There are several kinds of land, for example:
cultivated land the fields that are farmed;
cultivable land
fields that can be farmed only if they are cleared;
land that cannot be
farmed, because nothing grows on it; you cannot farm stone or laterite.
WHAT IS THE LAND LIKE IN YOUR VILLAGE?
In your village maybe a hole has been dug, in order to make a
well, or to get earth to make bricks.
Or maybe a ditch has been dug between
two fields.
Let us dig a hole ourselves.
Let us dig it deep, and quite
straight.
What do we see?
The soil is made up of different kinds of
earth, of different layers.
These layers
· are not of the same colour; that on top is often darker.
· are not of the same depth.
By making a hole you can see the
layers of soil
· In the first layer we find
roots; this is the soil.
The soil is the layer of earth where roots find
their food.
The soil is more or less deep.
The soil is more or less rich
in food.
· Below the soil is a harder
layer.
It is difficult to make a hole in it.
This is the subsoil.
· Even deeper is rock, called the parent rock.
Sometimes you can very clearly see the difference between two
layers.
Sometimes the layers are alike.
You cannot see the difference very
clearly.
Good land: it has deep
soil
