Please note it should be buried deeply when fertilize. Journal of Environmental Science 21, 575–580. The products produced are dust-free and of such particle size that they are well suited for bulk blends. Therefore, the process pH should be kept below the precipitation limit. Ad. Seed selection is important for both process effectiveness and reusability of the recovered materials. Economical and with high nutrient content, ammoniated phosphates such as mono- and di-ammonium phosphate (MAP, DAP) are another popular choice of fertilizers. As the drum rotates, pieces of the solid fertilizer take on small spherical shapes. After the spring bloom, the nitrogen concentration increases because of local remineralisation of ammonium and the eventual nitrification that leads to an accumulation of unutilized nitrate. The solubility curve separates the undersaturated condition from the supersaturated condition (metastable, nucleation, and precipitation). Finally, control of fluorapatite particle size (from 15 nm to 200 μm) and morphology can be achieved by varying precipitation conditions using aqueous precipitation from a micro‐emulsion or by biomimetic synthesis in a gelatin matrix [129]. It serves for the output increase as well as quality improvement. showed that for the same fluoride level supplied, the precipitation of fluorapatite using an organic phosphate source (phosphate ester monomer) instead of an inorganic phosphate source led to higher fluoride contents [127].
