Worldwide most soils and crops require phosphorus P additions to improve fertility and production Directly applying unprocessed phosphate rock to soil may provide a valuable source of plant nutrients in specific conditions but growers must consider several complicating factors and limitations Rock Phosphate is a sedimentary rock composed of phosphate minerals high enough especially apatite It is used directly in fertilizer and as a source of phosphorous compounds Apatite includes 10 mineral species and has the general formula X 5 Y PO 4 3 where X is usually Ca 2 or Pb 3 and Y is F Cl or OH
