One of the main reasons why farmers need fertiliser is to reduce the amount of acidity in the soil. It might seem counter-intuitive, but steel slag has exactly the right chemical composition to do this. Slag has been used in agriculture for some time, notably in the USA, Germany, and France, and it has proved both effective and cost-efficient.
