Abstract

Lucerne (Medicago sativa) is one of most productive pe-rennial species in southern Australia. However, productivity is severely restricted under acid soils (Irwin et al. 2001). Fenton et al. (1996) reported that lucerne per-forms poorly if soil pH was below 5 and exchangeable aluminium was over 5%. It is estimated that there are 24 m ha of acidic subsoil in southern Australia (Dolling et al. 2001). A long-term liming experiment, 1992 to 2010, aimed to ameliorate subsoil acidity via a vigorous liming program (Li et al. 2001). This paper reports survival of lu-cerne during the 3rd cycle of the experiment from 2004 to 2009.
