 about biochar

Biochar is produced by heating biomass in a low oxygen environment and is a very porous material that can be used as an agent for soil improvement. To be recognized as biochar, the material must pass a number of material property definitions that relate both to its value (e.g., H/Corg ratios relate to the degree of charring and therefore mineralization in soil) and its safety (e.g., heavy metal content).

Kelpie Wilson has published a very good article in the Ithaka Biochar Journal about  "How Biochar Works in Soil"(double click to read)

 the approach

While there are many high tech ways of producing biochar, of equal importance are mid and low tech methods to make biochar production and use viable for everyone. NZ Biochar has both independent and collaborative research currently underway in New Zealand and in Thailand. A particular focus is on making and using biochar within the same location to maximise both the agricultural benefits and carbon sequestration, e.g. small scale farming systems on degraded soils in subtropical and tropical regions.
Working with farmers and practitioners to develop and promote best practice use of biochar is an important focus.
