    Rock Phosphate: an organic source of phosphorus Rock phosphate is found in all continents of the world (figure 1) It is used as a raw material in the manufacture of inorganic phosphorus fertilizers and can be used as organic phosphorus fertilizers when applied directly to the soil Direct application of rock phosphateRock phosphate at the rate of 1,000 pounds per acre was mixed throughout the soil Plants with high cation exchange root systems (ragweed and smartweed) were more effective in obtaining phosphorus from soil and rock phosphate for themselves, and were two to three times as effective as the lower exchange root systems (Lamb's quarters and wheatSolubilization of Soil and Rock Phosphate as Related toApatite is the most abundant phosphate mineral which include more than 95% of al phosphorus in the Earth´s crust The seventh chapter of this book provides brief description of sedimentary and igneous phosphate rocks and introduces basic ideas for characterization and classification of phosphate rocks The chapter continues with description of biogenic apatites, description of phosphatePhosphate Rocks | IntechOpen

  • Phosphorite an overview | ScienceDirect Topics

    Phosphate rock or phosphorites are minerals that contain phosphorus (P), measured by its phosphorus pentoxide (P2 O 5) content at elevated concentrations In phosphate ore the concentrations of P 2 O 5 usually range from 5–25% To be marketed the P 2 O 5 is concentrated to roughly 30%Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize In the past, rock phosphate was used alone as a fertilizer, but due to a lack in supply, as well asHow is rock phosphate made? – KitchenMonocalcium phosphate, the major portion of superphosphate, is watersoluble Dicalcium phosphate is largely citratesoluble Rock phosphate has low citratesoluble P and very low watersoluble P P Fertilizers Rock Phosphate: source of allPhosphorus University of Wisconsin–Madison
