Elements of Permaculture, class two: Design methodologies, reading the landscape, mapping flows of energetic materials, slope, zone, sector, design elements & design functions. Also indoor plumbing, crabs, etc.
Composting: A Tour of Techniques From Manure to ObscureBen Capozzi
Here's my presentation from a November 2014 public lecture on composting. I've had many requests for copies of this!
Invited by the Southside Virginia Master Gardeners Association, I pulled together material from my training as an MG, but also lots more from my certificates in Permaculture and the Soil Food Web. My goals were 1) to share enthusiasm for this eco-friendly practice, 2) take the apprehension out of the process, and 3) encourage systems-level thinking to reduce, re-use, and recycle yard waste. We can keep good biological matter and carbon out of our landfills and use their nutrients to build soil life in our own backyards.
Based on feedback afterwards, I seem to have done a pretty good job.

Composting Troubleshooting Common Issues and SolutionsTriuPhm16
Discover common composting issues and their solutions in this comprehensive guide. Learn how to troubleshoot your composting process and achieve successful results.
Compost is simply decomposed organic material. The organic material can be plant material or animal matter. While composting may seem mysterious or complicated, it’s really a very simple and natural process that continuously occurs in nature, often without any assistance from mankind. If you’ve ever walked in the woods, you’ve experienced compost in its most natural setting. Both living plants and annual plants that die at the end of the season are consumed by animals of all sizes, from larger mammals, birds, and rodents to worms, insects, and microscopic organisms. The result of this natural cycle is compost, a combination of digested and undigested food that is left on the forest floor to create rich, usually soft, sweet-smelling soil. Backyard composting is the intentional and managed decomposition of organic materials for the production of compost, that magical soil enhancer that is fundamental to good gardening. Anyone can effectively manage the composting process.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
School Gardening Guide - Composting in the School Garden ~ Massachusetts
1. Composting in the School Garden
Farmers, gardeners, homeowners and schools all over Massachusetts are recycling food and yard wastes at the
source, reducing the waste flow, protecting the environment and utilizing this valuable soil amendment. Adding
a composting program to your school garden is also a way to teach first hand about soil science, decomposition
and environmental sustainability. This guide provides an introduction to the science, how-to and options for
school composting.
Decomposition is a natural biochemical process in which bacteria, fungi and other microscopic organisms
convert organic wastes into nutrients that can be used by plants and animals.
Composting is a controlled process that manages the natural recycling systems
of decomposition, creating optimal conditions for it to occur. The result is a
dark, crumbly, nutrient-rich, soil-like substance called humus, or compost.
The Benefits of Composting
Compost is a valuable resource that can be used as a supplement to enrich
the soil with nutrients, increase moisture retention, improve soil structure and
provide a good environment for beneficial soil organisms.
Composting also helps protect the environment. The Environmental Protection
Agency estimates that 25 percent of the solid wastes that Americans generate is food scraps and yard wastes that
could be recycled through composting. These useful materials are too often sent to landfills and incinerators or
go down the drain through the garbage disposal.
This trash clogs the landfills taking up limited space. Landfill wastes can cause water pollution and production
of methane gas from anaerobic decomposition. Incineration reduces the volume of wastes, but produces flue
gases that permeate the atmosphere and toxic ash that must be buried.
Use of the garbage disposal for food wastes places unnecessary burdens on the water supply, requiring about
eight gallons of water to dilute a pound of wastes. Wastewater treatment plants then require more chemicals,
produce more sludge, and consume more energy to process the increased volumes of water.
Composting also provides an opportunity to observe nature at work and demonstrate interconnections.
Classroom discussion can center on soil science, waste reduction and management, decomposition, watershed
protection, pollution prevention, bio-diversity, nutrition and more.
Organic Waste Decomposition
Many different soil organisms called decomposers digest the organic wastes. Most are microorganisms, too
small to be seen by the human eye. Other macroorganisms are large enough to easily be seen. Each organism
has a role in the web of the compost pile. Energy flows from organism to organism as one is eaten by the
next. Heat builds up in the pile as a byproduct of the microbial work.
