FIELD WORK v.2

Before you start piling on, recognize that there are two types of composting: cold and hot. Cold composting is as simple as collecting yard waste or taking out the organic materials in your trash (such as fruit and vegetable peels, coffee grounds and filters, and eggshells) and then corralling them in a pile or bin. Over the course of a year or so, the material will decompose.
Hot composting is for the more serious gardener but a faster process—you'll get compost in one to three months during warm weather. Four ingredients are required for fast-cooking hot compost: nitrogen, carbon, air, and water. Together, these items feed microorganisms, which speed up the process of decay.
Vermicompost is made via worm composting. When worms eat your food scraps, they release castings, which are rich in nitrogen. You can't use just any old worms for this, however--you need redworms (also called "red wigglers"). Worms for composting can be purchased inexpensively online or at a garden supplier.

To make your own hot-compost heap, wait until you have enough materials to make a pile at least 3 feet deep. You are going to want to combine your wet, green items with your dry, brown items. Start building your organic compost pile, alternating brown and green items. If your compost pile looks too wet and smells, add more brown items. If you see it looks extremely brown and dry, add green items and water to make it slightly moist.

Sprinkle water over the pile regularly so it has the consistency of a damp sponge. Don't add too much water, otherwise the microorganisms in your pile will become waterlogged and drown. If this happens, your pile will rot instead of compost. Monitor the temperature of your pile with a thermometer to be sure the materials are properly decomposing. Or, simply reach into the middle of pile with your hand. Your compost pile should feel warm.

During the growing season, you should provide the pile with oxygen by turning it once a week with a garden fork. The best time to turn the compost is when the center of the pile feels warm or when a thermometer reads between 130 and 150 degrees F. Stirring up the pile will help it cook faster and prevents material from becoming matted down and developing an odor. At this point, the layers have served their purpose of creating equal amounts of green and brown materials throughout the pile, so stir thoroughly.
