Summery of the Final EU-COST and ANS Biochar Symposium 2015

End of September 2015, the Joint International EU-COST and ANS e.V. Biochar Symposium was hosted Hochschule Geisenheim University which was visited by roughly 190 researchers, practitioners and stakeholders from Europe and overseas. ..more

Joint International Biochar Symposium 2015

Geisenheim (Germany), from 28th to 30th September 2015
The Joint International Biochar Symposium 2015 aims at understanding mechanisms that enable beneficial and safe biochar implementation, by uniting the two often separated, co-existing “worlds” of practitioners, stakeholders and applicants with biochar scientists for inspiring exchange. ..more

The keynote speakers

We are proud to announce nine excellent keynotes of some of the world's most renown biochar scientist. ..more

Session 1: Sequestration

“Time matters” - biochar persistence in soil and its effects on SOC stocks
From the start of biochar research, the value of biochar has been seen in its ability to allocate carbon from the fast biogeochemical cycle to slower cycling which was often termed “C sequestration”. This ability is intimately linked to the persistence and fate of biochar-C in soils (mineralization, particle disintegration, vertical transport etc.). ..more

Session 2: Technology

Biochar Production Technology: designing biochar properties
Basic as well as more advanced analyses showed that there is no such thing as “biochar” but that there are many different biochars. Their differing characteristics have to be taken into account to understand the function of biochar in soil and to explain nutrient dynamics, interaction with plants and microbes, carbon persistence etc. ..more

Session 3: Risks

The Janusface of Biochar: Risk of pollution versus pollution remediation tool?
Pyrolysis performed under inappropriate processing conditions may produce biochars loaded with pollutants. These need to be quantitatively identified to facilitate their avoidance. But biochar (the Janus face) can also strongly sorb environmental pollutants when they come into contact with biochar. ..more

Session 4: Horticulture

Biochar use in horticulture: Designing biochar substrates for reduced peat use and improved plant health
Two promising pathways of biochar use in horticulture exist to date: (A) Using larger doses for reducing peat use, and (B) using very small doses to improve plant health in soilless growth media. ..more

Session 5: Agriculture

Biochar use in temperate and tropical agriculture, animal husbandry and organic fertilizer management
In initial biochar field experiments large doses of pure, untreated biochar have been applied. While temperate soils and crops were on average unaffected the results found in tropical, particularly degraded soils are more promising. ..more

Session 6: GHG

Biochar use for reducing GHG (N2O, CH4) emissions in soils, substrates and animal production
Early on it has been found, and has now been confirmed by meta-analysis, that biochar addition to soil can reduce N2O emissions, while the effects on CH4 fluxes (production and oxidation) are less clear. However, in field experiments the N2O-reducing effect is smaller and sometimes absent. ..more

ANS call for paper

Geisenheim (Germany), from 28th to 30th September 2015
The third day of the Joint Biochar Symposium 2015 of the EU COST Action biochar and the ANS e.V. is dedicated to the practical use of biochar in environmental technology, resource management, agriculture and (bio)energy production and to stimulating the intensive exchange between practitioners, users and scientists from all EU COST Action countries, as well as international... ..more
