1a)
Experiment to compare the porosity and
water holding capacity
1b)
Grind loam and clay soil into fine particles,
after drying in the sun. Equal masses of
the dry, dry clay and dry loam are place
seperately into three funnels which are
blocked at the neck with cotton wool. The
three funnels containing different types of
soil are then placed on top of the three
measuring cylinders. Then quickly pour
equal amount of water into the funnels,
containing each soil type. Then leave for
an hour
1c)
i)Loamy
ii)Sandy
iii)Clay
1d)
i)I will ensure th three funnels containing
different types of soil are placed on top of
the three measuring cylinders
ii)I will ensure equal amount of water is
quickly poured into the funnels containing
th soil type
1e)
-sandy soil
Because the porosity is high in sandy soil
because of large pores spaces and larger
particles sizes
