Soil health refers to the biological, chemical, and physical features of soil that are essential to long-term, sustainable agricultural productivity with minimal environmental impact. Thus, soil health provides an overall picture of soil functionality. Although it cannot be measured directly, soil health can be inferred by measuring specific soil properties (e.g. organic matter content) and by observing soil status (e.g. fertility). There is also increased interest in studying soil microorganisms in their particular environments, as microbial diversity and biomass are intimately related to soil structure and function. One of the key indicators for soil health is denitrification as it is completely done by soil microorganisms and enzymatic activity. The denitrification process, which reduces nitrate and nitrite to nitric oxide (NO), nitrous oxide (N2O), and dinitrogen (N2), is an important indicator of soil health and N-cycling transformation. It is the only pathway, except for the process of anaerobic ammonium oxidation (Anammox), by which reactive forms of nitrogen (Nr) in terrestrial and aquatic ecosystems are transformed back into inert N2gas.
