wood stove

Is it true that ash from a wood stove is good for a lawn?
I was told that ashes from a wood stove was good for a lawn. Can anyone answer me?
Yes and no. In very limited quantities spread out over a large area, it will add potassium to your lawn. Too much, and you will cause a chemical burn to the grass.
Caution should be used when handling wood ash:
Protect yourself as you would if you were handling household bleach or any other strong alkaline material. Wear eye protection, gloves and a dust mask.
Do not use ash from burning trash, cardboard; coal or pressure-treated, painted or stained wood. These materials contain potentially harmful chemicals, The glue in cardboard contains boron, an element that can inhibit plant growth if applied in excess.
Do not scatter ashes during windy periods.
Do not mix ash with nitrogen fertilizer as ammonium sulfate or ammonium nitrates or urea. These fertilizers lose their nitrogen as ammonia gas when mixed with high pH materials such as wood ash. For a lawn, wait at least a month after wood ash is applied before putting down a nitrogen fertilizer to allow for the soil to reduce the alkalinity of the wood ash.
