Types of Soil - Clay ,Sandy , Loam Video Lecture - Class 7

here is from nothing done you gonna make
me genius back up did you I see more
science videos go to WWE Pete genius
that girl real it is free so you're
wondering what is happening in pot -
you've put in water you've put in
fertilizer and nutrients but why is this
plant not growing do you know what the
reason could be let me explain it to you
it depends upon the soil in the pot did
you know the growth of plants depends
upon four things okay don't worry let me
tell you they are the amount of sunlight
availability of water availability of
air and the amount of nutrients so now
you know four important requirements for
plants to grow but do you know soil is
also responsible for points two three
and four
okay so let's learn why soil plays a
very important role for plant growth or
how why the plant in pot one is growing
and the plant in pot two is not growing
is linked to the soil in the pots so
there are two different types of soils
in these two pots the soil in pot one is
good for plant growth and the soil in
pot two is not good for plant growth the
soil in pot 1 helps plants to get water
nutrients and air but in pot - the soil
is not good for these three things but
let me first explain the different types
of soils
do you know different types of soils
okay there are three types of soils clay
sandy and loam you see these three jars
all of these jars have different types
of soils let us learn about these three
types
the first one is clay the soil particles
are very small and very close to each
other there is some space in between
particles and it can hold a lot of water
but very little air let's put some water
in each jar now take soil from jar
number one into your hand grab it in
your hand tightly now open your hand see
how the clay soil holds itself tightly
and doesn't break so it is tightly
packed and holds the water now see jar -
it is sandy soil its particles are
bigger in size and further away from
each other there is a lot of space among
particles water passes through these
pores and does not stay in the soil for
very long now take some soil in your
hand from this jar
try to form a ball now open your hand
see it crumbles it does not hold any
water so for plants it is not good in
deserts very few plants are able to grow
due to this reason
now this soil in jar number three is
loam soil it is a mixture of sand and
clay soil it is best for plants as it
holds water air and nutrients very well
now try to make a ball from this soil
it crumbles but it still holds together
so now you understand three types of
soils so you're going to

it also has lots of interesting facts in
