Complex inorganic powders based on calcium phosphates have found a plethora of practical applications. Of particular interest are the CaO-P2O5 system-based multi-component material powders and granules as the source of major- and micronutrients for the plants. The emerging strategy is to use nano fertilizers based on hydroxyapatite (HAP) for phosphorus and other nutrient delivery. The doping of micronutrients into HAP structure presents an interesting challenge in obtaining specific phase compositions of these calcium phosphates. Various techniques, including mechanochemical synthesis, have been employed to fabricate doped HAP. Mechanochemical synthesis is of particular interest in this review since it presents a relatively simple, scalable, and cost-effective method of calcium phosphate powder processing. The method involves the use of mechanical force to promote chemical reactions and create nanometric powders. This technique has been successfully applied to produce HAP nanoparticles alone, and HAP doped with other elements, such as zinc and magnesium. Nanofertilizers developed through mechanochemical synthesis can offer several advantages over conventional fertilizers. Their nanoscale size allows for rapid absorption and controlled release of nutrients, which leads to improved nutrient uptake efficiency by plants. Furthermore, the tailored properties of HAP-based nano fertilizers, such as controlled porosity and degradation levels, contribute to their effectiveness in providing plant nutrition.

“…In recent years, hydroxyapatite (HAP) emerged as a tunable P-release fertilizer material. [6][7][8][9][10] The use of HAP as a tunable P-fertilizer, particularly in nanoparticulate form, offers advantages such as environmental stability and reduced soil acidication risk. 11,12 Importantly, P release from HAP particles can be tuned by altering their particle size and surface charge properties, thus providing opportunities for designing multifunctional fertilizers, not only for major (N, P, and K) but also for minor (Cu, Zn, Mo, and others) nutrient delivery, according to the needs of specic soil and crop types.…”
