No2a
Advantages
u can tabulate if u want
i) Reduces Greenhouse Effect: It also reduces
the greenhouse effect by utilizing the gases
being produced in landfills as forms of energy.
This is a major reason why the use of biogas
has started catching on.
ii)Non-Polluting: It is also considered to be
non-polluting in nature. The production of
biogas does not require oxygen, which means
that resources are conserved by not using any
further fuel.
Disadvantages
i) Not Attractive on Large Scale: The process
of using biogas on a large scale is not
economically viable and it is very difficult to
enhance the efficiency of biogas systems.
ii) Unstable: It is also somewhat unstable,
making it prone to explosions if the methane
comes in contact with oxygen and become
flammable in nature.

Denitrification is the process
of releasing nitrogen back
into the atmosphere.
its also the biological conversion of nitrate to
nitrogen gas, nitric oxide or nitrous
oxide. These compounds are gaseous compounds
and are not readily available for
microbial growth; therefore they are typically
released to the atmosphere. Nitrogen gas
makes up over 70% of atmospheric gases, thus the
release of N2 to the atmosphere is
benign.
[10:18AM, 5/6/2015] idode paul abel: 2e)Mineral Matter.
The mineral matter represents small rock
fragments of the soil. It forms the bulk of
about 45% of total volume of the soil. It
consists of gravel, stones, sand, silt and
clay.
Importance/effects of Mineral matter on
Agriculture
(i) It forms the solid part of the soil which
provide support for plants
(ii) Mineral matter is the main source of
plants nutrients such as Nitrogen, Calcium,
Magnesium, Iron etc.
(iii) It represents the home of all soil living
organisms.
(iv) It holds water and air for both plant
and animal activities.
ii) Organic Matter
The organic matter represents the remains
of the decomposition of plants and
animals. It is about 5% of the total volume
of the soil. Leaves, roots of plants, the
residue of crops, animal dung etc when
they are deposited on the soil decay to
form a dark colour on the upper part of
soil to form organic matter also called
humus.
Importance/effects of Organic Matter on
Agriculture
(i) It is very rich in plant nutrients.
(ii) It is the habitat of many soil micro-
organisms.
(iii) It is the leaching in soil where it is
present in adequate amount.
(iv) It also prevents soil erosion and
evaporation.

Differentiate between land
ownership by
leasehold and land
ownership by freehold
1.Freehold- means the
occupier/purchaser owns the property and usually
the land on which it
stands for an unlimited
period of time - freehold
confers the absolute right
to ownership of property and land to the
owner of the property.
2.Leasehold- means a
person owns a property
(but not the land on which
that property stands) for a set period of time,
usually in return for a
rent of some kind. At the
end of that period (the
length of the lease) the
property reverts back to the freehold owner (who
may also be referred to
as the landlord).
