Composting is an excellent way to reduce waste and create a nutrient-rich soil amendment for our gardens. However, not all compost is created equal, and some methods can be more effective than others.

One way to supercharge your compost is by incorporating biochar into the mix!

Biochar is a type of charcoal that is created by burning organic matter in the absence of oxygen. This process creates a highly porous material that can hold onto water and nutrients, making it an ideal addition to compost.

When we add biochar to our compost pile, we are essentially creating a habitat for beneficial microorganisms. These tiny creatures are responsible for breaking down organic matter into a form that plants can use. By providing them with a home in the form of biochar, we are encouraging their growth and activity, which can speed up the composting process and create a more nutrient-rich end product.

While incorporating biochar into your compost pile may seem like a daunting task, it is actually quite simple. There are several methods for doing so, including mixing it in with your compost materials, layering it between compost layers, or even creating a separate biochar compost pile.

By experimenting with different methods, you can find the one that works best for you and start reaping the benefits of biochar composting.

What is Biochar Composting?

When we talk about Biochar Composting, we are referring to the process of adding biochar to our compost pile. Biochar is a type of charcoal that is produced from organic materials, such as wood and other plant matter. It is created through a process called pyrolysis, which involves burning in a low-oxygen environment. This process produces a stable, carbon-rich material that can be beneficial for soil health.

When we add biochar to our compost pile, we are enhancing the composting process. Biochar can help to improve the speed and quality of our compost by increasing the amount of carbon in the pile. Since biochar will tend to bind to nutrients that would otherwise leach out of the pile, adding biochar to the compost pile can help to create a more balanced compost that is rich in nutrients.

One of the benefits of using biochar in our compost pile is that it can help to reduce greenhouse gas emissions especially in the form of carbon dioxide. Biochar is a stable form of carbon that can remain in the soil for hundreds or even thousands of years. This means that when we add biochar to our compost pile, we are effectively sequestering carbon in the compost and hence in the soil.

In addition to this, biochar can also help to improve the water-holding capacity of the soil. This is because it has a high surface area, which allows it to absorb and retain water more effectively. This can be particularly beneficial in areas that are prone to drought.

Finally, the porous nature of biochar provides composting microorganisms a place to live. These microorganisms are responsible for breaking down organic matter into the base nutrients to use to feed the plants. Biochar provides these microorganisms with a place to live.

Overall, incorporating biochar into our compost pile can be a great way to improve the health of our soil and create a more sustainable gardening practice. By doing so, we can help to reduce greenhouse gas emissions, improve the quality of our compost, and create a more resilient garden ecosystem.

Benefits of Biochar Composting

Improves Soil Health

When added to soil, biochar in compost can improve soil health in several ways:

1. Nutrient retention: Biochar has a high surface area and a porous structure that allows it to absorb and retain nutrients such as nitrogen, phosphorus, and potassium. This makes these nutrients available to plants over a longer period of time, reducing the need for fertilizers.

2. Water retention: Biochar can also improve soil's ability to retain water. The porous structure of biochar allows it to hold onto water, reducing runoff and helping plants access water during dry periods.

3. Microbial activity: Biochar can act as a habitat for beneficial microbes that help break down organic matter and make nutrients available to plants. This can improve soil fertility and reduce the need for synthetic fertilizers.

4. pH balance: Biochar has a neutral pH, which can help balance the pH of acidic or alkaline soils, making it more suitable for plant growth.

Biochar compost does all of these things by improving soil structure. This, in turn, helps to increase aeration and drainage, which can be essential for keeping our plants healthy. Biochar is a highly porous material that can absorb and retain water and nutrients. This means that when we add biochar to our compost pile, we are creating a nutrient-rich environment that can support the growth of healthy microbes and hence healthy plants as we add the completed compost to our soil.

Reduces Greenhouse Gas Emissions

Based on current findings, the benefits of adding biochar to the composting process may include reduced rates of greenhouse gas emissions.

‘The main gasses we think of when discussion greenhouse gasses are Carbon Dioxide (CO2) Methane (CH4) and nitrous oxide (N2O). These are common greenhouse gases that are produced during the composting process.

However, the addition of biochar to the compost pile has been shown to reduce these emissions within your gardening system. This means that we can reduce our carbon footprint by incorporating biochar into our composting process.

Here are how each of the greenhouse gasses are reduced via biochar incorporation into compost:

1. Carbon sequestration: Biochar is a stable form of carbon that can remain in soil for hundreds or even thousands of years. When biochar is added to compost, it becomes part of the soil organic matter and helps to sequester carbon from the atmosphere. This helps to reduce greenhouse gas emissions by removing carbon dioxide from the atmosphere.

2. Methane reduction: Composting organic materials can produce methane, a potent greenhouse gas. However, the addition of biochar to compost can help to reduce methane emissions by providing a habitat for methane-consuming bacteria. These bacteria convert methane into carbon dioxide, which is a less potent greenhouse gas.

