Dec 13, 2016· 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 phosphate increases crop yield and soil phosphorus levels (1, 2,3)
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is For example, ammonium nitrate has a specific gravity (sg) of 073 while dry ammonium sulphate has a sg of 113 (1130 kilograms/cubic meter)
