Biochar Benefits
- Improves Germination
- Stimulated Plant Growth
- Increases Water Retention
- Enhances Soil Fertility
- Increases Soil Microbial Activity
- Builds Carbon Reserves in the Soil
When BioChar Source is added to soil, several things happen:
First – beneficial soil microorganisms multiply and interact with plant roots.
Next – these microbes speed up the break-down of crop residues and increase nutrient cycling.
When combined with BioChar Source, the plants, the microbes, and the nutrients all come together to work 24/7 for your garden!
