"Nitrous Oxide" project completed

Treatment with biochar reduces nitrous oxide emissions more strongly than two other forms of soil management.

​The "Nitrous Oxide" project conducted by Andreas Gattinger from the Research Institute of Organic Agriculture (FiBL) provides detailed information on the main factors influencing nitrous oxide emissions from soils and on the role of soil microbes. It also explains the impact of different soil management systems and cultivation methods as well as the effects of biochar treatments. The lowest nitrous oxide emission levels were achieved by applying biochar. But a number of questions still need to be answered before biochar can be recommended for use.
