Besides hydroxyapatite (HA) being utilized in bioengineering because it is similar to the component of bone and teeth, HA is also optimized as a fertilizer and a coating seed to deliver micro and macronutrients. The other benefits are to provide the phosphorus element for supporting the growth of a plant and to avoid depleting the P element in soil. HA can be obtained from natural waste (shells and bone) that have to be treated by various methods. One of them is the wet precipitation method which results in many products and just needs an organic solvent.
