FACT SHEET: Biochar in Compost

Digital version of the USBI Biochar In Compost Fact Sheet created in 2022

Improve compost and save money.

Adding biochar activates the composting process by enhancing the activity of microorganisms, which raises the temperature, reduces composting time and speeds up stabilization of the compost.

The quality of biochar-compost improves soil health and can boost crop yields.

Research shows that that adding 5% to 10% by volume biochar at the start of the compost process can generate the following benefits:

• Speed up the composting process by 20% through better aeration of the pile and increasing microbial activity
• Capture odors
• Generate a compost with higher nutrient because biochar retains nitrogen
