Track 2-09: Soil Quality, Biology and Plant-Soil Interactions
Description
Lucerne (Medicago sativa) is one of most productive perennial species in southern Australia. However, productivity is severely restricted under acid soils (Irwin et al. 2001). Fenton et al. (1996) reported that lucerne performs 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 lucerne during the 3rd cycle of the experiment from 2004 to 2009.
