Applying Wood Ashes

Many of us have been told that we should use wood ashes  in our vegetable gardens as a fertilizer substitute.

Now, I heard that this may not be a good idea.  (Source: Mark Keaton’ Extension News: Be Cautious in using wood ashes)

Wood ash may  contain some important nutrients like phosphorus, (typically 7% and potash 23%)

However its not uncommon to see high levels of salts in the soil. Mark points out that their office has seen levels of 800 pounds of pure potash.

I agree with Mark, testing is the key.  Midwest Laboratories provides this type of testing and right now we are receiving a fair number of fertilizer samples for analysis.

Great article Mark!
