The soil metabolome is the complete set of small molecules or metabolites present in soil. These metabolites can include a wide range of compounds such as sugars, amino acids, organic acids, and secondary metabolites. Understanding the soil metabolome can provide valuable insights into the complex interactions between soil microorganisms, plants, and other organisms in the soil ecosystem. Analyzing the soil metabolome can help researchers better understand nutrient cycling, plant-microbe interactions, and overall soil health. This field of research is relatively new but holds great potential for advancing our understanding of soil biology and ecology.
