| SYMPTOMS | PROBLEM | SOLUTION |
| The compost has a bad odor. | Not enough air/Compaction | Turn it. |
| Too much nitrogen | Add high carbon material such as straw, pine needles, grass clippings or vegetable trimmings and aerate. | |
| Over watering | Add dry leaves or wood chips to soak up water and aerate. | |
| Pile not heating up | Lack of nitrogen | Add a nitrogen source such as fresh manure, grass clippings or blood meal. Mix the pile. |
| Pile needs to be turned | Mix pile by bringing outside material to the center. | |
| Low moisture | When watering make sure the moisture gets to the center of the pile. Try poking deep holes in the pile before watering. | |
| Compost is finished | Finished compost smells earthy rather than rotten or moldy and is dark and crumbly. | |
| The center of the pile is dry. | Not enough water. | Moisten materials while turning the pile. |
| The compost is damp and warm in the middle, but nowhere else. | Too small. | Collect more material and mix the old ingredients into a new pile. |
| The heap is damp and sweet-smelling but still will not heat up. | Lack of nitrogen. | Mix in a nitrogen source like fresh grass clippings, fresh manure, blood-meal or ammonium sulfate. |
| Factors Affecting Rate | Description |
| Oxygenation | Oxygen is required for respiration by all aerobic inhabitants within the pile. Adequate ventilation, wind, convention currents and manual turning or mixing will help keep the anaerobic critters from producing foul odors. |
| Temperature | The optimum temperature for fast decomposition is between 90 and 135 degrees F. Whether it is due to cold climate or insufficient bacterial activity, when the temperature falls below this, decomposition will slow, but not cease. To keep temperatures elevated, try an insulation jacket or better placement for maximizing radiant solar heat. Also choose black colored bins in cooler climate zones. |
| Water Content | An efficient composter needs to have a moisture content around 50% (feels like a damp towel). If it is too dry, decomposition will slow down considerably, while overly wet piles can smell. Keep pile covered during heavy rains, and add rain water when dry spells occur (chlorine in municipal water can kill the organisms in your living system). |
| Surface Area | Maximize this by shredding and chipping all clippings and waste into small pieces. The more area you expose to micro-organisms, the larger the dinner table, and the faster the decomposition. |
| Carbon: Nitrogen Ratio | Organic materials rich in nitrogen are referred to as GREENS (fresh veggie scraps or grass clippings), while the others can be lumped together as BROWNS (hay, twigs, dried leaves). A good general rule of thumb is use 2-3 parts brown to 1 part green. Always remember to layer, layer, layer. If an ammonia smell is detected, ease up on the nitrogen-rich greens. |
Introduction
to Composting Composting is the decomposition of plant remains and other
once-living materials to make an earthy, dark, crumbly substance that is
excellent for adding to houseplants or enriching garden soil. It is the way to
recycle your yard and kitchen wastes, and is a critical step in reducing the
volume of garbage needlessly sent to landfills for disposal. It's easy to learn
how to compost.

The Science and Engineering of Composting
Composting can be pursued at many different levels, from the gardener who likes to produce "black gold" to the operator of a multi-acre commercial composting facility. Gardeners who compost their own landscaping and food scraps can follow a few simple rules of thumb and needn't worry about complex formulas, chemical equations, or studies of microorganisms. These are, however, important considerations for municipal and commercial composting operations because of the need to ensure that the composting proceeds rapidly, doesn't cause odor or pest problems, and achieves temperatures high enough to kill pathogens. Some of the topics in the Science and Engineering section may be far too technical to be relevant to casual composters. On the other hand, some may be intriguing...
Agricultural
Composting: A Feasibility Study for New York Farms - 1993
Supported by the NYS Dept. of Agriculture
& Markets, this study explores equipment and labor costs, land and
management requirements. Agricultural composting is experiencing a resurgence of activity, particularly in the Northeastern U.S. Three fundamental factors are driving this interest: environmental and community constraints on traditional manure management options, increased understanding of the agronomic benefits of compost utilization, and rising disposal costs for materials such as municipal yard waste and food processing wastes which might be managed for a profit in an agricultural setting. Although these factors are encouraging many farmers to re-evaluate composting, there are important tradeoffs to consider as well. Equipment and labor costs, land, and management requirements can be significant, and compost production and utilization techniques are not well established...

Composting
(Journey to Forever): Garden guides often describe composting as "nature's way" of recycling. Not so -- you just don't ever find large amounts of organic matter with the correct carbon-nitrogen ratio, water content and aeration carefully piled up by bears or gorillas working away in the forests with a compost fork and a watering-can, leaving it cooking away at high temperatures and emitting jets of steam. Nature doesn't make compost. Nature mulches.
Worm Composting
Worm composting is a method for recycling food waste into a rich, dark,
earth-smelling soil conditioner. The great advantage of worm composting is that
this can be done indoors and outdoors, thus allowing year round composting. It
also provides apartment dwellers with a means of composting. In a nutshell, worm
compost is made in a container filled with moistened bedding and redworms. Add
your food waste for a period of time, and the worms and micro-organisms will
eventually convert the entire contents into rich compost...
Innovative Uses of Compost - Disease Control for Plants and
Animals: Professional growers are discovering that compost enriched soil can also help suppress diseases and ward off pests. These beneficial uses of compost can help growers save money, reduce their use of pesticides, and conserve natural resources. In the poultry industry, composting has also become a cost-effective method of mortality management. It destroys disease organisms and creates a nutrient-rich product that can be used or sold.

