This is a great article about how Biochar can help mitigate the effects of climate change. Here's an extract from the article featured on the Hartley Botanic website- follow the link below to view the full story.

Biochar is a kind of upmarket charcoal, similar to that used in barbecues, but in granular form, which is made by burning woody, carbon-rich plant wastes – such as garden prunings – in an oxygen-starved process called pyrolysis. The result is a highly stable form of almost pure carbon, with a porous, honeycomb-like structure, which can halt any loss of carbon dioxide back to the atmosphere for hundreds or even thousands of years.The use of biochar results in more fertile soil and compost with increased microbial life (beneficial mycorrhizal fungi and other soil life love to inhabit biochar’s microscopic pores), which retain water and nutrients better in dry spells, which grow great plants and which – to boot – can help turn down our global thermostat.
