Soil microbiomes are communities of microorganisms, including bacteria, fungi, and archaea, that live in the soil. These tiny organisms play a crucial role in nutrient cycling, breaking down organic matter, and supporting plant growth. They help improve soil structure and fertility, making them essential for healthy ecosystems and agriculture. The composition of a soil microbiome can vary based on factors like climate, land use, and soil type. Understanding these communities is important for sustainable farming practices and environmental conservation, as they influence soil health and the overall productivity of agricultural systems.
