Plant root depth of tropical perennial grasses in a temperate environment

摘要：

The influence of perennial grasses on the soil water balance has been determined by measuring the pattern and depth of soil drying achieved by plant roots (Murphy and Lodge 2006).Pasture species having a greater plant root depth and an increased ability to use available soil water may produce more herbage mass, and so increase livestock production.The North‐ West Slopes region of New South Wales (NSW) is classed as a temperate environment, but it has warm to hot summers and a summer dominant rainfall distribution.Summer active species, such as tropical perennial grasses, may be suited to this environment to utilise available soil water during the summer season.
