While browsing through the kitchen one day, I picked up my compost bucket to move it. It was crawling with tiny red ants (we call them piss ants, don’t know what you call them).
I exclaimed to my friend who was standing nearby, “Damn! There’s ants in the compost!”
To which Joe replied, “Yeah, I hate when ants get in my rotting stuff.”
Composting is an important way to introduce or replace essential elements into the soil. Elements such as carbon, nitrogen, magnesium, sulfur, calcium, phosphorus, potash, and trace minerals are all necessary to maintain living soil that will produce nutrients in the food you are growing. The health of the soil will be a determining factor in pest and disease resistance as well.
Nature composts in the forms of manure, earthworm castings, and decomposing plant and animal bodies. These things improve the structure of the soil, giving it good aeration and water retention. This means the soil will be easier to work. I don’t know about you, but that’s quite important to me. Of course, you can buy compost, but making your own will save you money, and you’ll have some control over what goes into your soil. If you’re buying organic groceries, or growing organic foods, then when you put some peelings on your compost pile, you’ll know you aren’t composting pesticides or herbicides.
There are many ways to create your own compost. This is one of them that incorporates the necessary elements. You want to find what works for you and still gets the job done. You’ll probably want to keep the compost pile close enough to your kitchen that you don’t begrudge the trip to go plop it down on the pile. You’ll not want it close enough to your house that an otherwise helpful insect becomes a pest indoors. Don’t let bugs worry you, though. They have their place in the breakdown of things.
So, first some basic things you want in your compost, and then we’re going to lay out how you build the pile, as well as what to put in it and what to withhold. You want the pile to contain microbes, organic matter, manure, and soil. The compost pile also needs moisture and air.
Organic matter includes plant and animal life, like leaves, grass, wood, garbage (careful with this), natural fiber clothes, hair, and bones.
Microorganisms which decompose or digest organic matter come along with this organic matter, with different microbial activity present on different plants, animals or what have you. Be sure to add at least three different kinds of crops to your compost pile for microbe diversity. The decomposition of the materials creates heat in the pile.
Soil is added because it also contains microorganisms that break down compounds, fix nitrogen from air, or tie up nitrogen surpluses.
It is a good idea to loosen the soil beneath the pile to help with drainage. You want your first layer on the ground to be bulky. I use refuse from cane plants, sunflower stalks, corn stalks, twigs, and small branches. The spaces between these stalks help air flow in the pile. Fungi will play a role in the breakdown, but you want aerobic breakdown going on in there also.
The next layer should be dry vegetation, followed by green vegetation and kitchen wastes, then manure, and finally soil. Always cover your kitchen wastes with soil, to discourage massing of flies or what have you. You need not worry if you have no manure, some recipes call for only dry vegetation, green vegetation and soil. Layers should be, ideally, 1 to 2 inches thick, but you can add things at random. The randomly built pile may take longer to decompose.
So, you continue layering in this manner, minus the “bulk” layer. (After the first bulk layer, you can add little twigs and things without building a layer.) You should moisten the layers as they go into the pile. You don’t want it soggy, so water lightly. Too little water and you’ll have decreased activity, too much and you’ll drown the aerobic microbial life. If your compost pile gets heavy rain and waterlogged, you will have to decide if you want to cover it during downpours or spread or turn the pile to air it out somewhat. After your compost sits for about 3 weeks, turn the pile, checking to make sure it is moist throughout.
Site your compost pile in the shade, with or without a container. For airflow through your compost, you probably aren’t going to want a closed container. A simple, inexpensive container can be made from chicken wire, for instance. Under a deciduous oak tree is an ideal location, or under another deciduous tree. Any shady place may be used, but keep your compost pile 6 feet from tree trunks, to avoid harboring insects that could be damaging to the tree.
You can speed decomposition by adding nitrogen (manure), increasing aeration by periodic turning of the pile, or breaking larger pieces of whatever the material into smaller pieces. Biological activity is highest in spring or autumn. I just compost year round and let it “cook” longer if some of it doesn’t decompose. A biointensive pile such as this should be ready to use in 3 to 6 months.
Here’s some great stuff to add to your compost pile: tea bags, coffee grinds, raw peels from fruits and vegetables, grass clippings, leaves, egg shells, plants pulled from your garden after their season,
Here’s some stuff you keep out: meat products (raw or cooked), grease, cooking oil. Put your raw peels and eggshells in there, but cooked food is not recommended. As far as paper goes, you’ll have to make that call for yourself but consider carefully. Do you know what’s in it? For instance, is your newspaper printed with toxic inks? Some papers are printed with soy-based ink. White coffee filters have been bleached and linked to some health risks. Brown, less “processed” filters are available, and are safer for your body and your soil. I would consider avoiding office papers, junk mail, and old receipts as well. Doesn’t the very smell of them indicate serious chemicals to you? Does to me!
What about adding weeds? Your compost may or may not be hot enough to render some weed seeds harmless. We have a weed that grows here in mass quantities, call Silver-Leaf Nightshade. It’s so wicked that a piece of stem 1/4 of an inch long will sprout a new plant. Also, this nasty devil has a ridiculous taproot of something like 6 to 10 feet, with siderunners. So know what you’re throwing in there, lest you come to regret it later.
Ok, that was fun. Now what do you wanna do?
