Immobilization in soil science is that the conversion of inorganic compounds to organic compounds by micro-organisms or plants, by which it's prevented from being accessible to plants. Immobilization is that the opposite of mineralization where the inorganic nutrients are haunted by soil microbes making them unavailable for plant uptake. The immobilization process is a biological process controlled by bacteria that consume inorganic nitrogen and for, amino acids and biological macromolecules (inorganic forms). Immobilization and mineralization happen continuously and concurrently whereby nitrogen of the decomposing system is transformed steadily from inorganic to the organic state by immobilization and back from organic to the inorganic state by decay and mineralization.
