What are Fertilizers? Materials used to increase plant growth,
production, and increase health. Six primary Nutrients
Nitrogen Phosphorus Potassium Sulfur Magnesium Calcium
How does it Relate? All fertilizers are composed of elements,
compounds, or polyatomic ions Nitrogen – NH4 NO3 CH4N2O (Urea) Phosphorus – minerals containing PO4
-3
Potassium – K20 (Potash) KCl KSO4-2
Sulfur - SO4-2
Magnesium – MgO MgSO4-2
Calcium – CaCO3 Ca3(PO4)2
Relationship to Organic Chemistry Definition of Organic Chemistry:
The chemistry of carbon compounds (other than simple salts such as carbonates, oxides, and carbides).
What are Carbon Compounds? Compounds (a combination of elements)
containing carbon
Nitrogen Gives plants a dark
green color Required in the
largest quantities Allows
photosynthesis to occur at higher rates
Phosphorus Promotes root growth Hastens maturity Important to cell division and plant
growth
Potassium Improves drought resistance Assists fruit growth Regulates CO2 uptake
Sulfur Provides a direct nutritive value Provides indirect nutritive value as soil
amendments Improves the use efficiency of other
essential plant nutrients, particularly nitrogen and phosphorus
Magnesium Increases resistance to disease Serves as the building block of
chlorophyll A deficiency turns leaves yellow
Calcium Strengthens a plant’s cell walls Helps to neutralize naturally occurring
acids inside of the plant Plants deficient in calcium first show
stunted growth in new leaves and roots
pH Regulators Lime – CaO
Raises pH Applied to acidic
soils Neutralizing
effects Commonly found
in biosolids
Aluminum Sulfate – AlSO4
-2
Lowers pH Applied to basic soils Used to neutralize Other pH-lowering
substances exist
Joke Why did someone apply Aluminum
Sulfate to a sorority house? Because they wanted them to stop being
basic
