PHOSPHATE ROCK (FERTILIZER) '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 .
