Activated Charcoal in Compost: Benefits and How to Use It
Activated charcoal has been increasingly gaining popularity as an additive in composting. But what is activated charcoal, and why should you consider using it? In this post, we'll explore the benefits of activated charcoal in compost and how to use it effectively.
What is activated charcoal?
Activated charcoal is a form of carbon that has been treated with oxygen to create a highly porous surface area. This porosity allows activated charcoal to absorb and trap toxins and impurities in air or liquid. Due to its excellent adsorption properties, activated charcoal is commonly used in health supplements, water filters, and even beauty products.
Why use activated charcoal in compost?
Due to activated charcoal's ability to absorb toxins and impurities, it can also improve compost quality. Composting involves breaking down organic matter into nutrient-rich soil. However, sometimes, this process can lead to unpleasant odors, pest infestation, excessive moisture, and nutrient loss.
How does activated charcoal benefit compost?
Adding activated charcoal to compost can neutralize odors, increase nutrient retention, and improve soil drainage. Let's look at each benefit in more detail.
Benefits of Activated Charcoal in Compost
Neutralizes Odor
The breakdown of organic matter in composting can produce unpleasant smells, making it less desirable to manage. Adding activated charcoal can absorb odors by trapping volatile organic compounds responsible for bad smells. This makes composting not only tolerable but can also make it favorable.
Improves Soil Drainage
Adding activated charcoal to compost can significantly improve the soil drainage by maintaining and stabilizing moisture content level in the soil. Excessive moisture can promote bacteria growth, which can be harmful to plants.
Increases Nutrient Retention
Just like how activated charcoal absorbs toxins and impurities, it can absorb nutrients in compost and prevent them from being lost through leaching. This helps to ensure that your plants receive adequate nutrition from the soil.
How to Use Activated Charcoal in Compost
To use activated charcoal effectively in compost, follow these simple steps:
- Select the right type of activated charcoal
- Powdered activated charcoal
- Granular activated charcoal
- Air purifying bags
- Mix activated charcoal with compost materials
- Apply the mixture to your garden soil or potted plants
Types of Activated Charcoal for Composting
Powdered Activated Charcoal
Powdered activated charcoal is an excellent form of activated charcoal for composting as it has a greater surface area for better adsorption properties.
Granular Activated Charcoal
Granular activated charcoal comes in small-sized pieces and is an excellent option when you want to sprinkle evenly on top of the compost without mixing it.
Air Purifying Bags
Air purifying bags use a combination of activated charcoal and other materials to adsorb odors and purify the air. These can be hung in areas where odor control is needed, such as a compost bin.
Activated charcoal is a versatile and cost-effective additive that can improve the quality of your compost. By adding activated charcoal to your compost, you'll provide numerous benefits for both your plants and overall soil health.
FAQ
