Horticultural Charcoal/Biochar for Plants Contains …, Bishan

When used in soil building, charcoal is often referred to as “biochar.”

Biochar can decrease nutrient leaching, lower soil acidity, and reduce the amount of water and fertilizer used on your vegetables and flowers.

Charcoal is highly porous and contains many of the nutrients found in the organic material from which it was made. Charcoal increases the soil’s ability to hold onto plant nutrients and beneficial soil microbes by slowing or reducing the leaching of nutrients by rain or watering.

The low density of charcoal lightens heavy soils, which allows better root growth, increasing drainage and allowing air into the soil.
