I am curious if anyone has used wood ash from a power plant for a lime or soil amendment source? If so, what results were you seeing and what crops were you using it on? The ash has a low heavy metal content. Did you run into any problems spreading it and what type of spreader were you using? Did you blend it with other products to ease the spread? Are there any other concerns or do you have any additional advice that I should look for when handling and using this product?