3. Nitrous oxide reduction: Composting can also produce nitrous oxide, another potent greenhouse gas. However, the addition of biochar to compost can help to reduce nitrous oxide emissions by improving soil health and reducing the need for synthetic fertilizers. Synthetic fertilizers can contribute to nitrous oxide emissions when they break down in soil.

Overall, the incorporation of biochar in compost can help to reduce greenhouse gas emissions by sequestering carbon, reducing methane and nitrous oxide emissions, and improving soil health.

Reduces Waste

Another benefit of using biochar compost is that it can help to reduce waste. When we add biochar to our compost pile, we are creating a more efficient system for breaking down organic matter. This means that we can compost more quickly and effectively, which can help to reduce the amount of waste that we produce. By reducing waste, we are helping to create a more sustainable future for ourselves and for future generations.

Biochar incorporation into compost can help reduce waste in several other ways:

1. Diverting organic waste from landfills: Organic waste, such as food scraps and yard waste, makes up a significant portion of municipal solid waste. When this waste is sent to landfills, it decomposes anaerobically and produces methane, a potent greenhouse gas. However, when organic waste is composted with biochar, it can be diverted from landfills and turned into a valuable soil amendment.

2. Reducing the need for synthetic fertilizers: Biochar is a rich source of carbon and nutrients, and when added to compost, it can help to improve soil health and fertility. This can reduce the need for synthetic fertilizers, which are often produced using fossil fuels and can contribute to greenhouse gas emissions.

3. Improving soil structure and water retention: Biochar has a porous structure that can help to improve soil structure and water retention. When added to compost, it can help to create a high-quality soil amendment that can be used to improve soil health and reduce erosion.

Overall, the incorporation of biochar into compost can help to reduce waste by diverting organic waste from landfills, reducing the need for synthetic fertilizers, and improving soil health. This can contribute to a more sustainable and environmentally friendly approach to waste management.

In summary, incorporating biochar into our composting process can have many benefits. It can improve soil health, reduce greenhouse gas emissions, and reduce waste. By using biochar compost, we can create a nutrient-rich environment that can support the growth of healthy plants while also reducing our carbon footprint and promoting sustainability.

How to Make Biochar Compost

Composting with biochar is a great way to improve soil health and reduce waste. Here are the materials and step-by-step instructions to make biochar compost.

Materials Needed

• Compost materials (e.g. kitchen scraps, yard waste, etc.) We are aiming for a 25:1 to 40:1 Carbon : Nitrogen ratio.

• Biochar (5-10% by volume)

• Water

• Compost bin or pile

Step-by-Step Instructions

Step 1: Prepare the compost pile or bin. If using a bin, make sure it has holes for aeration and drainage.

Step 2: Add the compost materials to the bin or pile. Make sure to have a good mix of green (nitrogen-rich) and brown (carbon-rich) materials.

Step 3: Wet the compost materials with water as each layer is applied. The compost should be moist, but not too wet. A good rule of thumb is when squeezing the compost, you should only be able to squeeze out a few drops of water.

Step 4: Add the biochar to the compost pile or bin. Use a ratio of about 5-10% biochar to the compost materials. Mix the biochar and compost materials together well.

Step 5: Let the compost pile or bin sit for a few weeks to a few months. During this time, turn the compost regularly to aerate it and speed up the composting process. If the compost pile begins to get dry, make sure to add more water to keep the proper ratio.

Step 6: Once the compost is ready, use it in your garden or as a soil amendment. The biochar in the compost will help improve soil health and retain nutrients.

Remember, composting with biochar is a process that takes time and patience. But the end result is well worth the effort. By incorporating biochar into your compost pile, you can create healthy soil that will support healthy plants and a thriving ecosystem.

Tips for Using Biochar Compost

Amount to Use

When using biochar in compost, it is important to get the right amount. Adding too much biochar can potentially make the compost too dry, while adding too little can make it too wet. A good rule of thumb is to use about 5-10% biochar by volume. This means that for every 10-20 parts of compost, you should add 1 part of biochar. You can adjust this ratio based on the moisture content of your compost and the type of biochar you are using. Smaller grained biochars will go a long way!

When to Apply

The best time to add biochar to your compost is during the initial stages of composting or pile creation. This is when the compost is still hot and actively breaking down. Adding biochar at this stage can help improve the structure of the compost and provide a habitat for beneficial microorganisms. You can also add biochar to finished compost before using it in the garden. This will help improve soil structure and fertility.

How to Store

Biochar Compost is a stable material that can last for centuries in the soil. However, it is important to store biochar compost properly to prevent it from getting overly wet or contaminated. Store a pile of biochar compost covered with a tarp to prevent excess moisture from running through it.

You can also store biochar compost in a closed container to prevent it from getting contaminated with other materials.

Whatever your means of storing, keep the stored biochar compost out of the sun to ensure the microbiology is not killed by excessive heat.

By following these tips, we can effectively incorporate biochar into our composting process and reap the benefits of improved soil fertility and structure.
