Almost any thing that once lived can be broken down into compost in a well managed pile. Added to your garden it creates soil with a high humus content and rich in plant nutrients. A list of the benefits of compost make it sound like a miracle product. Compost acts like a sponge in the soil, holding comparatively large amounts of water that is released slowly as the soil dries. It keeps the soil loose and fluffy.
Compost provides food for microorganisms in the soil.
These bacteria and other life forms produce acids that dissolve nutrients from soil solids and put them into solution for use by plant roots. Composting kills weed seeds. Such a valuable material should be hard to produce, but it it is not. Like many things it's more efficient to make in large quantities rather than small ones. Two things regulate the rate at which your organic material material becomes compost, heat and moisture.
