Types of Soil Video Lecture | Basic Science for JSS 3

depending upon the tight on the amount
of particles present in the soil it is
of three types sandy soils clay soil and
lowly soil
sandy soil is Grace brown in color it
has large particles which allow air and
water to pass through it this soil
cannot hold water sandy soil is found on
the beaches and riverbanks
clay soil is brown in color it has very
fine particles which stick together it
can hold a lot of water plants light
rice that need lot of water grow well in
this soil
clean soil is found near the river mouth
loamy soil is a mixture of sand clay and
lots of humors the soil retains some
water and lets the extra water pass
through completely
it is the best soil for the growth of
plants loamy soil is found in planes and
platoon
Activity one take three pots with holes
at the bottom place each of them on two
bricks take three small pieces of cotton
cloth and spread them at the bottom of
each pot the holes at the bottom of pots
should be completely covered
take equal amount of sandy clay and
loamy soils and put them in pots
separately
keep a small beaker under the whole of
each pot as shown
now for equal amount of water in each
pot
note the amount of water collected in
each beaker note which soil has maximum
water holding capacity
you will find that clay soil can hold
maximum water as very little water is
collected in the beaker
sandy soil hoods minimum water as much
water is collected in the beaker
