As the Pine Tree Power web site explains, "The wood ash from wood chip fired power plants is an environmentally sound, nutrient rich soil supplement. It sweetens soil by reducing acidity, and supplies calcium, potassium, phosphorus, magnesium and various trace elements essential to plant growth. Under a state approved plan, the ash that Pinetree Power produces is available to local farmers with ten or more usable acres. Private haulers deliver free ash to farmers, who spread it on fields or plow it into the soil. This encourages growth while keeping farmer's costs down and crop prices competitive. The New Hampshire Bureau of Public Health and the U. S Department of Agriculture regulate the ash program. " |
