Soil is very important, if we didn't have soil we wouldn't be able to survive (nothing would actually).

Here in NC our community is mostly farmers, so if we had infertile soil we would be very economically unstable.

Soil in NC

The type of soil we have here in NC is cecil soil.

It is very ferial and is good for growing crops.

Soil Conservation

One way to help conserve soil is by planting legumes, theses plants , such as peanuts, alfalfa and beans, all help replenish the soil. THey change nitrogen into a form that plants can use.
