Description
Soil fertility: Is the ability of the soil to supply elements/nutrients essential for plant growth (From germination to physiological maturity) without toxic concentration of any element i.e. in the required amount and at the required time.
Soil productivity: Is the ability of the soil to produce a particular crop or sequence of crops under a specified management system.
NB: Productive soils are fertile for the crops being grown. However, many fertile soils are unproductive because they have poor climate.

BIOCHEMISTRY
Polyurethanes are prepared from diisocyanates
and diols. Urethane (also called a carbamate) is a
functional group that contains both an ester and an
amide at a single carbonyl group.
Nucleophilic Addition Reaction: Example 1:
Sevin is a highly effective, biodegradable insecticide. It
affects the nervous systems of insects by blocking
access to the neurotransmitter acetylcholine.

PETROLEUM CHEMISTRY
Carbon is so Important in the Life Cycle. It has
numerous ways of bonding with many other
elements, particularly oxygen and hydrogen.
It can form both “organic” and “inorganic”
compounds. Organic compounds are considered
unstable in the biosphere because they are in the
reduced state.
Whereas Inorganic compounds, principally
calcite (CaCO3
) and dolomite (CaMg(CO3
)2
), are
stable because they are in the oxidized state.
Carbon is present in most substances that are
vital for the development of life (called
“biomolecules”): Proteins, lipids, sacharides, etc

BIOCHEMISTRY
Alkyl halides are organic molecules containing a halogen
atom bonded to an sp3 hybridized carbon atom.
• Alkyl halides are classified as primary (1°), secondary (2°),
or tertiary (3°), depending on the number of carbons bonded
to the carbon with the halogen atom.
• The halogen atom in halides is often denoted by the symbol
“X”.

Natural Gas
Natural gas is a gaseous fossil fuel consisting
primarily of methane but including significant
quantities of ethane, butane, propane, carbon
dioxide, nitrogen, helium and hydrogen sulfide.
Obtained from oil fields and natural gas fields,
and in coal beds.
Methane-rich gases are produced by the
anaerobic decay of non-fossil organic material, ie
biogas.
Total world production of natural gas in 1986
was 100 trillion m3
.
It is used as feed stock as well as fuel. It is
preferred due to its high Calorific Value
