Amelioration of subsoil acidity using inorganic amendments

A three year deep ripping experiment was conducted on a highly acidic soil to test how effective a range of inorganic soil amendments were to ameliorate subsoil acidity and improve crop growth and yield. A novel product, MgSi (a blend of 70% Doonba dunite and 30% F70 superfine lime), was tested in the field for the first time.
