Influence Of Water Supply On Farm Productivity In The North-Eastern Wheatbelt, E J. Hauck

Resource management technical reports

In the area with reliable reticulated water supplies, average what yield, average wool production and average number of sheep per pastured hectare showed a positive correlation with annual rainfall in all but one year. By contrast, in the area served by on-farm water supplies only, average wheat yield and annual rainfall were strongly correlated, whereas average wool production and average number of sheep per pastured hectare showed a weaker correlation with annual rainfall. These correlations suggest tt on farms with a reliable water supply, livestock numbers have been adjusted annually to ensure optimum utilisation of available feed in all seasons.

Fodder Trees And Shrubs For High Rainfall Areas Of South Western Australia, Daya Patabendige, P R. Scott, Edward C. Lefroy

Resource management technical reports

In south Western Australia, the lack of good quality feed in late summer and autumn is a major constraint to livestock production. This feed gap is usually filled by costly supplementary hand feeding of grain or hay. The ability of some trees and shrubs to provide good quality forage during summer and autumn has generated interest for many years (Corbett, 1951; Everist, 1969; Snook, 1987;Oldham et al., 1991, Lefroy, 1991). The dual benefits of reducing the need for supplementary hand feeding and deferring the grazing of annual pastures until they are well established has recently led to the recognition of …

Land Resources Study Of The Carnarvon Land Conservation District And Part Of Boolathana Station, Western Australia, M R. Wells, C D M Keating, J A. Bessell-Browne

Land resources series

A survey of the land resources of 36,343 ha covering the Carnarvon Land Conservation District and an adjoining portion of Boolathana station was conducted to assist future land use planning and management. This report describes the soil, landform and vegetation conditions of land units shown on an accompanying 1:50,000 scale map. These land units are components of land systems previously mapped at 1:250,000 scale for the Carnarvon Basin by Payne et al. (1987). As part of the study, further, more detailed land resource mapping and land capability assessments were conducted at specific locations. Land use planning and management considerations arising …
