Technical Bulletins
The Ivanhoe Plain was divided into two geomorphic provinces. The principal difference between the provinces is the time during which pedogenesis occurred. The crcking clay soils of the northern province are generally more highly leached than their younger counterparts in the southern province. Sixteen land units are identified as distinct from soil units. These units give cognizance to vegetation and topographical features as well as soils.

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

Seepage Interceptor Drains For Reducing Waterlogging And Salinity, Don Mcfarlane, Jim Cox
Journal of the Department of Agriculture, Western Australia, Series 4
Shallow interceptor drains can reduce waterlogging on sloping sites. Such drains will more than pay for themselves from the increased crop yield. Recent work has shown that these drains also decrease salinity so that they are cost-effective in the long as well as the short term.

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

Some farmers have used level W1SALTS banks to control surface zvaters above areas affected by ivaterlogging and salinity. Because the amount of waterlogging has been reduced, crop yields have increased downslope of some banks. However, the banks divert fresh surface water into deeper salty groundwater and, in the long term, worsen salinity. This article details an investigation of the effect of level WIS ALTS banks on saline groundwaters and discusses alternative methods of preventing the waterlogging of saline areas.

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), …

Stunt patch disorder of lupins.
Location: Merredin.
Studies on the disorder have been initiated (89ME1 and 90ME5) on two sites 15 km south of Merredin. This report will summarize data on:
1) The soil;
2) Soil strength and lupin emergence on 90ME5; and
3) Soil chemical and physical characteristics associated with the patches on 89ME1 (investigations by A. Thomson for B Sc (Agric) dissertation).

Trial 88EB18
Location: East Beverley Research Station
Impeded early root growth.
Using aerial photography and crop growth data from previous seasons we identified areas on the site where crops grow well or poorly. One of the factors implicated in the poor growth areas is impeded early root growth (see Belford et al. and Tennant et at., 1990 Experimental Summaries, this section). Here we describe the problem and outline possible causes.

Response By Stylosanthes Hamata And S. Scabra To Phosphate On Three Soils In The North-Kimberley Of Western Australia, A Mcr Holm, Mario F. D'Antuono
Resource management technical reports
Legume herbage mass was maximized after two or three years application of 50 kg/ha double superphosphate for both Verano and Fitzroy on Red earth soils and for Fitzroy on Yellow lateritic soils. There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.

Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder
Resource management technical reports
Details the situation on the station so that the demonstration and research programs can be designed and the effect of the treatments assessed. Past work on the station has been briefly summarised and the results of geophysical surveys and additional drilling are given. Surveys of electromagnetic terrain conductivities have shown where salinity is most serious at present. The most deeply penetrating method may have identified areas likely to developing salinity in future.

Resource management technical reports
A land unit map of the region has been prepared at a scale of 1:50,000. Additional maps of climate, surface and groundwater supplies and existing land use have also been prepared at smaller scales. The capability of each of the land units to support grazing, market gardens, vineyards, orchards and forestry has been assessed. The limitations for housing on small rural lots have also been evaluated. Describes the methods by which the survey was undertakenand will be primary of use to the technical user.

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 …

Darling Range Rural Land Capability Study, Peter Donald King, M R. Wells
Land resources series
This report presents land resource mapping and land capability assessments for rural residential and associated agricultural activities at a scale of 1:50,000 over 100,000 ha of rural land in Perth's eastern metropolitan hills area. The study area is bounded to the west by the Great Northern, Albany, Roe and South Western highways, and extends north, east and south to the boundary of the Perth metropolitan area. Using the broad framework of landform-soil associations defined by Churchward and McArthur (1980), discrete mapping units have been delineated by reference to landform and soil characteristics likely to affect future land uses. They provide …
