Dear Tom
The continuing interest continue to give me hints. What I have read (mostly from Japanese trials) indicates the results are there but spotty. There is no way to quantify 'and increase' in a general sense. For the amount of money and effort there are alternatives. Regards Crispin +++++++++ Crispin, Benefits tend to be specific to soils and circumstances. There has been lots of research by forest soil scientists in the US West in recent years (Montana, Idaho, Oregon). I know of a couple of private companies that are doing field trials. The best documentation for the benefits of char is referenced on the website of the International Biochar Initiative (www.biochar-international.org). We also have considerable information at www.biochar.bioenergylists.org Several biochar-in-forest-soil papers have been presented at the many regional, national and international biochar, agronomy and soil science conferences.
