One of my conscious and earth-friendly Dressage in the Fourth Dimension students, has recently installed a very simple and affordable solar composting system. The design's simplicity has allowed her to create a "do it yourself" system whereby she will be able to solar compost the manure from her four horses for use in her organic vegetable gardens year-round.
Composting is not a new idea. In the natural world, composting is what happens as leaves pile up on the forest floor and begin to decay. Eventually, the rotting leaves are returned to the soil, where living roots can finish the recycling process by reclaiming the nutrients from the decomposed leaves. Composting may be at the root of agriculture as well. Some scientists have speculated that as early peoples dumped food wastes in piles near their camps, the wastes rotted and were terrific habitat for the seeds of any food plants that sprouted there. Perhaps people began to recognize that dump heaps were good places for food crops to grow, and began to put seeds there intentionally.
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. Many states in the USA have stated goals or legislative mandates to drastically reduce the volume of waste being sent to landfills. Utilizing yard and kitchen wastes (which make up about 30% of the waste stream in the USA) is a big part of the plan to minimize waste overall.
