Various calcium phosphate minerals, which often are not white owing to impurities, are used in the production of phosphoric acid and fertilizers. Overuse of certain forms of calcium phosphate can lead to nutrient -containing surface runoff and subsequent adverse effects upon receiving waters such as algal blooms and eutrophication (over ...
Bone meal provides phosphorus and calcium to plants, along with a largely inconsequential amount of nitrogen. [4] The N-P-K rating of bone meal is typically 3–15–0 [5] along with a calcium content of around 12% (18% CaO equiv.), [6] although it can vary quite a bit depending on the source from 1–13–0 to 3–22–0.
Hydroxyapatite (IMA name: hydroxylapatite [5]) (Hap, HAp, or HA) is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), often written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. [6]

The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition. [7]
Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca 10 ( PO 4 ) 6 (OH,F,Cl) 2 , and the crystal unit cell formulae of the ...
Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. [1] Plants are able to absorb essential elements through their leaves. [ 2 ] The absorption takes place through their stomata and also through their epidermis .
The main component of bone is hydroxyapatite as well as amorphous forms of calcium phosphate, possibly including carbonate. Hydroxyapatite is the main component of tooth enamel. Water fluoridation enhances the resistance of teeth to decay by the partial conversion of this mineral to the still harder material fluorapatite: [17] Ca 5 (PO 4) 3 OH ...
