Scientists believe that soil improved by biochar is more efficient, retaining critical nutrients such as magnesium, calcium , phosphorus and nitrogen.

  • How do you use biochar fertilizer?

  • To use biochar fertilizer, dig the chunks into your soil or mix them into your compost pile. Although charcoal briquettes from a barbecue may seem like a good source of biochar, the charcoal usually includes solvents and paraffin that may be harmful in the garden.

  • Why is Biochar a carbon negative activity?
