I have been burning beetle kill pine for 3 months (about 5 cords) using a Seton W-130 gassifier and have generated about 40 gallons of ash - the very fine gray stuff). I have been told that the ash can be used for fertilizer and have put some out and noticed another use - snow melting. I threw ash onto about 80 sq ft of my yard which melted the snow. Since then the area has been snow free. Works better than salt!! So, now how to not track it into the house??? What is everyone doing with their ash and about how much are you generating?
