Renewable and Nonrenewable Resources
There are many types of resources that go into producing food and producing forages
In general these resources have been grouped into two types, renewable resources and
nonrenewable resources. Renewable resources may be defined as resources that have the
potential to be replaced over time by natural processes. The renewal process may be
relatively quick, as with sunshine which comes on a daily basis. Or, the renewal process
may be very slow, as in the formation of soil which may take hundreds of years.
Nonrenewable resources may be defined as resources whose stock or reserves is limited
or fixed. The available supply of nonrenewable resources may be replenished through
recycling (e.g. recycling aluminum cans), but the overall supply remains relatively constant.
The table below gives several examples of each type of resource.