Naturally occurring bacteria start the process. They are the most numerous organisms and do
the majority of the work. It is estimated that a tablespoon of soil contains billions of bacteria.
Fungi and protozoans take over during the next stage of decomposition, when the organic
material has been changed to a more digestible form.
Later in the cycle, earthworms, nematodes, millipedes, slugs, land snails, and springtails do their
part, eating the level one organisms. In turn, other organisms will eat them, primarily centipedes,
mites, beetles, pseudoscorpions, spiders and earwigs. Some organisms, like the earthworm, also
consume organic residue.
2. How Does it Work
Successful composting occurs when the decomposers are provided with the optimum
conditions to flourish. They need food, air, water, space and a habitable temperature.
Food: All organic material contains both carbon and nitrogen in varying amounts.
The microorganisms need carbon for energy and nitrogen to grow and
reproduce. They are most productive when the ratio of carbon to nitrogen is 30:1
“Brown” woody material is high in carbon. It is mixed or layered with damp,
“green” material, such as vegetable scraps and grass clippings, which is high in
nitrogen. A recipe of three parts “brown” material to one part “green” material (by
volume), will result in an overall carbon to nitrogen ratio of 30:1.
Air: Compost micro-organisms are aerobic and need oxygen. The rate of
decomposition is increased by addition of air to the pile.
Moisture: The micro-organisms in the compost pile thrive in damp but not soggy
conditions. Fifty percent moisture is ideal. If material is not damp
enough, the composting process will stop. If leaves rustle, they’re too
dry. If the material is too wet, the air spaces will fill with water resulting
in anaerobic conditions and odor.
Volume and Temperature: Bacteria give off metabolic heat. As populations
increase, more heat is produced and trapped in the center of the pile causing the
temperature to rise. This creates a good environment for other heat-loving organisms
to multiply. The most efficient decomposing bacteria thrive in temperatures between
100-160 degrees F. As temperatures reach 105-170 degrees F, thermophilic bacteria
speed decomposition and heat up the compost even more, killing most weed seeds
and plant pathogens. The pile should be large enough to maintain heat.
Compost is a great resource that will improve the fertility of the soil by holding
nutrients until plants can use them. It also improves the structure of the soil by
loosening and aerating it, while improving the water holding capacity.
Developing your Composting Program
The tested strategies below will help to plan the size and type of program.
* First investigate the need and goals for your composting program.
Autumn leaves are “brown”
compost materials.
Food scraps are “green”
compost materials.
Untreated grass clippings are
“green” compost materials.
Will your compost be primarily for the school garden, for other classroom food scraps and/or other
school meals such as lunch in the cafeteria?
How much waste is produced currently?
Do a waste audit to determine quantity of each type - trash, recyclables and compostables.
Where does it go now?
Could a waste reduction education program reduce some of these materials?
Can alternative compostable or recyclable food service items reduce some trash?
* Meet with the school administration, faculty, cafeteria staff, custodians and interested parents. Gain their
support and build ownership. Form a planning committee and divide the tasks.
* Identify interests and knowledge. Introduce the topics of separation, recycling and composting and the
educational benefit. Survey students and teachers to assess their knowledge, interest and cooperation. Plan a
school wide education strategy. Get students involved in the planning and daily maintenance.
3. Make a plan. Design the waste separation and collection system. How will collection be
best monitored to assure success? Define tasks and time requirements. Address container and
sanitary concerns. What permits and approvals are required?
Determine how the compost, recyclables and trash will be handled. If composting on
site, design compost bins that take into account your size needs. Introduce any accompanying
educational opportunities that support curricula. Plan division of tasks, maintenance and use of
finished compost.
