Compost
Composting might bring to mind thoughts of a
pile of rotting organic matter and nothing much more to
you.
Composting is simply decomposition of organic
material. Bacteria, fungi, nematodes, worms,
and microscopic organisms use organic matter in their
own life cycle, and in the process break it down. This is
naturally a slow process but there are things we can do to move
it along.
quality compost will provide nutrients and humus to the
soilas well as improving water holding capacity. It encourages
the formation of beneficial organisms and makes
the soil nutrients readily useable.
What are the basic elements of composting?
The organic waste can be placed on bare earth or mixed in
with soil if on a hard non organic surface. Healthy
compost piles do not attract undesirable pests and do not emit
excessive odors but a location somewhat out of site and travel
areas might be advisable.
Some sort of containing walls are helpful but not essential.
You may require several partitions for compost at various
stages from raw unprocessed to nearly ready for use.
Anything that is bio-degradeable is suitable for composting.
that opens the door to most yard waste and household food
wastes.
The properties of the two primary elements for a good
compost include high carbon materials and high nitrogen
materials. The ideal carbon to nitrogen ratio (C/N) for
stimulating the composting organisms is 25:1 - 30:1. Finished
compost is 14:1 - 20:1. This means little to you and I but
leads to types of materials required.
High carbon materials are comparable to fiber for humans.
Common examples are hay, straw, fall leaves, sawdust, pine
needles. The C/N ratio varies from 500:1 for sawdust to 12:1
for alfalfa hay.
High nitrogen materials include manures, grass clippings,
table scraps, cottonseed meal and soybean meal. I guess these
would be the baked beans of our diet.
Other additives can fortify the micro-nutrients of the
finished compost. Examples are rock dust, limestone, seaweed,
rock phosphate, greensand, and wood ashes.
In natural topsoil, only about half the total volume of the
soil is solid. The remainder is air and water. Our compost
should be similar in make-up. Break up or chip very coarse
materials like corn stalks. Particle size should be from
dust-like up to 1/2 inch in size. Keep the compost pile moist
but not saturated. Layer the compost with about 10 percent soil
mixed into each layer.
A good functioning compost will rapidly grow microorganisms
and temperature will rise rapidly. Temperatures may reach
170 degrees F over a few days or weeks. Then the temperature
will drop and level off for days or weeks. Turning the pile
occasionally will ensure the mix optimal for god
decomposition.
Even if conditions are not ideal you will still get
compost. Sometimes it just requires more time.
Making your own compost can be fun and you are contributing
to the process people like to call organic gardening. Go for
it!
