Dairying In W.A., Department Of Agriculture And Food, Western Australia
Bulletins - 3000 - 3999
Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per hectare. Commercial dairy farming in Western Australia is confined to the south-western corner of the State, south of Perth, extending in a 50-kilometre-wide strip along the coast to 50 kilometres …

The survey was conducted to gain basic information about the agricultural land use of the Brockman River Catchment. The University of Western Australia Faculty of Agriculture was interested in the area as a compact, agriculturally diverse area close to Perth which was, therefore, suitable for filed studies. The Department of Agriculture, Moora Office was interested in this study as a framework within which to improve its extension services in the area.
Both parties cooperated in investigations of the area by providing data and equipment. Field work was carried out in summer 1973-74 and data compiled by an agricultural science student …

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie
Fisheries Research Reports
The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.
The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Of the four time of planting trials twodefinitely showed superiority of earlier seeding (73BA5, 73E6). The two trials in the Southwest (73BR14 and 73MT7) gave highest yields with June sowing compared to May. Three trials (73BR14, 73E6 and 73BA5) appear to have a Variety x Time interaction for plant density, but no definite trend for either Uniharvest or Unicrop although later sowing reduced plant density. Seeding rates in excess of 82 kg/ha gave the highest yields in all trials. The rate of seeding experiments (73BA5 and 73MT7) show that the best crop density for yield (graph) lies between 8 and …

The Soil Conservation Service : Its Basis Of Co-Operation With Landowners, G W. Spencer, J. E. Watson
Journal of the Department of Agriculture, Western Australia, Series 4
The Soil Conservation Act of 1945 set up within the Department of Agriculture a Soil Conservation Service under the control of a Commissioner of Soil Conservation.
The Service aims to promote types of land use which will conserve the soil and prevent or overcome soil erosion. It also aims to educate landholders and the public generally in the aims and practice of soil conservation.
This article relates mainly to farm land activities, and in particular the co-operation of the Service with individual primary producer landholders for the prevention and control of erosion on their land.

Soil Structure Changes Under Wheatbelt Farming Systems, T C. Stoneman
Journal of the Department of Agriculture, Western Australia, Series 4
A review of 14 years of Department of Agriculture research into the effects of wheatbelt fanning practices on soil structure reaches the general conclusion that cultivation and grazing practices influence soil structure, and that structure can be improved by soil amendments and pasture growth.
Little data has been obtained to relate plant growth to improved soil structure, as measured.

Summary Of 1972 Seasonal Results "Decide" Superphosphate Rates On Pastures, J. W. Bowden
Experimental Summaries - Plant Research
A total of 53 pasture trials were topdressed. Of these, 37 trials were quantitatively assessed at different times during the growing season. Of the 15 wheat trials sown, only four trials gave useful results because of multiple drilling techniques used on most trials. Until the trial results have undergone comprehensive statistical analysis, no conclusions can be drawn. about the levels of response or "optimum" rates of superphosphate application at individual sites. However, because of the very short growing season in 1972 responses were generally poor. It appears that nil superphosphate application would have been optimum for animal production in the …
