What is Biochar?
Here is a definition found on Wikipedia:
Biochar is charcoal used as a soil amendment. Like most charcoal, biochar is made from biomass via pyrolysis. Biochar is under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions. Biochar thus has the potential to help mitigate climate change via carbon sequestration. Independently, biochar can increase soil fertility of acidic soils (low pH soils), increase agricultural productivity, and provide protection against some foliar and soil-borne diseases. Furthermore, biochar reduces pressure on forests. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years.

It's great for vege gardens. It has a liming effect on soil so good for sweetening acid soil and breaking down heavy clays. Biochar can be used as a mulch, mixed with compost, worked into the soil or spread on paddocks.
Biochar is also available in 40 litre bags and 1 m3 bulk bags. Discounts are available for purchases of 10 or more 40 litre bags.