Building the Compost Pile
Select a bin that is appropriate for your setting. There are many commercial containers available; others can be
made from easy-to-find materials. Bin designs include 1, 2 and 3 bin systems made out of wood or bricks, and
barrel turners. Some towns distribute compost bins funded by Massachusetts DEP. In an urban setting, choose a
rodent-proof bin with a floor, tight fitting lid and no openings wider than ½ inch.
A minimum of one cubic yard is recommended (3’ by 3’ by 3’.) Piles wider or taller than 5 feet do not allow
enough air to reach the microorganisms at the center. Piles smaller than one cubic yard will freeze in the winter,
although the organisms will revive in the spring and composting will resume.
Choose a location for your bin. It should be easy to reach in summer and winter. A shady location is
preferable. In the sun, it will tend to dry out quickly, requiring more water.
Prepare the bin by layering “green” and “brown” materials. Sprinkle a few shovelfuls of soil between the
layers, approximately every 12”, to get the microorganism started. Moisten the pile, so the materials feel like a
“wet sponge.”
“Green” materials are nitrogen rich. These wet materials include: fruit and vegetable scraps; coffee; tea bags;
crushed egg shells; bread and grain; green grass clippings; fresh garden cuttings, annual weeds without seeds;
animal manures (horse, cow, rabbit, chicken, goat and gerbil) and seaweed.
“Brown” materials are carbon rich. They include fall leaves; straw; hay; salt marsh hay; shredded paper;
paper towels and plates; coffee filters; used potting soil; sawdust; chipped brush; wood chips; pine needles and
thin layers of wood ash. Chop or shred materials to increase the surface area and speed the process. Gather these
materials from the school yard or obtain from other local sources. Keep a pile of these next to your compost bin
and use these materials to cover “green” materials.
Once the bin is set up, you can begin to add fresh materials regularly. Each time you add kitchen scraps and
other “green” materials, cover them with three times as much “brown”
material to maintain the ideal 30:1 carbon to nitrogen ratio. A compost
mix too high in carbon will take longer to decompose. A compost mix too
high in nitrogen can get sloppy and smelly. If in doubt, it is better to err
on the carbon-rich side, which reduces the likelihood of odors.
Anything that was once alive is organic and will decompose. For public
health and safety reasons, do not compost: meat; bones; fat; grease; oils;
peanut butter; dairy products; foods cooked with butter or sauce; diseased
plants, dog and cat manure. Other things that are not good for a small
compost pile include weeds gone to seed, weeds that spread by roots and
runners, sticks, banana skins, beech, birch and shiny leaves like magnolia
and holly which are slow to decompose.
4. Turn or stir the material in the bin occasionally to introduce more air supply
and speed up the process. Two piles will permit you to add fresh materials to one,
while you turn and finish the compost in the other bin. Turning the pile with a
pitchfork or inserting air tubes such as PVC pipes with air holes drilled into them
into the center increases aeration. An odor like rotten eggs indicates anaerobic
decomposition. A healthy compost pile does not smell!
With frequent turning compost can be ready in about 3 months. Composted
plants and leaves from the fall could be ready for spring soil amendment. Once
the compost stops heating up and the original ingredients have transformed into
dark, rich, crumbly, sweet smelling humus, the compost is finished.
School compost often benefits from sifting before use, to take out anything that is not fully decomposed.
Make a sifter using half inch hardware cloth (wire mesh) stapled onto a wooden frame that will fit over your
wheelbarrow or cart. Shovel compost directly through the screen into your cart and transport to the garden.
There are many ways to use finished compost in the school garden: To use compost as a soil amendment,
shovel compost about four inches deep onto vegetable beds and dig in before planting. You can blend your own
seed starting mix by blending compost, peat moss, packaged soil and perlite, or a potting mix for older plants
with equal parts compost and packaged soil. Make a compost tea to fertilize your plants. Soak a burlap sack full
of compost in a bucket and seep several days until the “tea” is a light brown color, water your plants with this
nutrient-rich solution. Mulch plants, shrubs and trees with an inch or more of compost. Top-dress lawns with a
mixture of finely sifted compost and sand.
