Abstract

The project's primary aim was to produce fertilizers from steel manufacturing by-products such as LD slag, semicalcined dolomite and ammonium sulphate, using a computerized simulation process. The process was developed to determine the most efficient fertilization recommendation for pasture farming, agroforestry and forestry, with the aim of producing maximum quality end products and savings in agricultural production costs. The computerized system allows the application of formulae to maintain and/or improve the soil's capacity as a measured resource. The influence of these materials on the chemical composition of soil and grass was estimated, and the economic benefits of applying these new fertilisers to the soil evaluated. Standardized soil ecotoxicity and leaching tests were also carried out to determine the environmental impact of using fertilizers based on steel manufacturing by-products.
