Learning how to make compost is easy and can reduce the amount of organic trash going to the curb every week. Composting will help you reuse some of those kitchen scraps, like that left-over salad, and give you a rich, fertile soil for your garden. All organic matter eventually decomposes. Utilizing this fact, you can easily compost that organic material by providing an ideal environment for bacteria and other decomposing microorganisms to thrive. The final product, humus or compost, looks and feels like fertile garden soil.
