Composting is a great way to reduce waste and create nutrient-rich soil for your plants. One of the most innovative ways of composting is by using an underground compost bin. In this guide, we will take you through everything you need to know about building and using an underground compost bin.

What is an underground compost bin?

An underground compost bin is a type of composting system that is built below the ground level. It is designed to take advantage of the natural heat and insulation provided by the soil, making it an efficient and effective way of composting organic matter.

Why choose an underground compost bin over other types?

There are numerous advantages to using an underground compost bin over other types of composting systems. One of the biggest benefits is its odor-free design, which makes it perfect for small urban gardens or areas sensitive to unpleasant smells. Also, an underground compost bin offers better protection from pests and rodents, due to its secure design below the surface.

What are the benefits of using an underground compost bin?

There are several benefits of using an underground compost bin, some of which include:

Healthy Soil and Plants

Using compost produced in an underground compost bin can improve soil health and plant growth. The nutrients provided by the compost help to feed and nourish the plants, reducing the need for synthetic fertilizers.

Odor-Free Composting

An underground compost bin doesn't produce unpleasant odors, which can attract pests and neighborhood complaints.

Reduced Waste

An underground compost bin helps to divert food scraps and garden waste from the landfill, reducing your environmental impact while creating rich compost.

What materials do you need to build an underground compost bin?

Building an underground compost bin requires some materials like:

• Cinder Blocks
• Gravel
• Landscape Fabric
• Compost Materials (such as food scraps, leaves, and yard waste)

Now that you know what an underground compost bin is and its benefits, let's head on to the next section, which explains how to build one.

Steps to Build an Underground Compost Bin

Step 1: Choose a Location and Dig a Hole

The first step in building your own underground compost bin is to choose a location and dig a hole using a shovel or a backhoe depending on the size of the bin. The ideal location should be easily accessible but out of sight.

Step 2: Build the Bin Structure

Once you have dug the hole, start building the structure for holding compost materials. You can use cinder blocks, bricks or even wood to make the walls.

Step 3: Add Composting Materials and Cover

After completing the structure, start adding compost materials such as kitchen scraps, leaves, and grass clippings, ensuring that there is enough moisture, and cover them with landscape fabric.

That's it; your underground compost bin is now ready to start decomposing organic waste into nutrient-rich soil!

How to Maintain and Use an Underground Compost Bin

Adding and Mixing Materials

Adding and mixing compost materials is an essential aspect of maintaining an underground compost bin. It would be best to add green and brown materials in equal parts and mix the pile regularly for efficient decomposition.

Temperature and Moisture Control

Using an underground compost bin requires consistent attention to temperature and moisture levels. To maintain optimal quality, ensure the bin is covered and has enough moisture content.

Harvesting and Using Compost

Once the materials have sufficiently decomposed, it's time to harvest the compost. Remove the top layer of soil and allow the compost to settle for a few days before using it in your garden as an excellent organic fertilizer.

Underground compost bins offer numerous benefits, including odor-free composting, reduced waste, and healthy plants. By following the steps outlined in this guide, you can build and maintain your own underground compost bin with ease!
