Transcript a comparative study between the ability of different types of legumes

The Introduction
Prepared by: Gab Macas
The earth’s atmosphere is made up
of 78% nitrogen and it is essential to
healthy
plant
growth.
Without
nitrogen, green plant are weak and
smaller than they should be.
Nitrogen helps our plants to build
protein, but although nitrogen is
already available in the air, plants are
unable to utilize nitrogen directly.
Legumes are members of
the pea or bean family.
Some legumes are capable
of providing a readilyavailable source of nitrogen
to our soil.
Legumes
have
rhyzobium
bacteria in their root nodules.
These bacteria are able to take
nitrogen
directly
from
the
atmosphere and fix it into the
soil, this is due to the mutuality
symbiotic
relationship
with
bacteria found in some legume
plants.

Main problem:
◦ What type of legume plant fixes more nitrogen into
the soil?

Sub problem
◦ Is there any significant difference between the
different types of legumes in terms of:
 Nitrogen fixation into the soil
 Fertility of the soil after the legume plant fix nitrogen
into the it?
 There
is no significant
difference between the ability
of different types of legumes
in fixating nitrogen in the
atmosphere to the soil.
To know what kind of legume fixes
more nitrogen in the atmosphere
into the soil
 To know how fertile is the soil after
the nitrogen in the atmosphere fixes
into the soil by laboratory soiltesting or in a practical way such as
repetitive planting


For me and my co-students
◦ This study will give us additional knowledge in
agricultural matters.

For the farmers
◦ This study will give them an alternative way in
making soil fertilizer.

For legume plant consumers
◦ This study will help some of them to have an extra
income due to the soil that they used in planting
their legume plant.
This study was conducted in _______________
for ______ days during the academic school
2011-2012 at the researchers' residences.
This study is limited only in knowing which
type of legume fixes more nitrogen in the
atmosphere into the soil. It will not go further
such as quantifying the amount of nitrogen
that is present in the soil.
