 Composting
involves mixing yard and household organic waste in a pile or bin and providing
conditions that encourage decomposition. The decomposition process is fueled by
millions of microscopic organisms (bacteria, fungi) that take up residence
inside your compost pile, continuously devouring and recycling it to produce a
rich organic fertilizer. 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. Using quality compost improves the soil structure, fertility and general soil health. Healthy soil is essential for healthy plants and vegetables. Compost can increase the water holding and nutrient capacity of soil, which means that less water and fertilizer is required for ongoing maintenance. This can significantly reduce the requirement to use other soil additives and makes compost a very cost effective option for garden maintenance. Composting 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. Finished, mature compost mulch and “compost tea” can be used to control weeds, further reducing the requirement for gardening inputs, such as weed killer and hard work. It's easy to learn how to compost. Today, the use of composting to turn organic wastes into a valuable resource is expanding rapidly in the United States and in other countries, as landfill space becomes scarce and expensive, and as people become more aware of the impacts they have on the environment. In ten years, composting will probably be as commonplace as recycling aluminum cans is today, both in the backyard and on an industrial scale. Compost Bins- There are a tremendous number of options for containing your compost. Some people choose to go binless, simply building a compost pile in a convenient spot on the ground. Others build bins from materials such as recycled pallets, or two-by-fours and plywood. And, of course, there are many commercial bins on the market. A one bin system is the simplest way to make a compost pile, and is a great way to get started. If you plan to make a lot of compost, one bin may not be enough capacity, but adding another can be a simple matter. The basic idea of a one bin system is to make an enclosure for your bin that is at least three feet (or about one meter) across, although you may also choose to use no bin at all if you don't need to keep everything tidy. Possible construction materials include free wooden pallets from local businesses, lumber, cinder blocks, or even steel posts and wire fencing. Once you've made your bin (or decided not to), you might build a pile all at once if you have the ingredients, but it's more likely you'll build the pile over time as you generate compostable materials. Compost Materials- Now that you're ready to start making compost, you need to know what organic materials can and cannot be used in the compost bin or pile. Getting the right mixture of brown (carbon) materials, to green (nitrogeneous) materials will make a huge difference. Adding too much brown material will result in a compost pile that takes a long time to break down. Adding too much green material will result in a compost pile that is slimy and smelly that doesn't break down well. In order for your compost pile to break down quickly and efficiently you should feed it just the right balance of brown and green materials. Improving the Compost Pile- Many of the bacteria that break down your compost need air to survive. A week or two after the pile is made these bacteria will start to die off as they start to use up the available air in the pile. This drop in the amount of bacteria will result in the compost pile cooling off a bit from it's peak temperature. When this happens it's time to turn the pile to get more air into it. The key to getting the correct moisture in your compost is to moisten the pile without making it too wet and soggy. Many people recommend adding moisture until the material is as moist as a wrung out sponge. This is far too wet. If you can squeeze water out of it, it's definitely too wet. If your pile is too wet adding some dry brown materials such as chopped leaves or hay should help dry it out. Shredding increases the surface area that the compost microbes have to work on and provides a more even distribution of air and moisture among the materials. Since it's the brown materials that take the longest amount of time to break down, shredding them significantly reduces the finishing time of compost. |
