Pure Biochar (2 cu. ft.)


Biochar is the secret to the famously fertile soils of the Amazon. It was discovered some time ago that the Amazon soils were so ripe for planting because of the large concentration of biochar. Biochar has since been researched heavily and proven to increase plant growth and crop yields while at the same time making the soil more healthy.

In the earth, biochar acts like a sponge, holding more water for the plants roots and allowing more microorganisms to thrive. This is how biochar makes your soil come alive! On top of that, biochar is a carbon negative product, which means that by using it in the soil you are helping to reduce the amount of greenhouse gases in the air. Grow more food to feed yourself, while cleaning up the earth and air around you. Now that’s something to feel good about!

Thank you for choosing carbon negative soils. We appreciate your continued support and please let us know if we can do anything to improve your experience.

Product Description


When Adding to Compost (recommended)

Biochar needs to be inoculated before it is used. That’s why we recommend mixing it with compost and letting it cure for at least 2 weeks. Then it can be mixed into the soil in the same way our Ancient Elements Soil Amendment is used.

When Adding to Soil

1. Add 1-1.5 inches of biochar to the soil.
2. Cover the Biochar with as much if not more high quality compost and water well. This step will allow the water to run through the compost to form a compost tea that can be absorbed by the Biochar, thereby ‘charging’ it.
3. Work the compost and biochar into the top 10 or so inches of soil and water well.
4. Allow the soil to come to equilibrium for two weeks, continuing to water regularly.
5. Hold off on watering until the soil feels just moist, not wet or dry.
6. You are now ready to plant, following specific package or plant tag instructions.
