Soil Acidity Survey. Lime Responses In The Central Wheatbelt, P J. Dolling
Experimental Summaries - Plant Research
Introduction: In 1984 a project commenced to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia. To carry out some of the projects objectives a soil survey was carried out.
Aims: 1. To select nine sites for liming trials in 1985. 2. To obtain more information about the soil acidity problem in the medium rainfall region of W.A. 3. To determine if there is a relationship between the pH and aluminium content of the soil.
Survey details: Area covered - Katanning and Narrogin District Office (DO) areas. Sampling period - Mid …

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.

Annean Station Management Plan, A A. Mitchell
Resource management technical reports
Annean Station's carrying capacity has been estimated at 8,340 sheep on its 168,539 hectares. The halophyte pastures of Carnegie Land System were in good condition while those of Mileura Land System were in poor condition. The wandarrie pasture of the Belele Land System was in fair to poor condition. This system comnprises 34 per cent of Annean's area and is estimated as capable of presently carrying 2,900 stock.

Hydrological Studies In Soil Salinity, C J. Henschke
Hydrological Studies In Soil Salinity, C J. Henschke
Resource management technical reports
Investigations involved examination of near-surface indurated layers to investigate their role in saltland formation. It was found that groundwater could move readily through this layer due to the presence of macro-pores. Close examination of apparently impermeable pallid zone clays, shows that decayed tree roots and large diameter voids provide a continuous pathway for the veritical transport of saline water from deeper aquifers.

Pasture Research Programme For The Medium Rainfall Zone Of Wa, P. Dixon
Experimental Summaries - Plant Research
Pasture Research Programme for the Medium Rainfall Zone of W.A. - Species Selection and Management Related in Particular to the Ryegrass Toxicity Problem Since the early 1970's much of the ryegrass based pastures in the Pallinup region have been affected by Annual Ryegrass Toxicity (ARGT). Control of ryegrass by herbicides invariably leads to a reduction in the stock carrying capacity of the pasture since currently available legume species fail to grow or persist. This tendency is particularly evident on the hard setting loam soils of neutral to alkaline reaction. The aim of this project is to find alternative pasture species …
