Fisheries Research Report No. 83 - The Western Rock Lobster Fishery 1985/86, R. S. Brown, E H. Barker

Fisheries Research Reports

The 1985/86 annual catch of the western rock lobster Panulirus cygnus, totalled 7,191,968kg (Australian Bureau of Statistics (ABS) ), a drop of 1,774,497kg (19.8 per cent) on the 1984/85 season. The value of the 1985/86 catch was approximately $94M based on ABS figures. This drop in catch was almost entirely the result of lower puerulus (first post larval stage, approximately 9 to 11 months old) settlement three to four years before (i.e. 1982/83 and 1981/82). The fall in catch was accompanied by a drop in fishing effort (total number of pot lifts) of 12.1 per cent on the previous season …

Geraldton Rural-Residential Land Capability Study, R A. Dye, A M E Van Vreeswyk, Geoff Allan Moore

Land resources series

With a growing population in the Geraldton area, there is a demand for rural and coastal subdivision to provide for rural residential development and intensification of agricultural activities. Future land use planning for land use change and management of land to overcome existing land degradation problems should be based on land capability. This study provides a semi-detailed (1:50,000) soil and landform inventory for the immediate zone around Geraldton, south from Coronation Beach to Cape Burney along the coast, 13.7 km inland in the north and 7.6 km inland in the south. Eight land systems were identified in the land resource …

Busselton, Margaret River, Augusta: Land Capability Study, Peter J. Tille, Neil Clifton Lantzke

Land resources series

The study was done to ensure that information on the area's land resource, and its capability, is available for land use planning. This information will assist planners to make decisions which can allow for the optimal development of the land while avoiding land degradation or land use conflicts. A map showing the distribution of land units defined according to soil type, topography, drainage and wind exposure was prepared at a scale of 1:50,000. From this map a smaller scale, less detailed land systems map was drawn. Land capability, the ability of land to sustain a specific use without undesirable on-site …

Preliminary Groundwater And Salinity Investigation In The Eastern Wheatbelt. 4. Kitto's Hillslope, Tammin - 1985-90, Richard J. George Dr

Resource management technical reports

The investigation revealed that a deep, brackish to saline groundwater system and dolerite dyke, contained within the saprolite were responsible for the secondary salinity; the annual discharge of water and salt at the seep from the damp groundwater system was about 2800 kL and 17 tonnes respectively; and the water-tables were not rising and that the most appropriate management of the site was to plant salt tolerant forage plants in combination with trees.

The 1989 Saltland Survey, Richard George

Journal of the Department of Agriculture, Western Australia, Series 4

In March 1989, the Australian Bureau of Statistics (ABS) surveyed farmers in Western Australia to determine the area of previously arable land that was now too saline for conventional agriculture. Farmers reported that 443,441 ha, or 2.83 per cent, of the 15.7 million hectares of cleared farm land in south-western Australia, was saline. This was an increase of about 180,000 ha on the 1979 survey figure.

The worst affected areas were in the 350 mm to 600 mm rainfall zone and included the Shires of Tammin (9.26 per cent arable area saline), Katanning (7.96 per cent), Goomalling (7.93 per cent), …

Shallow Drains For Reducing Waterlogging And Salinity On Clay Flats, Don Mcfarlane, Tim Negus, Arjen Ryder

Journal of the Department of Agriculture, Western Australia, Series 4

Flooding, waterlogging and salinity are problems which commonly occur together on the broad valleys of the wheatbelt. Drainage lines often become poorly defined once they reach the valleys and flood waters spread out, causing inundation and waterlogging. This excess water needs to be controlled because it contributes to salinity

Waterlogging Limits Growth On Duplex Soils, Bob Belford, Miles Dracup, David Tennant

Journal of the Department of Agriculture, Western Australia, Series 4

Duplex soils - soils with a sandy topsoil overlying a clayey subsoil -are ividespread in Western Australia's agricultural areas (see map). These soils are potentially highly productive, but crop growth is variable and the soils can become waterlogged. Work on a duplex soil site near Beverley has shoivn that the soil ivaterlogs where the permeability of the clay is low, and that this permeability varies ividely over the site. Waterlogging accounts for an average of half of the variation in wheat yields on this site; surprisingly, lupins have so far appeared less sensitive to waterlogging- The Department of Agriculture and …

Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson

Journal of the Department of Agriculture, Western Australia, Series 4

One of the more difficult aspects of growing potatoes in Western Australia is controlling soil insect pests. These pests have become more troublesome because the highly effective and persistent organochlorine insecticides previously used to control the main soil pests, African black beetle and whitefringed weevil, were deregistered for agricultural use in 1987. Entomologists from the Department of Agriculture and CSIRO in Western Australia are collaborating to develop new management strategies for these pests that rely less on the use of chemical insecticides
