firmer grip than clay.

This fact gives us a hint as to how we may improve the sand and clay.

Organic matter mixed with these soils by applying manures or plowing
under green crops will cause the sand to hold the rain better and the
clay to absorb it more readily.




CHAPTER V

FORMS OF SOIL WATER


Water which comes to the soil and is absorbed exists in the soil
principally in two forms: Free water and capillary water.


FREE WATER

Free water is that form of water which fills our wells, is found in
the bottoms of holes dug in the ground during wet seasons and is often
found standing on the surface of the soil after heavy or long
continued rains. It is sometimes called ground water or standing water
and flows under the influence of gravity.

Is free water good for the roots of farm plants? If we remember how
the root takes its food and moisture, namely through the delicate root
