Beginners Guide to Home Composting

Composting your kitchen and garden waste is a great way to reduce the amount of waste you dispose of in your rubbish bin.  By composting your waste you can generate a free source of rich compost to help improve your garden, and also help to reduce global warming in the process.

How does home composting help to reduce global warming?

When sent to landfill organic waste is compressed under tonnes and tonnes of other waste types.  The organic waste therefore does not have enough access to air, which restricts the waste from being able to decompose properly.  Instead of decomposing, methane gas is produced which contributes to global warming.

The Compost Bin

The first step to start composting at home is to get a compost bin.  You can either purchase a compost bin or you can make your own.  Compost bins can be bought from the majority of garden centres.  The government funded Recycle Now Home Composting Campaign also sells discounted compost bins.

The next important step is to decide where to position the compost bin, which can affect the overall quality of the compost that is produced.  For best results place the bin in a well drained area which has good access to sunlight.  The drainage will enable excess water to drain out of the compost and placing the bin in a sunny spot helps to speed up the composting process.

What waste items can I put in my compost bin?

There are lots of everyday waste items from your garden and kitchen that can go into your compost bin.  These are broken down into ?Greens? and ?Browns?.  Greens are the type of items that provide moisture and nitrogen and are quick to rot.  Items classed as Greens includes:

Grass cuttings 

Vegetable peelings 

Leaves

Fruit 

Tea bags 

Weeds 

Browns are waste items that take longer to rot but provide pockets of air, along with fibre and carbon.  This includes items such as:

Cardboard boxes 

Newspapers (scrunched up) 

Toilet roll tubes 

Egg shells (crushed) 

Shredded paper 

Twigs and hedge clippings

How do I make a good quality compost? 

To make a good quality compost it is important to use a good mix of both 'green' and 'brown' wastes.  It is simply a case of monitoring the compost and adding more waste depending on the look of the compost.  For example, if it looks too dry add more ?green? waste, and if it looks too wet add more ?brown? waste.  Every so often it is also a good idea to mix or turn the contents of your compost bin to add air.

How long will it take for my compost to be ready to use?

This will vary depending on the mixture of waste that is placed into the compost bin, the surrounding conditions and the weather.  In general it should take between 6 and 9 months for your finished compost to be ready to use.

7 Factors Needed for a Compost Pile

Compost, made from decomposed grass clippings, leaves, twigs, and branches, becomes a dark, crumbly mixture of  organic matter. 

Learn how composting works. Even a newbie to composting can make good quality compost. It can be compared to cooking as art or part science. The following 7 factors will help you master the art of composting.

1. Materials

After a time anything that was once alive will naturally decompose. But, not all organic items should be composted for the home. To prepare compost, organic material, microorganisms, air, water, and a small amount of nitrogen are needed.

These items are safe to compost at home:

* grass clippings

* trimmings from hedges

* vegetable scraps

* leaves

* potting soil that has grown old

* twigs

* coffee filters with coffee grounds

* tea bags

* weeds that have not went to seed

* plant stalks

These items are Not safe to compost at home:

* weeds that have went to seed

* dead animals

* pet feces

* bread and grains

* meat

* grease

* cooking oil

* oily foods

*diseased plants

2. What To Do To Make It Work

There are small forms of plant and animal life which break down the organic material. This life is called microorganisms. From a minute amount of garden soil or manure comes plenty of microorganisms.

Nitrogen, air, and water will provide a favorable environment for the microorganisms to make the compost. Air circulation  and water will keep the microorganisms healthy and working. The nitrogen feeds the tiny organisms. You may have to add a small amount of nitrogen to the pile.

Putting on too much nitrogen can kill microbes and too much water causes insufficient air in the pile. You just cannot add too much air. 

3. Beneficial Microorganisms

Bacteria are the most effective compost makers in your compost pile. They are the first to break down plant tissue. Then comes the fungi and protozoans to help with the process. The arthropodes, like centipedes, beetles, millipedes and worms, bring in the finishing touches to complete the composting.

4. Smaller is Better

The materials will break down faster if the microorganisms have more surface area to eat. Chopping your garden materials with a chipper, shredder, or lawnmower will help them decompose faster.

5. Size of The Pile 

The activity of millions of microorganisms generates heat in the compost pile but a minimum size 3-foot by 3-foot by 3-foot  is needed for a hot, fast composting pile. Piles that are any larger may hamper the air supply needed in the pile for the microorganisms.

6. Moisture and Aeration

If you can imagine a wet squeezed out sponge with its many air pockets, then this would be the ideal enviroment for the microorganisms in the pile to function at their best. Pay attention while your pile is composting, to the amount of rain or a drought you may have. Water in a drought and maybe turn the pile in a lot of rainy days. The extremes of these two may upset the balance of the pile. The use of a pitchfork would come in handy at this time.

7. Temperature and Time

Keep your pile between 110F and 160F and the beneficial bacteria will love it. Not too cool nor too hot.

The temperature will rise over several days if you keep a good ratio of carbon and nitrogen, maintain lots of surface area within a large volume of material, and maintain adequate moisture and aeration.

-Importance of Compost-

+Compost has nutrients, but it is not a complete fertilizer. 

+Compost provides nutrients in the soil until plants need to use them.

+ It loosens and aerates clay soils

+ Retains water in sandy soils.

-Using the Compost-

+ A soil amendment, mix 2 to 5 inches of compost into gardens each year before planting.

+ A potting mixture, add one part compost to two parts potting soil.

+ Make your own potting mixture by using equal parts of compost and sand or perlite.

+ A mulch, prodcast 2 to 4 inches of compost around annual flowers and vegetables, and up to 5 inches around your trees and shrubs.

+ A top dressing, mix finely sifted compost with sand and sprinkle evenly over lawns.

The final thing I would suggest once you have mastered the art of composting is to look very seriously at making your very own aerated compost tea. This elixir will give you results that are hard to believe.
