  10. (Essential nutrients) Micro nutrients
    needed in small amounts (7)

    -Fe, Zn...
  11. Whats in a fertilizer?

    ex) 6:12:6, 6% N, 12% P, 6% K .
  12. How do you apply the fertilizer? (3)
    depends on...

    -time of year

    -age of plant

    -concentration (how much)
  13. 2 types of fertilizers

  14. (types of fertilizers) Inorganic; Chemicals (5)
    -powders, liquids, "sticks"

    -easier to use


    -doesnt smell

    -may only have 3 nutrients (N, P, K )
  15. (types of fertilizers) Organic (5)
    -from living things




    -can have all essential nutrients

    ex) cow manure, bat guano, blood neal, sewage sludge
