Composting is the natural aerobic decomposition of organic matter into a nutrient rich soil amendment. It is composed of “greens”, such as grass clippings or fruit and vegetable scraps, that provide nitrogen, and “browns”, like dead leaves or paper products, that provide carbon. An ideal ratio for good compost is 3 parts brown to 1 part green. This results in a carbon to nitrogen ratio of 25-30:1 for an ideal compost blend.
