Composting in the Yard
As more cities and local communities place restrictions on disposal of yard
wastes, composting becomes an excellent option for many homeowners. If you have
always thought that composting was too much work or too smelly, maybe it is time
to reconsider this backyard conservation practice!
You do not need special equipment to start a compost pile. Simply piling yard
debris in a heap on the ground will work, but it will be a slow process. This is
referred to as cold composting. No specific amount of material is needed to
start the compost heap, and you can add to the pile at anytime. You can run a
lawnmower over small piles of weeds and clippings to help shred them. Do not use
a lawnmower to shred woody materials! While cold composting is the simplest
method, it also is the slowest. Some studies have shown that because of the low
temperatures achieved during decomposition, weed seeds and disease causing
organisms may not be destroyed.
Hot composting causes the material to decompose faster. It also has the
benefits of destroying many weed seeds and disease organisms. For hot
composting, a pile with minimum dimensions of 3’ x 3’ x 3’ is needed for
efficient heating. Moisture and aeration are required.
Many styles of compost bins are on the market that will help contain the pile
and hasten the process. Some resemble garbage cans. The new material is placed
in the top and the finished compost can be scooped out of the bottom. Other bins
are spherical and as you roll the bin, the compost is mixed and aerated. You can
build a simple bin. A hoop of wire mesh will contain the waste and allow air to
enter from all sides. Wooden bins also can be built--numerous plans are
available from nurseries or garden centers. Check on local regulations before
building a compost bin. Some urban areas require rodent proof bins.
- Here are some tips for successful composting:
- Choose a level, well-drained site, preferably near your garden.
- For hot composting, mix together or alternate layers of green materials
such as grass clippings and brown materials such as dead leaves. Green
materials provide a source of nitrogen while leaves provide carbon for the
decomposing organisms.
- A small amount of nitrogen fertilizer or barnyard manure can be added if
needed to supply nitrogen.
- Keep the pile moist, but not wet. Soggy piles encourage the growth of
organisms that can survive without oxygen and cause unpleasant odors.
- Provide aeration either by turning the pile or by using bins that allow
air to enter the pile.
- Do not compost pet manure that can contain diseases or meat scraps that
can attract unwanted insects or wildlife.
- Be patient. Composting is not an exact science. The rate of decomposition
will vary depending on weather conditions and materials composted. Finished
compost will be pleasant smelling and crumbly to the touch. It can be used
in any garden and will provide nutrients for plants and help improve the
structure of the soil.
