What Is Compost?
Compost is
composed of organic material ranging from leaves and
wood chips to household refuse which, when broken down,
becomes one of nature's best garden fertilizers and
richest mediums for potted plants. It is made up of
waste material that is generally high in either carbon
or nitrogen.
Why Compost?
Below are just a few of the excellent reasons why so many gardeners and
horticulturists are taking advantage of this time-tested
practice:
 |
Easy, convenient way
to dispose of garden refuse (often prohibited from
city dumps)
|
 |
Ideal for growing
organic herbs, fruits and vegetables
|
 |
Conserves dwindling
landfill space
|
 |
Saves money on
fertilizer and other store-bought gardening products
|
 |
A good alternative
to chemical fertilizer for parents, pet-owners, and
others concerned with the environment and their health
|
 |
Helps ward off pests
and weeds without chemical pesticides or herbicides
|
 |
Improves plant
growth and quality
|
 |
Reduces erosion and
run-off
|
 |
Restores nutrients
back into the soil
|
 |
Helps loosen soil
and can be used as mulch
|
 |
Breaks down clay
based soils
|
For the first time,
the new Urban Compost Tumbler (UCT) is making composting
practical and easy for gardeners in just about any urban
or suburban setting.
What makes High Quality Compost?
High quality compost is compost that is completely
"done" and ready to use. It should resemble soil and
have a pleasant, earthy aroma. Lower quality compost is
more sludge-like and bears a foul odor. It is usually
made of materials that have not fully broken down.
Composting 'Recipe'
You can use almost any recipe or formula for
composting in the Urban Compost Tumbler you like.
However, following some basic rules will help. You need
Carbon (brown stuff), Nitrogen (green stuff), Oxygen,
Moisture, and Time in the mix. The degree of
attention you give to the materials you use, the quality
of those materials, their ratios in the mix, particle
size and moisture control will all influence the speed
of composting and its quality.
What to Compost
With only a few exceptions, if it is a plant and
grows out of the ground or in the water, you can compost
it. All organic material contains carbon and nitrogen to
greater or lesser degrees. Materials high in carbon
generally are brown in color (autumn leaves, straw, dry
grass, etc.) and materials high in nitrogen are
frequently green in color (fresh cut green grass,
kitchen scraps, etc.).
A good rule of
thumb is to have roughly equal amounts of "brown" and
"green" material, by weight. This is known as the 50/50
rule and will tend to balance the carbon to nitrogen
ratio to the appropriate level. Since measuring and
weighing all your material can be tedious, the 50/50 by
weight rule is simpler and usually accurate enough.
Compost must be
turned more frequently to get oxygen back into the mix
when using higher nitrogen ratios. A real advantage of
the Urban Compost Tumbler is you no longer need to be
quit e as concerned with this ratio, the patented aeration system takes care of that.
Odor and pests are
not a problem as the Urban Compost Tumbler is an
enclosed unit and turning the tumbler daily requires
very little effort as opposed to turning a compost
pile. Excess moisture can cause odor problems, the while composting, the compost
should be about as damp as a wrung out
sponge.
Another rule of
thumb to remember when mixing material for composting is,
the more varied the materials, the richer the compost.
When practical, try using a variety of "greens" and
"browns" in the mix. Below is a general guideline of
example materials to use and not use in composting. This
will vary based on materials available and the
individual's experience in composting.

Composting Using the Urban
Compost Tumbler
Collect and Prepare the Material:
 |
Gather together enough
"brown" and "green" material to fill your Urban Compost Tumbler
all at once.
|
 |
Using the 50/50 rule, by
weight, use approximately half-green and half-brown
material. For ideal composting results, prepare the
material so the particles are approximately 1/2" to 2"
inches or less in size.
|
 |
Use a chipper for larger
items or your lawnmower for smaller items.
|
Fill the Urban Compost Tumbler:
 |
Leaving a little
compost (seasoning) in the barrel from the time
before. Begin putting in equal amounts of "brown"
and "green" material.
|
 |
Every 5" to 8" you
may want to add a handful of a natural compost
starter, alfalfa pellets, or manure, and then
dampen if needed.
|
 |
The mix should be
as damp as a wrung out sponge. It should feel
wet but you should not be able to squeeze out
water.
|
 |
It is
important to avoid packing the material down
too much, as it will impede mixing when the
unit is tumbled.
|
 |
Leave a little
empty room in the barrel to allow mixing.
Also remember that a full barrel will turn
easier than when half full.
|
Let Nature Do the Rest:
 |
Screw on the
lid (be sure the aeration holes are (open/clear) and
let it sit.
|
 |
Weekly,
rotate the tumbler 2 or 3 times in each
direction - daily rotation is even better.
|
 |
Oxygen is the
key to rapid composting.
|
 |
Especially
during the first week or so, check to be
sure that the material was not packed so
tight that it is not mixing when tumbled.
|
That's It! You will have beautiful compost
in as little as two weeks!
