|Culled trees have various uses.|
|Decomposition is slow and releases GHG.|

At La Pedregoza we are in the process of constructing 3 large Adam Retorts, based on a design development by a German Ph.D. by the name of Chris Adam. Our goal is to produce on average 1 metric ton of charcoal per day and to then charge it with organic material so that we will have substantial biochar with which to improve our soils (see the soil sample in Part 1). In Part 4 of this series we will discuss the charging of the biochar and its application to the soil, as well as how best to use wood ashes, which are another by-product from making charcoal.
