Title: Fly Ash Utilization Program Phase II Greenhouse Project
Author: Sheard, R.W.; Warren, C.J.
Abstract: Ontario Hydro's Nanticoke generating station, located in the Haldimand-Norfolk region on the shores of Lake Erie, annually produces about 600,000 tonnes of fly ash. Initial estimates suggest that al least 660,000 tonnes of fly ash produced at the Nanticoke station could be applied as a liming agent to local acidic agricultural soils. The objective of the project were: (1) under greenhouse conditions determine the influenece of fly ash, applied as a liming material to two representative soils of the Haldimand-Norfolk region, on the growth and chemical composition of corn, alfalfa, wheat and soybeans; (2) to determine changes at monthly intervals in soil pH values, extractable cations, hot water soluble boron, and acid extractable metals for ash amended soil; and (3) to measure the changes in the moisture release characteristics resulting from the addition of fly ash.
