaceted roles in soil ecosystems. One of their primary functions is nutrient cycling, where they break down organic matter into essential nutrients, making them available for plant uptake. Nitrogen-fixing bacteria, for instance, convert atmospheric nitrogen into a form usable by plants, fostering their growth and development. Furthermore, microorganisms contribute to soil structure and stability through the secretion of extracellular substances. This enhances water retention, aeration, and nutrient availability, creating an optimal environment for plant roots. Mycorrhizal fungi form symbiotic associations with plant roots, facilitating the exchange of nutrients and enhancing the plant's resistance to diseases and environmental stresses.
