During much of the year, the landscape provides plenty of raw materials for the compost pile. From grass clippings to leaves, when those supplies are exhausted, many gardeners stop composting all together. But savvy gardeners continue to feed their compost piles using yet another raw material that's never-endingkitchen scraps (figure A). Other than meats, bones and fatty stuff, kitchen scraps are perfect for the compost pile because they contain an extremely diverse mix of materials, and as they breakdown, they infuse the finished compost with major as well as minor nutrients. For example, green leafy scraps are loaded with nitrogen, banana peels are packed with potassium, and eggshells are a great source of calcium. Coffee and coffee filters as well as used tea bags are great for the compost pile, and they help maintain the important ratio between carbon- and nitrogen-based materials.
Kitchen scraps vary enormously in the amount of carbon versus nitrogen that they contain. If you add too much of the nitrogen-based material, namely the green stuff, then you upset that ideal ratio, which can result in a stinky compost bin. To keep odors away, James recommends tossing in equal amounts of carbon-based material, or brown stuff, each time you add the kitchen scraps. Carbon-based materials include items like shredded leaves. James suggests keeping a bucket of them close to the compost bin for easy access.
"For well over 15 years, my wife and I carefully collected every single kitchen scrap that was suitable for composting in a five-gallon plastic bucket we kept under the sink," says James. "Then, once or twice a week, I'd trot up to the compost pile, turn the scraps into it, and rinse the bucket with water." Ultimately, the James family got tired of the whole process.
"The bucket smelled, fruit flies hovered all over the kitchen, and in the middle of winter with temperatures in the teens, it's not like I looked forward to going outside with a bucket full of scraps."
In other words, the whole endeavor was a hassle. So James set out to find a better way of dealing with kitchen scraps. And in the process, he discovered a number of ways to make collecting and composting kitchen scraps a piece of cake. What he found were a variety of different compost buckets made specifically for collecting kitchen scraps.
