I have always been interested in composting. As a child I loved the look, and feel of soil in the field after my dad had turned over the corn stubble, and it had time to decompose. At the time I did not know how it worked, but the smell of that soil will be with me forever. It was like smelling something new. Like a new car smell only a hundred times better. What I didn't know was that it was something new, recycled, rejuvinated, composted. I was smelling... earth!
Compost, when done right has that smell. My latest compost bin is the largest I have ever built. I gave much thought to what type of bin to use, and decided on a 4' x 4' box type. There are many different bins you can purchase. Some can be rolled or tumbled to mix material inside, while others are boxes made of plastic that can be stacked. Another method is to use wire fencing to make a round bin. Even easier than that is to just build a pile. My bin uses 2 x 4's, wire fencing, old shutters for a door, and old bricks for the floor. All salvaged materials, which fits in with my commitment to recycle.
To make good compost, you need three basic materials, browns, greens, and water. Brown materials will be the bulk of your pile. This could be leaves, straw, old hay, shredded tree trimmings or sawdust. Green materials would be grass clippings, kitchen scraps, coffee grounds, crushed egg shells, and yard waste free of weed seeds. Layer your materials begining with a layer of rough material like tree trimmings on the bottom. Next alternate layers of browns and greens, wetting each layer as you build your pile. Don't over water, you want your material damp not soggy. Add a shovel full of garden soil or finished compost in between layers to start the whole process. Microorganisms in the soil are what will consume the materials turning them into compost. As decomposition progresses, heat generated by these microorganisms will raise the temperature in your pile. A well fed pile will generate temperatures of 140 to 160 degrees. It is possible to reduce weed seeds and disease at these temperatures making compost seem like gold to gardeners. Monitor your pile for moisture and turn periodically to aerate. By turning, you add oxygen and introduce less decomposed material on the outside to the center of the pile. Depending on how well you manage your compost pile, you could have finished compost in three months to two years.
All of this is just my way of making compost. This is a very simple explanation, I could go into much more detail. There are volumes of information on the internet and many books on this subject. Choose a method of composting that you think will work for you and experiment. If you normally bag grass clippings and place them in the trash, save them and put them in your compost bin instead along with your kitchen scraps. Things to avoid are meats, grease, dairy products, and pet feces. So get outside and have some fun, get some excercise, and make some microorganisms happy.
