UK: the Big Biochar Experiment
Oxford Biochar, Summer, 2011
Oxford Biochar is sponsoring a giantexperiment to test the effectiveness of Biochar in standard garden plots all across Britain.
The web site does a nice job of explaining what biochar is, and showing the benefits of adding it to your soil. Then it asks home gardeners to set up 2 plots, one a test, and one a control. Add the biochar, and record data about what types of things they added to both plots, the pest control needed and the yields from that plot are. It looks like it will do a nice job of seeing whether regular gardeners are likely to see results from biochar in the first year.
It's too late for spring planting, but it's just the right time for summer planting for fall crops. Information about the plot test, and tips for getting started and recording data are on the web page: http://www.bigbiocharexperiment.co.uk/get-started.html
