Organic composting is a sustainable practice that transforms garden and household waste into a nutrient-rich soil amendment, fostering plant health and reducing the need for chemical fertilizers. This eco-friendly method not only diminishes pollution but also significantly cuts down on landfill waste. In Manchester, for instance, the local council has introduced brown bins for residents to dispose of compostable materials, which are collected biweekly after they have decomposed to less than half their original volume.
Composting is often hailed as nature's own recycling method. It's a process that relies on the natural breakdown of organic matter, facilitated by a diverse community of microorganisms. Unlike the common misconception of a foul-smelling, fly-infested pile, proper composting is odor-free and hygienic. It's a sophisticated form of applied microbiology, where countless species of microbes work together within a complex ecosystem to decompose organic waste.
Organic gardening revolves around the principle of nurturing the soil rather than directly feeding plants. Healthy soil, enriched with compost, naturally supports plant growth. Composting is the cornerstone of soil maintenance, providing a simple yet effective approach to fostering a vibrant garden ecosystem.
Almost any organic material is compostable, but some items should be avoided to maintain a healthy composting process. Quick-rotting substances like grass clippings and young weeds serve as excellent activators, kickstarting the decomposition. However, without a mix of slower-decomposing materials, they can turn into an unpleasant sludge. Tougher plant matter adds structure to the compost and should form the bulk of the heap. Woody debris decomposes at a snail's pace and is best shredded before being added.
While a container isn't strictly necessary, it can help manage the composting process. Compost bins are an affordable option, available in wood or recycled plastic, and can be paired with a wormery or shredder to increase efficiency. It's important to avoid composting dairy, meat, and bread, as these can attract pests.
Finished compost will transform from recognizable plant matter into a dark, soil-like material. For outdoor gardening, a few lingering bits are acceptable, as they will continue to decompose. However, for houseplants or seed starting, it's best to use compost that is fully decomposed to protect delicate roots from microbial attack.
Composting can significantly reduce household waste, with compostable materials often accounting for 20-30% of total waste. By diverting this from landfills, we can lower methane emissions—a potent greenhouse gas—and prevent potential groundwater pollution. Composting not only saves money on waste disposal but also contributes to a healthier, more fertile garden, allowing for the growth of organic fruits and vegetables.
In conclusion, organic composting is a vital practice for any eco-conscious gardener. It's a cost-effective way to enhance soil health, support plant growth, and contribute to environmental sustainability. By understanding what to compost and how to manage the process, gardeners can turn waste into a valuable resource, closing the loop in nature's recycling system.
For more detailed guidance on composting, the United States Environmental Protection Agency provides comprehensive resources. Additionally, the Royal Horticultural Society offers expert advice on creating and using compost in the garden.
Can GM crops feed and save the world?
GM crops and the great debate has been around for 10 years and are people any closer to working out whether they are good for us, the planet or whether they are a necessary evil to feed the world?

Green Energy versus Nuclear Power
I have just been reading about Namibia and how Uranium production is booming and creating jobs in this developing African nation and I thought it was about time I revisited the nuclear power debate after a 3 year break.
