Soil microbiology delves into the diverse world of soil-dwelling microorganisms and their ecological functions. These microbes, including bacteria, fungi, and protozoa, are pivotal in nutrient cycling, organic matter decomposition, and supporting plant growth. The text celebrates Sergei Winogradsky's contributions and explores the synergy between soil microbiology, ecology, and biochemistry in maintaining healthy ecosystems.
