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!
