The K3CaH (PO4)2 and possibly CaKPO4 phases formed provide a better nutrient management of P, K and Ca, when applied in soil system the material first release K and form hydroxyapatite and important P and Ca bioavailable source at pH  5, which comprises a large part of many countries soils.  aEggshell  aKH2PO4  aPotassium calcium phosphates  aSmart fertilizer1 aGIROTO, A.
