Going Underground: Compost Pit or Trench Composting

Organic Compost From a Compost Pit

If you're thinking about starting a compost pile, there are several things to consider; what type of composting structure to use, where to put it, and what to do with the finished compost product. Fortunately, composting can happen just about anywhere, and getting started can literally be as simple as heaping waste in a pile or burying it in a hole. There are advantages (and disadvantages) to composting without a container aboveground or underground. This article will examine the pros and cons of simply burying your organic waste in the ground.

Start Digging: Compost Pit

Compost Pit, (or trench composting) is about as basic as it comes: dig a hole, throw in your organic waste, and cover it with soil. You're done!

Composting underground utilizes what is known as anaerobic decomposition to break down the organic matter. Anaerobic decomposition works without oxygen, so there is no need for turning or aerating the matter. Anaerobic decomposition works much slower than the aerobic process that takes place aboveground.

Advantages of a Compost Pit

Putting your compost underground has some distinct advantages over aboveground composting:

A couple words of caution: If you bury your organic waste to compost underground, the anaerobic decomposition occurs slower, meaning it may take several months to a year before your waste breaks down into usable compost. Also, digging into an underground compost pit can be a stinky affair; unlike aboveground compost, the underground anaerobic critters doing the decomposing work emit stinky gases as a by-product of their hard work. Best that they be left alone to do their dirty work.

Where to Dig? You can dig your compost hole basically anywhere it will be convenient for you. Make sure you don't dig near underground utility lines. How big a hole you dig really depends on how much waste you need to compost.

If you're planning on using your finished compost product, remember that it won't be that easy to dig it up after you've buried it. If you garden, a great place to put your trench compost holes is between the rows of your garden. As the organic matter in the trenches rots, the nutrients become available for nearby plants.

Rotating trenches with planting areas each season will help develop healthy garden soil over time. Divide your garden space into 3 areas: a growing row for plants, a pathway row, and a row for trench composting. The following year, you can plant in the previous year's compost row. Doing this each growing season will improve the soil in the entire garden.

If you have the space available to you, and your ground isn't too hard to dig into , underground trench or pit composting can be an easy, viable method of composting for you.
