Biochar

Biochar generated as a by-product of combined heat and power gasification is classified as waste, for which the UK does not currently have a safety protocol for use in the open environment. The UEA is working with the Environment Agency to determine environmental tolerance limits, in order to assess potential environmental risks (ex: PAH contamination). My preliminary study aimed to measure any negative plant growth effects by amended soil with high concentrations of biochar under controlled laboratory conditions.

Arborists in Chicago are studying the results of biochar on trees growing in urban soils that are typically hostile to trees. This research is part of a larger urban-soils study that includes applications of biochar in greenhouse and field plot settings at The Morton Arboretum. The Bartlett Tree Research Laboratories have also been testing adding biochar to the soil mix when planting trees. More information and media coverage of this study about biochar and urban tree care can be found on the Bartlett Tree Experts web site.

Gasifier Charcoal as a Substitute for Vermiculite in Container Growing Media

P Pine Seedlings in 25% BiocharP Pine Seedlings in 25% Biochar
Our second trial of biochar as a substitute for vermiculite in container media for growing tree seedling has proved successful. These tests are by a private nursery to determine if charcoal from a gasifier heating system can be used in container growing media.

Third year results: Fourth Corner Nurseries Soil/Biochar Study

This study predates the coining of the term biochar and I claim grandfather rights to use the word charcoal.

Summer 2009 Biochar plot studySummer 2009 Biochar plot studyresults are showing some trends I have had difficulty measuring with the last two years of cropping these plots. The use of buckwheat, a short season cover crop plant makes a visual view of performance reflecting nutrition, quite vivid. In spite of the dips in the plots due to deer browse.

This image is a merged sequence of pictures taken at same distance. Background may be confusing because of perspective. These plots are the first set, (south end), of treatments laid out in a systematic way. Results from the north set are similar and will be presented in a final poster

This plot study included: compost ( a wood based commercial compost of sewage solids)
charcoal 1 ( about 1/2 inch minus), charcoal 2 ( powder from John Flottvik's pyrolyser).
fertilizer: a complete, chemical fertilizer
