   i save and use the ashes from the bbq pits and backyard campfires on   
   flower beds. i'm learning to be more scientific about growing what i eat,   
   though. i have no idea how much potassium in the ashes. the Espoma   
   potash had 60% potassium by weight. from soil test results and   
   recommendations it's simple math to calculate how much to amend to the   
   soil. not enough leads to deficiencies, too much is a waste.
