Composting
Why Compost? According to the US Environmental Protection
Agency, the amount of garbage generated annually in the United States is
over 200 million tons! Thanks to natural decomposition, food scraps
and yard waste can be recycled at home. But, too much of our
biodegradable, organic garbage just ends up in the trash. Composting is
simple. Returning these organic materials to the soil perpetuates natural
biological cycles and is an ecologically sensible means of using organic
wastes. Composting provides for richer garden soil, improves the texture
and aeration, increases the soil ’s ability to retain water, decreasing
erosion.
How Compost Forms? Composting changes the nutrients in raw
organic material to a form that can be absorbed by the roots of growing
plants. Microorganisms such as soil bacteria and fungi accomplish this
task by secreting enzymes that break down the material. The activity of
these microorganisms can generate temperatures inside the compost pile in
excess of 130 degrees F - hot enough to kill most weed seeds and disease
organisms.
What Can You Compost? Many types of organic materials can be
used for composting. |
How Do You Make A Compost Heap? Place the
heap in a convenient but inconspicuous location. Select a level, well
drained spot, preferably in full sun. Since the compost pile needs to be
kept moist, a convenient water source is helpful. Compost should never get
soggy wet or the decomposition will stop. Compost piles function best when
about as moist as a wrung out sponge and provided with many air passages.
The size of the pile may vary greatly with the amount of material
available, but should be at least three feet wide and three feet high.
Anything smaller will not decompose properly. The top of the pile
should be left flat or with a slight depression in the center to catch
rain or added water.
Compost Bins Available From Douglas County For Just $27.40
Douglas County has purchased a small quantity of compost bins and are
offering them to residents and schools at cost, $27.40. This price
includes an informative booklet titled "Backyard Composting Made Easy."
The bin inludes a lid, holds 12 cubic feet of material, is made of 100%
recycled material, and has a ten year warranty. The lid is made of
recycled milk jugs and battery casings and is manufactured in Drain, OR.
Please call 440-4350 if interested in purchasing one.
What Are The Different Types Of Enclosures? A compost bin is
not necessary but does make it easier to build and maintain a pile. Woven
wire (chicken wire), cement blocks, lumber, snow fence, hay bales, or
bricks can be used to enclose a compost heap. Whatever you use, make sure
there is adequate air movement through the sides. Construction of one
removable wall allows easy access for turning the pile with a shovel or
pitchfork. Some people build adjacent bins, turning the material from one
to the other.
A Crash Course in Composting Composting is like cooking, with
many recipes and variations. Here is the basic approach: All composting
“ingredients” generally fall under one of two categories: “browns” or
“greens.” Browns are dry materials such as wood chips, dried leaves, grass
and other plants. Greens are fresh, moist materials such as grass cuttings
and food scraps (avoid meats, fats and grease).
- Collect as many browns and greens as you can to start your compost
pile. Larger piles tend to hold moisture better and decompose
faster.
- Place approximately equal amounts of browns and greens in a heap or
bin. Always cover food scraps with other composting materials.
- Soak well with water to create uniform dampness (damp as a wrung out
sponge).
- Cover pile with tarp or other material to keep moisture in and
prevent soaking from rain.
For quicker composting (1-3
months):
- Chop materials into smaller pieces and moisten.
- Alternate 3” to 6” layers of greens and browns.
- Mix the pile by turning and stirring.
- Soak the pile once a week.
- For slower composting (3-6 months plus):
- Just keep adding materials to the pile or bin and sprinkle it with
water. It’s that simple!
Troubleshooting:
- Odors? Turn and add brown materials.
- Dry pile? Add water, greens and mix.
- Fruit flies? Stir and add leaves or grass.
There are
two basic methods of composting.
1. Just keep the heap/bin full! The composting recycler may
choose to simply add materials directly onto the pile as they are
generated. For busy folks, this method works fine and compost does happen.
The organic materials will greatly shrink in volume and after six months
to a year the bottom portion of your pile will be rich, crumbly compost.
So keep filling your bin, add water and relax!

How Do You Use Compost? Normally, compost will be ready to
use in 4 to 6 months, depending on the types of organic materials used and
the climatic conditions during the compost period. When the compost is
broken down into a homogeneous mixture; no undercomposted leaves or other
material may be seen; and the pile stops heating, it is ready to use.
Compost can be used as “top dressing” for lawns, for mulching around
landscape and for garden plants or anywhere that additional soil is
needed.
