Like clay itself, clay soils are:
· impermeable.
When it rains on a clay soil the water does not go through the soil easily. The water takes a long time to disappear. You can see the mud. So clay soils are
· difficult to work.
Wet clay sticks to the hands. It also sticks to tools.
For
this reason clay soils are very difficult to work after the rains.
Clay soils
are called heavy soils.
During the dry season clay soils become very hard.
Cracks form in them.
The lumps are difficult to break.
Water remains in the soil; Cracks
form in the soil
Soils with much clay are difficult to work and are often too
wet.
Soils with little clay are easily carried away by water and by the
wind.
