FERTILIZER
INDUSTRY
Fertilizer -any material of natural or synthetic
origin that is applied to soils or to
plant tissues
(usually leaves)
to supply
one or more
plant nutrient
s essential
to the growth of plants and yielding
the crop of fruits.
Nutrients Needed:
✓ Natural Nutrients
(e.g Carbon,
Hydrogen, and Oxygen)
✓ Primary Nutrients (e.g Nitrogen,
Phosphorus, Potassium)
✓ Secondary Nutrients (e.g Ca, Na, S,
Mg)
✓ Micronutrients (Copper, Molybdenum,
Cobalt)
natural fertilizer = organic fertilizer
synthetic fertilizer = chemical fertilizer
HOW DOES FERTILIZER ARISE?
1) EGYPTIANS
added ashes from burned weeds to soil.
2) ANCIENT GREEK AND ROMANS
added animal excretory to the soil.
3) JOHANN GLAUBER
developed the first complete mineral fertilizer,
which was a mixture of saltpeter, lime,
phosphoric acid, nitrogen, and potash
4) JUSTUS VON LIEBIG
demonstrated that plants need mineral elements
such as nitrogen and phosphorous in order to
grow.
5) JOHN LAWES
outlined a method for producing a form of
phosphate that was an effective fertilizer.
-invented artificial fertilizer when he discovered
superphosphates, his name for the combination
of rock phosphate with sulfuric acid
6) FRITZ HABER
synthesis of ammonia from its elements,
hydrogen and nitrogen, earned him the 1918
Nobel Prize in Chemistry
