Experiment to compare the porosity and water
holding capacity

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

(i) I will ensure the 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 the
soil type
