Rodrigo,
Am interested in this as well but have not experimented with it. My parents and grandparents were subsistance garderners and used wood for heat. All the ashes were put on the dormant garden in the fall and winter and tilled into the soil in the spring. My other rememberance is that we "Ate very well" and had vegtables to sell. I know also that ashes from burned "Corn Cobs" is said to be 40% Potassium. We had lots of corn cobs as we fed our horses corn. I need to raise my potassium levels on my cymbidiums also - and have not decided just when and how to do it. Adjustment of a commercial fertilizer would need to be done carefully. Just adding another ingredient may cause chemical changes or seperation and percolation of the salts that are already in the fertilizer. This is a problem I am looking around for a solution too.
