Open bottomed compost bins are amongst the most commonly used forms of composting and are usually put on soil or dug into the earth. Here, we look at a few facts about these easy-to-maintain garden structures.
Fact #1 - Operation of Open Bottomed Bins
Open bottomed bins work similarly to other bins. They are fed with food scraps and brown materials like grass clippings, newspapers and leaves. Green material should be the first thing added to the bin so that it lies on the ground. Brown material is then added. This process can be repeated in alternate layers until full.
The mixture in the bin has to be turned occasionally. The easiest ways to turn the material require some type of garden tool like a pitchfork. The mixture is turned to the owner’s desire depending on how quickly they want compost.
Fact #2 – Benefits in Structure
The bins have sides and most have a lid. This structure allows the compost pile inside to retain more heat and moisture. This will allow the contents to process quicker than open piles.
It also takes less maintenance. Since the contents retain more heat and moisture, you do not have to turn or water the material as often. Open bottomed bins also prevent many intruders. The lid and sides prevent insects and animals from disturbing the contents.
Compost does not become an eye sore with these bins. The surrounding structure hides the compost so you do not have to look at a pile of decomposing material every time you’re outside.
Fact #3 -Beneficial to the Earth
With an open bottomed bin, there are many superb benefits. Nutrients will drain into the soil under the bin and this will enrich the soil under and around the it. It will also increase the water holding capacity of the soil.
Many who compost with open bottomed bins move the bins around their yards or gardens after each batch of compost so that more soil can enjoy the benefits.
Fact #4- Easy Access
Compost is much easier to access with an open bottomed bin. With tumblers and enclosed bins, the compost has to be dug out of the bin. An open bottom compost bin can be picked up to access the compost. The compost can then be distributed to planters, shrubs, trees and gardens.
Fact #5 - Beneficial to the Decomposition Process
Compost is created more quickly with open bottomed bins compared to ones that are completely enclosed. The open bottom allows microbes and worms to leave the ground and travel into the bin.
These organisms eat and break up much of the matter that is put into the bin and transform the matter into compost. Their movement increases aeration which is also needed for decomposition. While they increase the breakdown of green and brown materials in the bin, they also leave their own fertilizers in the compost making the soil that is produced much richer.
Fact #6 - Helps Recycle Waste
Like all compost bins, the open bottom bin will decrease what is thrown away in terms of green and brown waste. Composting typically reduces trash by 50% and uses waste in a constructive way.
