Biochar is charcoal created by pyrolysis of biomass, and differs from charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage.[1] Charcoal is a stable solid rich in carbon content, and thus, can be used to lock carbon in the soil. Biochar is of increasing interest because of concerns about climate change caused by emissions of carbon dioxide (CO2) and other greenhouse gases (GHG). Carbon dioxide capture also ties up large amounts of oxygen and requires energy for injection (as via carbon capture and storage), whereas the biochar process breaks into the carbon dioxide cycle[clarification needed], thus releasing oxygen as did coal formation hundreds of millions of years ago.[citation needed]

What are the likely benefits of biochar?

In some soil types and with certain crop species, some biochars have been shown to:

increase water holding capacity of the soil

increase biomass (crop) production

increase soil carbon levels

increase soil pH

decrease Aluminium toxicity

decrease tensile strength

change microbiology of the soil

decrease emissions from soil of the greenhouse gases CO2, N2O and CH4

improve soil conditions for earthworm populations

increase CEC, especially over the long-term

improve fertiliser use efficiency

It should be noted that the wide variety of biochar feedstock materials, process conditions and applications leads to a huge and diverse range of responses that are often contradictory. Some biochars have been shown to have no influence on some of the factors noted above; some biochars have been shown to have adverse effects on crop productivity. More research is required to verify the observed effects and to distinguish beneficial from detrimental biochar products.

Studies thus far have shown that the greatest positive effects of biochar applications have been in highly degraded, acidic or nutrient-depleted soils. Thus, biochar research is of particular relevance in the Australian context, as many Australian soils exhibit very low nutrient and carbon levels, and are at risk of acidification.

Biochar the new frontier.

Welcome to Biochars a blog about Biochar.

Our goal is to bring you the latest information concerning biochar. Our format will be link based and we will try to direct you to more authoritative sources of information.

Biochar is a shortened name for Biological Charcoal, its uses are many and varied. The ancient civilisations knew about it. Our civilisation is rediscovering it. Biochar can help with pollution and toxins, Biochar can help with drought and nutrient supply. In fact there is so much research being done about Biochar that it might surpass the Oil and Coal industries as a premium environmentally friendly fuel for all of mankind.
So don’t be slow hop right in and learn all about Biochar.

Our first port of call is based in Australia and its called the
A website dedicated to one mans journey into discovering biochar informative and very readable.
