Biochar is a soil amendment that is created by burning biomass in a low oxygen environment. It’s durable and porous structure is crucial for longer term water and nutrient retention, while at the same time preventing soil compaction and aiding drainage. Most importantly, it brings life back to your soil by providing a highly porous ecosystem for soil microorganisms to inhabit and flourish.
Applying biochar has been a method of soil improvement for thousands of years, with the ancient Terra Preta soils of the Amazon Basin being some of the oldest examples of the practice. The benefit of correctly applying biochar to your soil has a cumulative effect on plant health and output, with only one application needed per year.
