Dave Dzwilewski from Gail Materials in Los Angeles sent me some interesting articles on biochar and water. Like a lot of people, his concern is whether adding biochar to the soil will or will not decrease the need for irrigation. There are a lot that show it will, but one of the better ones showing it won't comes from a group from several northern European countries. You can find the study by searching for the title of the report:
Effects of biochar on water retention in the Interreg Biochar: climate saving soils field trials
As with all these studies, it really depends on which biochar you use and the soil type. But this study was thorough and collected the right data.
PS: Thanks to everyone that came to our reception for Frank Shields and Jeff Licht. We had a lot of people excited about biochar and a good time.
