Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Harvested And Grazed Lupin Stubbles On Following Wheat South Carrabin., J W. Bowden
Experimental Summaries - Plant Research
Location: South Carrabin lease block
Harvested and grazed lupin stubbles on following wheat. Trial 86M8
This trial is difficult to analyze statistically because of the treatment changes induced by sheep breaking in to some of the plots. Further, lupin grain yields were not very high and so differences between harvested and unharvested treatments are not large. Also the grazing intensity was not very severe (except on the unintentionally grazed plots) and so the effect of grazing is also relatively small.

Residual value of phosphate fertilizers.
Location: South Carrabin Block of Merredin Research Station.
4th successive crop on new land. Trial has shown that the effectiveness of the different types of rock phosphate were about the fifth to one tenth as effective as the fresh (triple) superphosphate applied in 1984. The effectiveness of the superphosphate, decreased by 60 between year 1 and 2, and by a further 10-15% by 1987. This experiment will continue as pasture for 1988 and 1989, and will be re-cropped in 1990. The experiment is also assessing soil testing for P. but soil test data …

Experimental Summaries - Plant Research
86KA71, Pasture legumes improve the feeding value of summer pastures in a mediterranean-type environment by maintaining the protein intake of grazing animals over the dry summer period, much of which comes from the ingestion of legume burr (A.D. Wilson and N.L. Hindley, 1968). Some of the most important species of pasture legumes to have been released commercially are Trifolium subterraneum (sub.clover), Medicago truncatula (barrel medic) and Medicago polymorpha (burr medic) (D.B. Purser, G.B. Taylor and W.J. Collins, 1987). What little information is available on the feeding value of these species suggests that barrel medic pod (H. Brownlee, 1973) and dry …

The Effect Of Soil Acidity On Barley, P J. Dolling, T. D. Haines
Experimental Summaries - Plant Research
Three liming experiments were established to confirm previous estimates of the critical soil acidity level for barley. Two experiments studying the effect of depth of incorporation on the effectiveness of lime, established in 1986, were continued in 1987.
The results from the three liming experiments established this year supported the conclusion that barley is affected by soil acidity at pH's around 4.2 and 4.3 (CaC12) and that depth of this acid layer is important.
Significant lime responses were obtained at the Katanning depth of lime incorporation site but conclusions can not be made because of possible mixing of …

Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter
Journal of the Department of Agriculture, Western Australia, Series 4
The humble woodchip, widwly used as a soil mulch in Western Australian gardens, is set tto take a new role as a dust inhibito in assembly yards used to hold live sheep for export.
Research by the Department of Agriculture's Soil Conservation Service Branch has shown that, of the materials tested, woodchips were the most effective in preventing dust being generated. Wind speeds had to approach a "near gale" before dust developedfrom the protected soil.
The use of woodchips, therefore, provides a practical alternative to stabalising the soil and preventing an environmental problem associated with one of the State's valuable …

An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry
Technical Bulletins
The inventory and condition survey of rangelands in the Carnarvon Basin, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1980 and 1982, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers …

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.

Investigation Of A Saline Valley On Allandale Research Farm, D J. Mcfarlane, R Engel, A T. Ryder
Investigation Of A Saline Valley On Allandale Research Farm, D J. Mcfarlane, R Engel, A T. Ryder
Resource management technical reports
Geophysical surveys and drilling were used to investigate a saline valley on Allandale Research Farm. These techniques showed that the geology is controlling the location of two main areas of saline seeps and they identified another area at risk of increased salinity. They were also used to obtain information on the groundwater system and to assist in making management recommendations.
Electromagnetic terrain conductivity surveys showed that the most saline soils occurred upstream of a cross-cutting magnetic anomaly caused by a dolerite dyke. A seismic survey showed that the anomaly coincided with a bedrock rise. This bedrock rise restricts groundwater flow …
