At a talk about biochar, it was explained that it should be made at high heat. The way it works is to provide habitat for beneficial bacteria, and it didn't work without compost being added at the same time. Regular charred wood doesn't cut it. The biochar does not break down even after 1000's of years. The biochar + compost combination added to urban fill produced astounding results. Plants grew tremendously instead of being stunted as usual in that environment. Too bad we can't make the stuff in the city. We have plenty to burn, but I doubt the fire department would go for it.
