The effects of waterponding on the reclamation of degraded scalds in the semi-arid rangelands of N.S.W.
Soil erosion as a result of extensive overgrazing and the subsequent reduction in vegetation cover is seriously affecting the long term ecological and economic sustainability of the grazing industry. Where this occurs on saline-sodic soils, the loss of the Ai horizon and consequent exposure of the silty A2 horizon, results in the creation of an impervious crust over the clayey B horizon. The resultant scald is an extremely hostile environment for plants. Currently 10%, or the semi-arid...[Show more]