Avoid Attracting Pests to your Compost Pile: A well designed and maintained compost system will not attract
unwanted insects and animals. Line the bottom and sides inside your bin with brown materials. Enforce burying
green materials in the center of your pile with a cover of at least several inches of brown
material. Make sure your bin has wire mesh or other rodent - proof design. Line your
compost bin with bricks. Consider attaching mesh to the bottom of your bin to prevent
burrowing. Have a secure lid. Some schools with high animal pressure, may need to
have their compost bin off-site, inside a fortified area such as a courtyard, or to compost
indoors, in worm bins.
If you don’t have enough space to compost outside at your school, you can compost right
in the classroom using a worm bin, with vermicomposting.
Vermicomposting
Vermicomposting is composting with earthworms. Earthworms speed up the composting process, aerate the
organic material, and enhance the finished compost with nutrients and enzymes from their digestive tracts.
Red worms (Eisenia foetida) are best suited for worm composting. Also known as “red wigglers,” these are
the worms typically used for fishing. They are smaller than common garden earthworms and red brown in color.
Originally native to Europe, redworms have naturalized in the U.S., thriving in decomposing organic material
such as leaf piles and compost heaps. They are surface feeders and eat many of the same foods as humans.
Redworms are efficient processors of organic wastes, eating and
expelling an amount equal to their own weight every day. They are also a
good indicator of fertile soil with a high organic content and a lack of toxic
substances. Redworms adapt well to changes in temperature, although they
prefer a range between 40 and 80 degrees Fahrenheit.
5. They are also extremely prolific. Fertilized eggs will develop in a cocoon in about three weeks. Two or more
young may emerge. In three months the worms become sexually mature and will start breeding.
You can purchase worms from a commercial vendor. Many are available on-line, and you may be able to find
a local source in the phone book under “Fishing Bait” You can also collect redworms from decaying leaves,
manure piles or compost piles. A pound of worms is enough to start most bins.
Building the Worm Bin
You can order a special worm bin from a supplier or make your own from wood. The easiest and least
expensive method is to convert a large plastic storage container. Select an opaque container with a lid, as
worms prefer darkness. A deep bin (15 inches or more) is preferable, allowing more room for layering and
burying fresh material. The larger the container, the more material you will be able to compost.
Drill ⅛ inch holes in the sides and cover of the container,
approximately three inches apart, starting four inches from the bottom.
You may also choose to drill holes in the bottom. You will then need
a tray to catch excess moisture. If you don’t provide bottom drainage
holes, add extra dry material if the bins starts to develop puddles.
Next fill the bin with bedding. This is organic material that provides
enough air space for the worms to survive and breed. Bedding can also
be used to cover food scraps. The worms eat the bedding along with kitchen scraps to make the compost. Many
high carbon bedding materials may be used, such as chopped dry leaves, shredded paper, ground cardboard or
peat moss mixed with vermiculite. Bedding can be a combination of materials. Fill the bin about 3/4 full.
Add water to the bedding material until the moisture content is 50 percent (as damp as a wrung out sponge).
It is important to keep the bedding this damp or the worms will die. Mix a few handfuls of soil or finished
compost with the bedding. Site the bin in a location where it will stay between 55-75 degrees F. At lower
temperatures worms will stop reproducing; they will die at higher temperatures.
Add 1-2 pounds of redworms, based on the size of the container. There can be as many as 500-2000 worms in
a pound depending on the size of the worms. Add only small amounts of food scraps until the worm population
increases to handle more (3-4 months). The worms will begin to reproduce after just a few weeks. Also, the
worms can’t eat the food until it starts to decompose; be patient.
Worms will eat any type of kitchen waste including vegetables, fruits, tea bags, coffee grounds and crushed
eggshells. Do not add meat or meat byproducts. Bury the food scraps enough that they are
always covered by bedding. This prevents development of odors and fruit flies. Don’t add more
food scraps than the worms eat in several days. Chop the food scraps for faster decomposition.
