Abstract

Recent investigations are focused on the characterization of hydroxyapatite nanoparticles obtained via addition or substitution processes with different cations or molecules. These nanoparticles can be used for developing fertilizers that can be applied in sustainable agriculture. Hydroxyapatite (HA) has multiple uses in agriculture: as a source of phosphorus, to obtain slow-release fertilizers as well as for removing and / or immobilizing heavy metals. Synthesised hydroxyapatite (HAE) gives the advantage of using a phosphorus source without elements that can cause soil, water and plant pollution. The experiments were carried out in vegetation pots and the results exhibited a 6% yield increase in wheat biomass after hydroxyapatite application compared to the unfertilized control.
