Answer: Actually, wood ashes can be a valuable source of potash for crops, but if you add too much, the soil can become too alkaline for them. You want your soil pH to be around 6-6.5 for most crops. Also, if you burned other waste along with the wood, there maybe toxic contaminants in the ashes.<br><br>Your best bet is to have your soil tested, either with a home test like Burpee's, or through your agricultural extension service (ph# 610/696-3500). Then you'll know just what your soil needs. If you need a place to dispose of the ashes, your extension office can put you in touch with the Solid Waste District office in your county, and they'll be able to help.