Worms do not like to be disturbed. Bury fresh food just once a week. There is no need to turn
the compost in the bin. Air holes in the sides and the tunneling action of the worms provide
enough circulation.
Turning the garbage into castings as long as they have food, space proper temperatures and
moisture. After about two-to-three months, the container will start getting full; much of the
materials in it will look like soil. It’s time to harvest. Move the finished compost to one side of
the bin and add fresh bedding to the vacant side. Put new food wastes into the fresh bedding only. The worms
will move from the finished compost in search of new food. After a few weeks, remove the lid under a bright
light source. The worms will burrow away from it. Scoop out the finished compost a few layers at a time. Add
fresh bedding. Worm compost is more thoroughly digested than most other composts making it desirable.
6. Fruit flies may be found in and around the bin. They are not harmful; but can be a nuisance. The larvae travel
on the skins of fruits, especially bananas. Make a simple, non-toxic trap by placing a banana peel inside a clear
plastic container. Make three or four holes all the way through the cover with a standard toothpick. Place the
plastic container near the worm bin. Within 24 hours, 99% of the fruit flies will be trapped inside the container
and can be released outdoors.
In the Cafeteria & On-Site Composting
Once you’ve determined that a cafeteria composting program is the goal, it is time to get started.
Use the information collected during the waste audit to determine type and size of the program. It will also help
determine the number of collection containers needed in the cafeteria, and compost bins required outside.
Multiple bins are recommended, so new material is added to just one at a time.
Work with the cafeteria and custodial staff to determine type and location of each
of the collection containers - trash, recycling and compost. Make a plan for
managing each collected material, including cleaning and storing containers.
Develop signage for individual bins and to demonstrate sorting of each type of
material. Make a master list of any possible waste that may come into the cafeteria
and the sorting category.
Recruit compost monitors and offer group training. Assign monitors to all lunches
and post the monitor list in the cafeteria as a reminder.
Plan for managing collected materials following the lunch, including the disposal of trash, transferring
recyclables and taking compostables to the bin.
Once compost is ready, complete the cycle through gardening. Harvest finished compost after three or more
months and plant a garden. If your school is too large to implement on-site composting, try developing a plan
for off-site composting.
Composting Activity Ideas
* It‘s estimated that an average American produces 1,600 pounds of trash a year. Ask student to think about
how much garbage they produce over the course of a day, week, year, lifetime. Make a list of all the things
that they threw out yesterday, this past week. How many of these were recyclable or compostable?
* Monitor your wastes. Keep a log of what is composted and when. Record the amount of wastes composted,
the temperature of the pile, moisture content and other observations.
* Ask each student to research one decomposer organism in depth and make a five
minute presentation.
* Investigate the carbon: nitrogen ratio in the pile. Ask students
to calculate the materials that would result in an ideal ratio of 30:1
for your compost.
* A large percentage of the waste stream is made up of “trashed” packaging
materials, from single-serving cans and bottles to the cardboard, plastic, and styrofoam
that wrap merchandise. Ask students to design and present packaging for a product that
will reduce these wastes for one item.
7. * Explain how worms improve the soil. How are they a good solution to our organic waste problem? What
impact do they have on the natural environment?
* Worms offer lessons in life cycles. Find cocoons and young worm populations in the bin. Ask students to
monitor a worm from cocoon to adulthood. What foods do they like to eat? Which are less popular? Study the
anatomy to find the anterior and posterior end, circular and long muscles and setae. How do these help them
move through the soil?
* Make a worm column or worm observation chamber and trace the tunnels the
worms make in the soil.
* Discuss anaerobic and aerobic decomposition. Set up an experiment to watch
food scraps deteriorate in and outside of a worm bin.
* Collect several samples from various stages of compost. Feel, smell, and look at
the “rotting” materials. Use a microscope to examine the materials. What do you see?
What words would you use to describe these materials?
* Can you identify any of the decomposer organisms?
