Question

presentation about minerals riches in the soil i will give a paragraph take the important points and make a presentation.
As you have seen, soil is a mixture. It
contains small particles of rock (of different
sizes). It also contains bits of decayed living
organisms which is called humus. In addition,
soil also contains various forms of
microscopic life. The type of soil is decided
by the average size of particles found in it
and the quality of the soil is decided by the
amount of humus and the microscopic
organisms found in it. Humus is a major
factor in deciding the soil structure because
it causes the soil to become more porous and
allows water and air to penetrate deep
underground. The mineral nutrients that are
found in a particular soil depends on the
rocks it was formed from. The nutrient
content of a soil, the amount of humus
present in it and the depth of the soil aresome of the factors that decide which plants
will thrive on that soil. Thus, the topmost
layer of the soil that contains humus and
living organisms in addition to the soil
particles is called the topsoil. The quality of
the topsoil is an important factor that decides
biodiversity in that area.
Modern farming practices involve the use
of large amounts of fertilizers and pesticides.
Use of these substances over long periods of
time can destroy the soil structure by killing
the soil micro-organisms that recycle
nutrients in the soil. It also kills the
Earthworms which are instrumental in
making the rich humus. Fertile soil can
quickly be turned barren if sustainable
practices are not followed. Removal of useful
components from the soil and addition of
other substances, which adversely affect the
fertility of the soil and kill the diversity of
organisms that live in it, is called soil pollution.
The soil that we see today in one place
has been created over a very long period of
time. However, some of the factors that
created the soil in the first place and brought
the soil to that place may be responsible for
the removal of the soil too. The fine particles
of soil may be carried away by flowing water
or wind. If all the soil gets washed away and
the rocks underneath are exposed, we have
lost a valuable resource because very little
will grow on the rock.The roots of plants have an important role
in preventing soil erosion. The large-scale
deforestation that is happening all over the
world not only destroys biodiversity, it also
leads to soil erosion. Topsoil that is bare of
vegetation, is likely to be removed very
quickly. And this is accelerated in hilly or
mountainous regions. This process of soil
erosion is very difficult to reverse. Vegetative
cover on the ground has a role to play in the
percolation of water into the deeper
layers too.
