Soil fertility is often measured mainly through macronutrients like nitrogen (N), phosphorus (P), and potassium (K), while the biological processes that make these nutrients available are frequently overlooked. Soil microorganisms act as a “living nutrient engine,” unlocking nutrients that may otherwise remain tied up in organic matter, microbial biomass, or mineral bonds in the soil. Without strong biological activity, many nutrients, including nitrogen, phosphorus, and micronutrients, remain unavailable to plants, and organic residues decompose slowly, which can sometimes be observed in fields where crop residues persist for several years.
