For one thing, the calcium percentage by weight varies considerably, from 7% up to 33%, depending on the type of wood that was burned. Also, wood ash will raise your soil pH, just like lime. However, wood ash is only about half as effective as raising pH as lime (you would need 2 pounds of wood ash to get the same pH change as 1 pound of lime).
