Microscopic decomposers need nitrogen to help them break down the carbon. Nitrogen comes into the pile in the form of green plant tissue. This can be freshly cut grass clippings, hedge clippings, vegetable kitchen scraps, coffee grounds, tea bags, juice pulp, spent annual plants, or finished manure from vegetarian animals (that’s chickens and cows rather than cats and dogs). As bacteria use nitrogen to break down carbon, they release heat. Heat is a good thing because it speeds up decomposition.
Dry material resists decomposition, and earthworms, fungi and bacteria need moisture to live. To make compost, the pile needs to stay damp. Sprinkling water as you add each layer of ingredients to your bin is a good way to make sure your pile starts off with the right moisture level.
On the other hand, swampy conditions can drive air out of the pile. Some of the most helpful composting bacteria (psychophiles, mesophiles and thermophiles) need oxygen to work. If the pile is too wet, or if it isn’t vented or turned regularly, they may run out of enough oxygen to stay alive and keep eating. Add air by turning your homemade compost with a pitchfork or poking holes deep into the pile with a pole or stick.
By adding the four essential ingredients, you’ll provide the sort of environment that supports the decomposers that make compost. But how do the decomposers find their way into the bin? Some people have the “If you build it, they will come” philosophy when it comes to introducing composting organisms. Others purchase bacterial and fungal spores to inoculate their bins. An easy, effective way to introduce the critters that make compost happen is to sprinkle some finished compost or garden soil into a new pile of fresh ingredients.
