GREEN BY-PRODUCTS FOR AGRICULTURAL LANDS
EXTENSION SPECIALIST & PROFESSOR
ALABAMA COOPERATIVE EXTENSION SYSTEM
Before commercial fertilizers and ground agricultural limestone, by-products, mainly manures, were the main soil amendment used. In the early 20th Century industrial by products that could improve crop production became popular. Some of these were ammonium sulfate, a by-product of coking, and basic slag, a by-product of the steel industry. With our heavily industrialized society and urban living, many more by-products are potentially available that have beneficial use on agricultural lands either as nutrient sources, soil amendments, or soil liming materials. We will feature a few of these that have been tested over the years and are being used successfully in Alabama rather than burying them in an expensive landfill. Some of those described include a potassium bicarbonate solution (3-0-11 grade fertilizer) from a chemical industry, paper mill by products including boiler wood ash, lime wastes, and biochar, alum sludge from waste water treatment facilities, municipal biosolids, food processing wastes, and cotton mill wastes.
