Abstract: This agricultural field utilization of tonnage quantities of a composite powder of coal combustion fly ash containing desulfurization residue prevents the escape of fugitive dust from the powder and effectively manages any cementitious tendencies of the powder, while raising the pH of the soil and adding plant nutrient elements to the soil. The powder is added to water at a weight ratio of 10:8-20 in an enclosed tank having a capacity of at least about 2,000 gallons. Mixing is conducted for at least about 5 minutes to form a soil treatment slurry composition easily flowable through a pipe of about 1-inch diameter. The treatment composition is applied on the agricultural soil before the composition hardens to a cementitious state, preferably by spraying directly from the mixing tank. The coating thickness is sufficient to amend just the top portion of the agricultural soil that supports plant growth, to elevate the pH above about 6.

Abstract: Two nuisance waste products, namely sewage sludge ash and water treatment lime, are mixed together to provide an agricultural soil treatment composition which enhances the nutrient value and raises the pH of the soil for improved plant growth while simultaneously minimizing the risk of wind blown ash dust.

Abstract: Two heretofore bothersome waste products, namely sewage sludge ash and water treatment lime, are mixed together to provide an agricultural soil treatment enhancing the nutrient value and raising the pH of the soil for improved plant growth while simultaneously minimizing the risk of wind blown ash dust. The ash is readily dryable and dusty but this feature is obscured by the water treatment lime which has a tendency to retain water. Mixing of tonnage quantities is conducted at a site near the facility generating the ash; and the mixture is transported to the agricultural soil to be treated and applied at a quantity between 2 and 70 tons of the water-containing mixture per acre of the soil. The application quantity is sufficient to raise the level of the soil-water pH of acid soil to a value of at least 6.5 but not above about 7.5 and insufficient to add to the soil more than the governmental limits for several heavy metals. Many nutrients needed for plant growth are contained in the mixture.
