Soil microorganisms are vital for nutrient cycling as they decompose organic matter, releasing essential nutrients back into the soil. This process facilitates the availability of macro and micronutrients, enabling plants to absorb them for growth. Microorganisms also play a role in enhancing soil structure, promoting water retention, and creating habitats for other soil organisms. Moreover, they contribute to soil fertility and sustainability, ultimately supporting healthy plant ecosystems. Their presence is essential for maintaining the overall health of terrestrial ecosystems.
