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.

本研究在强酸性土壤上开展了为期三年的深松试验，以评估一系列无机土壤改良剂在改良亚表层酸性、促进作物生长及提升产量方面的效果。本研究首次在田间对一种新型产品MgSi进行了试验，该产品由70%的杜姆巴纯橄榄岩（Doonba dunite）与30%的F70超细石灰（F70 superfine lime）复配而成。
