Land Systems Of The Kimberley Region, Western Australia, A L. Payne, N Schoknecht
Technical Bulletins
The Land Systems of the Kimberley Region Report describes and maps the landscapes, soils and vegetation of the Kimberley region. This report is a consolidation of surveys carried out by different organisations, across different areas of the Kimberley, since the 1940s. The Kimberley region, as defined in this bulletin, covers 330 070km². The report categorises the Kimberley region into 111 land systems. Under each land system, the report identifies the vulnerabilities of those areas, and provides recommendations on how to achieve sustainable use. The report also publishes pasture types for the entire region and the grazing potential for each pasture, …

Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane
Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane
Technical Bulletins
Separate estimates of the effect of waterlogging on cereal yields were made using rainfall and crop yield statistics, and remote sensing. Both methods showed that waterlogging costs tens of millions of dollars each year in lost crop production in the Upper Great Southern Statistical Division. The costs will be over $100 m in wet years. Losses in pasture production are likely to be of a similar magnitude, but are harder to quantify.

Soils Of The Ivanhoe Plain, East Kimberley, Western Australia, J M. Aldrick, M H R Van Cuylenburg, P W. Moody, B A. Wren, A J. Clarke
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.
The Soils Of The Salmon Gums District, Western Australia, George Henry Burvill
The Soils Of The Salmon Gums District, Western Australia, George Henry Burvill
Technical Bulletins
Most of the soils are grey and brown solonized soils. The subsoils, to about 2 m, are calcareous sandy clays with limestone rubble, but there are three main surface variations: sandy surfaced, 5-30 cm deep, passing abruptly to the sandy clay subsoil with lime nodules. The Circle Valley sand and Scaddan sand are major types. Scaddan sand has a domed subsoil clay. Powdery calcareous sandy loam; and clay loam and clay with some lime in the subsoil, but less than in 1 and 2.

Wheat And Barley Experiments On The Kumarl Soils At Salmon Gums, D A. Collins, Michael D A Bolland, R D. Fletcher
Technical Bulletins
The water-holding capacity of these soils, and their location in a low rainfall area combine to make them marginal for producing grain. In contrast to sowing wheat on ley pasture, mechanically fallowing the year before planting markedly improved grain yields by 1.3 to 4 times.

Plant Collections For Saltland Revegetation And Soil Conservation, A J. Clarke, T C. Swaan, C V. Malcolm
Technical Bulletins
In 1967, during an overseas plant exploration trip, seeds of plants of reputed salt tolerance and forage value were obtained from seven countries. Since 1971, over 600 plants have been added to the original collection of 343 plants already under observation for suitability for forage production in saline and arid areas. Additions to the test programme since 1971, include shrubs from Algeria; Argentina; Australia; Chile; England; Iran; Israel; Libya; Morocco; Netherlands; Russia; South Africa; Spain; Tunis and the United States of America. This Bulletin includes details of all plant collections from 1966 to December 1983.
Chemical Sealing Of Small Earth Dams Using Sodium Tripolyphosphate, R G. Pepper
Chemical Sealing Of Small Earth Dams Using Sodium Tripolyphosphate, R G. Pepper
Technical Bulletins
As the seepage rate of 3.1 mm/d was considered too high, sodium tripolyphosphate (STPP) was dissolved in the dam water in an attempt to disperse the clay and reduce the hydraulic conductivity. Application of STPP altered the original sealing layer at first and, as seepage progressed, a new seal started to form at a depth of 0.8 m below the batter. The seepage rate was reduced to 0.39 mm/d and the hydraulic conductivity of this new seal was 2.0 x 10-9 m/s.

Cereal, Pasture Legume And Water Supply Prospects At Forrestania : Results Of Experimental Work East Of Hyden, Western Australia, T E. Mcdowell, M G. Mason, J W. Gartrell, William J. Toms, I A F Laing
Cereal, Pasture Legume And Water Supply Prospects At Forrestania : Results Of Experimental Work East Of Hyden, Western Australia, T E. Mcdowell, M G. Mason, J W. Gartrell, William J. Toms, I A F Laing
Technical Bulletins
The agricultural potential of the Forrestania area appears at least equal to that of much of the settled eastern wheatbelt. The scrubplain soils of the Forrestania area have an average yield potential of at least 1 000 kg/ha wheat and carrying capacity of 1.8 to 3.7 sheep per hectare on improved pastures. The use of clover ley rotations would maintain these levels of potential yield. Partial crop failures caused by adverse seasonal conditions could be expected 10 years in every 100.
Soil Potential For Groundnut Production At Kununurra, Western Australia : Report Of A Survey Conducted In January 1979, J C. Dixon, Richard J. Petheram
Soil Potential For Groundnut Production At Kununurra, Western Australia : Report Of A Survey Conducted In January 1979, J C. Dixon, Richard J. Petheram
Technical Bulletins
Production of groundnuts in trials on irrigated Cockatoo Sands near Kununurra have been sufficiently encouraging for a soil survey to be requested of three small areas possibly suitable for commercial release. It was anticipated that between 1 000 and 1 200 ha would be necessary in the immediate future for development of five farms for groundnut production. The survey was begun in November 1978 to: classify the sand soil types. determine the potential of these types for with groundnut production. examine possible relationships between soils and vegetation to be used when selecting land for groundnut production.
The Agricultural Potential Of Owingup Swamp. 1. Soil Survey Of Owingup Swamp. 2. Comparison Of Owingup And Grasmere Swamps, L T. Jones, C V. Malcolm, James P. Fallon, Department Of Agriculture And Food, Western Australia
The Agricultural Potential Of Owingup Swamp. 1. Soil Survey Of Owingup Swamp. 2. Comparison Of Owingup And Grasmere Swamps, L T. Jones, C V. Malcolm, James P. Fallon, Department Of Agriculture And Food, Western Australia
Technical Bulletins
The two swamps, Owingup and Grasmere are practically identical with regard to soil conditions. Grasmere swamp however has been cleared and used for agriculture for some 60 years while Owingup swamp is as yet unalientated. Soils on both swamps consist of mainly organic diatomaceous clay. Findings of the survey indicate that some 2000 acres at Owingup swamp would be suitable for vegetable growing following clearing and draining.
