  2. 2. | The Manufacturing Process  Fertilizers are composed of several solid chemical compounds. To make the fertilizer easy to use, each of these compounds must be formed into grains. One method of forming these materials is to put them into a rotating drum. As the drum rotates pieces of solid fertilizer takes on small circular shapes. Next the small pieces pass through a screen, which separates out the sized particles. After, a coating of inert dust is applied to the particles. The will dust keep the particles from sticking to each other. Then, the particles are dried. But when the components are granulated they are mixed together producing a composite fertilizer. The finished fertilizer is loaded into a hopper, which releases a designated amount into large bags. The bags are sealed closed and are shipped.

  4. 4. Raw Materials  Chemical Fertilizers: Fertilizers are named after 3 numbers, such as 6-12-12, which means, 6 percent nitrogen, 12 percent phosphorus oxide, and 12 percent potassium oxide. The elements found in chemical fertilizers are usually from rocks and minerals.
  5. 5. Main Uses  Fertilizer is used as a substance added to soil to improve plant’s growth. The fertilizer helps restore food elements to the soil, to help with growth of the plants.
  6. 6. Waste products  Fluoride is a waste product of phosphate fertilizer. At the phosphate industry they capture all the fluoride gases.
  7. 7. Safety  They are tested in agriculture laboratories, like the U of S agriculture department and, independent studies.
