Secondary nutrients in phosphate rock. Among the significant chemical and nutritional constraints on crop growth on acid soils are deficiencies of calcium (Ca) and magnesium (Mg) nutrients. As the apatite mineral in PR is CaP, there is a potential to provide Ca nutrient if there are favourable conditions for apatite dissolution.
