The key difference between organic and inorganic sulfur is that organic sulfur refers to the sulfur present in organic compounds, which is highly immobile in the soil, whereas inorganic sulfur refers to the sulfur present in inorganic compounds, which is highly mobile in the soil.
Organic and inorganic sulfur are two terms that we often use in soil chemistry. Sulfur can occur in soil in two forms as organic and inorganic sulfur, depending on the type of compound to which the sulfur atoms are attached. These sulfur-containing compounds circulate through soil systems via different methods such as mobilization, immobilization, mineralization, oxidation and reduction.