in businesses, schools, and/or government agencies. Many
gardeners compost both yard waste and kitchen waste with compost piles, sheet
composting or some other method during the growing season. Fortunately, very
little yard waste is generated during winter months when cold temperatures make
composting difficult. However, usable kitchen waste is constantly being
generated and must be disposed of. Vermicomposting is the process of using worms
and micro-organisms to turn kitchen waste into a black, earthy-smelling,
nutrient-rich humus. Printable

did this online article about making compost tea.
Compost tea is more or less a liquid version of compost. You take your solid
compost, and soak it in water and let the mixture sit around for a few hours or
a few days. Then you pour the liquid through a screen, or through cheesecloth or
something similar to strain out the solid material into a bucket. What you have
then is compost tea. Compost tea is great, because it is a very mild, organic
liquid fertilizer that provides beneficial live organisms that improve the soil
where you use it. It doesn't burn plants like store bought fertilizers can. See

rough cedar vary from board to board. Redwood is another wood that could be used
and is resistant to decay, or you can find excellent pieces of wood for free
from the scrap pile found outside of most wood supply dealers. This system can
easily handle 2,000 kg. every 6 months which produces around 700 kg of finished

Ohio State University Extension Fact Sheet: Compost returns organic matter to the soil in a usable form. Organic matter in the soil improves plant growth by: stimulating the growth of beneficial microorganisms, loosening heavy clay soils to allow better root penetration; improving the capacity to hold water and nutrients particularly in sandy soils; and adding essential nutrients to any soil. Improving your soil is the first step toward improving plant health. Healthy plants help clean air, conserve soil, and beautify landscapes...

Glossary
of Composting Terms
Composting Dead Poultry - Author: Eldridge R. Collins, Jr., Extension Agricultural Engineer: An acceptable system of disposal for dead birds is essential to any well run poultry farm operation. Moreover, Virginia law requires that poultry producers have an approved means for disposing of dead birds. There are generally two categories of disposal problems: (1) Normal mortality, which is typically about 0.1 percent per day, but fluctuations up to 0.25 percent per day are not uncommon, and (2) Whole flock disposal. Research at the University of Maryland, and field application in other poultry states, have shown that normal mortality can be handled efficiently and safely by composting dead poultry. Composting is a natural process in which beneficial organisms--bacteria and fungi--reduce and transform organic wastes into a useful end product--compost--which can be used as a fertilizer and soil amendment. Although simple in concept and design, dead poultry composters require attention to detail and careful management. Effective July 1, 1992 properly constructed and properly managed dead bird composters are an acceptable method of handling normal flock mortality in Virginia.

Worms for Composting (Vermicomposting)
Vermicomposting is not really a type of composting. In fact, worms are
likely to die if true composting, a heat-producing process, occurs.
Vermicomposting can be seen rather as a form of livestock production. Many
different materials can be used as feedstock for the worms. Animal manures are
quite useable, most without any further preparation. Hog slurries, however, must
be separated, and only the solids are fed to the worms. Poultry manures may
contain excess ammonia and inorganic salts and so they must be processed to
remove these substances which would be toxic to the worms. Plant residues, such
as potato and brewery wastes, have also been tested as feedstocks for commercial
systems.

Worm Composting
Worm compost is made in a container filled with moistened bedding and redworms. Add food waste and with assistance from micro-organisms, the worms will convert bedding and food waste into compost. Worm composting can be done year-round, indoors in schools, offices and homes. It is a natural method for recycling nutrients in food waste without odor. The resulting compost is a good soil conditioner for house plants, gardens and patio containers.
Composting Guide
If you can do only one thing to improve your garden this
year, build a compost pile. No matter your soil type, your climatic zone, or
your choice of crops, composting will enhance your garden soil, resulting in
stronger plants and healthier produce. Organic gardeners have long regarded
compost as the cornerstone of garden soil fertility. Compost builds healthy,
strong plants that are more resistant to pests and diseases. Making your own
compost completes a natural cycle in your garden...

Raising
Earthworms Successfully [PDF] Earthworm growers can make money by selling earthworms and vermicompost or from tipping fees (charging to have organic materials normally disposed of in landfills "tipped" by a dump truck onto the worm grower’s site, to be fed to the earthworms). Vermicomposting is the process of turning organic debris into worm castings (manure). The focus is on processing the waste rather than creating ideal conditions for raising earthworms. Earthworm size and their reproductive rates are frequently lower than those of the same species raised in vermiculture systems. Large vermicomposting facilities typically make money primarily from tipping fees, followed by sales of castings, and then, in a distant third place, by sales of earthworms...
Worm Away Your Cafeteria Food Scraps!
Included for school projects or for those who need a hint on where to get cheap
(free) food for their own beds. Every day, schools and businesses throw leftover food and table scraps into the garbage. The garbage must be picked up and transported to a disposal facility-at significant financial and
environmental cost. Through a process called vermicomposting, food scraps are fed to worms and transformed into a nutrient-rich compost for plants and gardens. Vermicomposting can help businesses and schools save money. By diverting food scraps from a dumpster to worm bins, it might be possible to switch to a smaller dumpster and thus reduce solid waste disposal fees. Through a school cafeteria vermicomposting program, students can learn a valuable, hands-on recyc1ing lesson: food doesn't have to be thrown away. Worm castings can be used to help plants grow in their school or home gardens and grounds. Although this publication focuses on setting up vermicomposting programs in schools, the same guidelines can be used by companies and other institutions that generate food scraps. The Seattle Kingdome and the National Institute of Environmental Health Sciences are two vermicomposting success stories discussed here...
