Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite.

Plant availability was highest for bone char produced between 300 C and 500 C in three acidic soils from three continents, and declined rapidly above 750 C. This strongly indicated that crystallinity of hydroxyapatite limits plant availability at high pyrolysis temperatures.

Phosphorus (P) is the second essential macro nutrient for crops after nitrogen. It plays an important role in several biochemical processes of plants. The available quantity of phosphorus in most native soils is low, which is present in forms that are quite unavailable to plants (Esther, 2019; Mary et al., 2020).
