The Buzz on Biochar

Biomass charcoal (biochar) has become a soil health buzz word, but what is it exactly? Biochar is a carbon-rich solid material left over when organic matter (like wood, dry leaves or grasses) are burned at an extremely high temperature in the absence of oxygen – a process called pyrolysis. 

For use in gardens and landscapes, biochar should be added and mixed with your compost or potting soil before it is applied. The porous surface of biochar provides habitat for beneficial microbes that thrive in compost, protecting them from predation and drying while providing carbon for their energy needs. It also helps to retain soil moisture, minerals and nutrients for plant health and adds structure to sandy soils.

One great feature of biochar is that it remains in soil for hundreds and potentially thousands of years. Go ahead and add some biochar to your compost and soil mixes – it even helps sequester atmospheric carbon, PRFCT all around!
