Présentation
In southern Australia, extensive clearing of the native vegetation in the past century has enabled annual crops and pastures to be established, to the benefit of the whole Australian economy. The largely unforseen consequence of this change in vegetation has been a change in the hydrology. The deep drainage component of the water balance has increased ; principally because the shallow roots of the annual vegetation do not dry the soil profile to as great a depth as did the predominantly perennial native vegetation. If this problem is to be redressed, deep-rooted perennial agricultural species need to be incorporated into the farming systems. The most common species recommended for this role is lucerne (Medicago sativa L.)
