| 1. A good soil
for growing plants should generally
contain about 50% pore space
and 50% solids. The pore space
should consist of half air and
half water, and the solids should
be made up mostly of minerals
(sand, silt, and clay particles)
mixed with some organic matter. |
|
| 2. In the soil,
air and water are found within
the pore spaces between the
particles. If this ideal soil
were dried out, and all the
pore space were compressed so
that there was no more air and
no more space, all that would
remain would be the solid portion
of the soil. |
