Fertilizers possess extraordinary physical properties that may cause problems during its production, handling, application chain, storage, and transportation. Problems such as caking and lumping, moisture uptake and dust problems can occur due to unstable granules.
Currently, coatings are used to patch up the physical properties of fertilizer types with poor base quality. Many coatings consist of petroleum-derived polymers and waxes, or polymers that are not biodegradable.
