Potassium from Fruit Skins
I have been looking for a good organic source of potassium (things like greensand and kelp meal are not available here).
Referring to the useful table at
I notice that many of the best sources of potash are fruit/vegetable skins *but* only their "ashed" forms are listed. Does the burning process actually change the potassium content, and if so, by how much? If I were to just bury fresh skins under my leaf mulches, how long would it take for the soil to be ammended in K by an appreciable amount?
