Composting - Debunking the Bad Rap |
|
Composting is a never ending process -- WRONG |
Doesn't composting take forever? No, depending on
the conditions & materials it may take as little as 3 months. Look for the signs of a
"finished" compost. When the compost is ready to put in the garden, it will be dark,
crumbly, and will have that wonderful earthy smell. It will have reduced to about
one-third of its original size.
Don't be tempted to use your compost before it is
finished! Your plants in the amended area can develop problems related to nitrogen
deficiency or phytotoxicity.
To use compost as an amendment, start by turning the
garden soil to be amended, then apply compost over the area at the rate of 1" — 3" and
turn it in to a 6" — 8" depth.

In order to get started composting, you need to spend lots of
money. -- WRONG |
Although many commercial bins and tumblers are available,
you don't really need them. Many gardeners successfully produce rich compost by just
piling refuse in the corner of their property. The pile isn't the most beautiful
thing in the yard, but it does make compost. Your compost pile should be too small
(minimum pile size is three feet on all sides or 27 cubic feet) and not too large either
(maximum size is 5f feet on all sides or 125 cubic feet).

You need a big yard to make a compost -- WRONG |
Even a small yard produces a organic materials that can
be used in a compost. You can add yard wastes such as grass, leaves, weeds,
brush and small twigs. These materials make up the lions share of your
compost. You can even add shredded black & white newspaper to the compost.
You read the paper don't you?

Compost pile stink to high heaven, don't they? -- WRONG |
Actually, no. If the compost pile is emitting an
unpleasant odor, then the pile has not been proper maintained. Odor is a sign that
something is unbalanced -- too wet, too much "green" material or too little oxygen are the
most common reasons. The pile should not be soaked, just damp. It needs
to be "stirred" every couple of days so that contents stay "fluffy" and not compacted.
If you smell a strong ammonia odor, then you have added too much grass. Counter this
by adding more dry material that has a high carbon makeup.
If your compost starts to smell bad chances are it's too
wet. Excess water fills the voids between the materials, impeding diffusion of oxygen
through the compost and leading to anaerobic conditions
Mixing in additional bulking agent such as dry wood chips,
cardboard pieces, or newspaper strips is likely to alleviate the problem.

I hear that you can not compost rhubarb leaves. -- WRONG |
Even though the leaves are poisonous if eaten, they can
safely be place in the bin. The toxins are broken down during the decaying process.
By the time the compost is ready, there will be no trace of the toxins. So shred and
compost to your heart's content.

A good compost is created by following a strict recipe. --
WRONG |
While you certainly need certain "ingredients" to produce
a successful compost, you don't need to fret over the proportions. The compost needs
carbon, nitrogen & oxygen to work. Carbon comes from material like fall leaves and
nitrogen comes from grass clippings, garden refuse and food scraps. Oxygen
comes from aeration when the pile is turned on a regular basis. Composting is a
natural process - organic matter rots and breaks down into rich compost. Making
compost is more art than science.
Mixing certain types of materials or changing the
proportions can make a difference in the rate of decomposition. Achieving the best mix is
more an art gained through experience than an exact science. The ideal ratio approaches 25
parts browns to 1 part greens. Judge the amounts roughly equal by weight. Too much carbon
will cause the pile to break down too slowly, while too much nitrogen can cause odor. The
carbon provides energy for the microbes, and the nitrogen provides protein.

|
Composting takes a lot of my time & attention. -- WRONG |
Well, again no. My favorite Master Gardner, Paul
James (seen on HGTV) doesn't do anything to his compost piles. He just leaves them
alone for several months. I prefer to turn the pile on a regular basis.
Apparently either method works. Turning the pile does speed up the process.

|
Wild critters are attracted to compost piles. -- WRONG |
Wild critters, like field mice or raccoons are attracted
to meat products or your pets manure. If kitchen wastes are not covered or turned
under, they could cause a pest problem. You can discourage their visitations by not
putting these protein items in your compost.
|
|
Compost is just soil, right? -- WRONG |
No, soil is dirt. Soil is a mixture of minerals,
natural chemicals and organic materials. Some of the organic material found in your
garden-variety soil are plant material, insects, worms, fungi and bacteria.
Compost, on the other hand, is all organic. It is composed of is made up of organic
matter, microbes and nutrients. Compost is used to condition and fertilize flowerbeds and
vegetable gardens; it enriches the soil by slowly releasing nutrients, improving moisture
retention, smothering weed seeds and slowing erosion. And as Martha Stewart says,
"That's a good thing."

|
Compost is really peat moss, right? --
WRONG |
Again,
a common misconception. Peat is harvested from, well, peat bogs. They are
formed when plant material have decomposed over a long period of time. Although peat is
plentiful right now it is considered a limited resource. Mother Nature makes peat.
|
|
Layering the compost is the only way to make it. -- WRONG |
Layering is traditional, but mixing the materials works
as well.
|
|
Chemicals are needed to make the compost work. -- WRONG |
It is true that the addition of commercially available
compost activators that will speed up the process,
but they are not necessary. These commercial products contain dormant fungi and
bacteria that become active in the compost and begin breaking down debris.
Remember that these same fungi are already in the garden, present in soil and in finished
compost. So tossing in compost or good garden soil will also do the trick.
I have even found that some gardeners add a can of beer every couple of months.
The yeast in the beer is good for the bacteria and such in the compost pile.
