Water Erosion On Potato Land During The 1983 Growing Season Donnybrook, D J. Mcfarlane
Resource management technical reports
Soil losses over a three month period varied from 10 to 49 mm.. Soil loss was most highly correlated with length of slope of the plots. Other important factors appeared to be slope angle and soil textures. Grade furrows appear to be the best method of breaking-up long slope lengths. The low capacity of the furrows requires them to be on grades of about 4 to 4 per cent to prevent siltation and overtopping during high density storms.

Sources Of Lime In The South-West, I M V Brown
Sources Of Lime In The South-West, I M V Brown
Journal of the Department of Agriculture, Western Australia, Series 4
Many Western Australian farmers topdress or incorporate lime into their acid soils to neutralise them and to improve crop or pasture yields. Most use pulverised limestone or limesand which is cheap and relatively easy tospread.
Agricultural lime isdefined as "any fertiliser used principally for the purpose of reducing soil acidity and having calcium carbonate or magnesium carbonate, or both, as its main ingredients".
Less extensive sources of liming material are found in scattered inland areas where deposits of calcrete have been formed by the weathering of calcium-rich rock and also in association with internal drainage systems.
Magnesite, generally formed by …
Soil Acidity In The Eastern Wheatbelt, W M. Porter, I. R. Wilson
Soil Acidity In The Eastern Wheatbelt, W M. Porter, I. R. Wilson
Journal of the Department of Agriculture, Western Australia, Series 4
In Western Australia parts of the sandplain of the eastern wheatbelt are very acid and produce poor crops, It was not until the late 1970s that the effect of soil acidity on the productivity of the sandplain soils was examined in any detail.
Since then researchers have learnt a great deal about the nature of soil acidity in the eastern wheatbelt sandplain soils and can suggest management options for farmers.
This article discisses the problem of the very acid soils. It does not deal with the moderately acid, medium textured soils of the eastern wheatbelt. Although the acidity of these …

Soil Types And Drainage, Eric Bettenay, N. J. Schofield
Journal of the Department of Agriculture, Western Australia, Series 4
At least 90 per cent of the phosphorus entering the Peel-Harvey estuarine system comes from land cleared for agriculture, most of it from the coastal plain. These soils are naturally deficient on phosphorus and sulfur and this is supplied in superphosphate, which contains about 10 per cent phosphorus and 1 percent sulphur.
However, rain leaches some of this applied phosphorus from the land into drains and rivers which flow into the estuary. In 1981, farmers in the Harvey River-Mayfields Drain catchment lost the equivalent of 1,300 tonnes of superphosphate into the estuary. Between them they have in effect spent $120,000 …

The 1984 experimental programme was a continuation of that started in 1981. The programme was aimed at evaluating the major herbicides in current use for cereals as well as new herbicides against the recommended varieties at three main sites, these being Wongan Hills, Merredin and Mt Barker. In addition Stage 4 breeding lines were evaluated against the same herbicides but only at Wongan Hills. The herbicides used and their rates and time of application are presented in Table 1. Herbicides were applied at both the recommended and twice the recommended rates of application, except in the breeding line trial where …

Journal of the Department of Agriculture, Western Australia, Series 4
In the 375 to 750 millimetre rainfall area of the Lower Great Southern, reports of loss of subterranean clover from established pastures, reduced carrying capacity for sheep and increasing soil acidity lead to the establishment in 1981 of a research programme into the effects of soil acidity on pasture productivity in that region.

Foliar Disease Of Wheat, A. G. P. Brown
Experimental Summaries - Plant Research
Wheat leaf diseases were at much reduced levels in 1984. This may have been caused by prolonged summer rain prematurely setting off dispersal of spores and also initiating microbiological breakdown of stubble residues. No survey was carried out in 1984 but a good indication of the seasonal effect can be gained by noting that in the spray-timing experiment at Badgingarra disease levels were extremely low until the end of August some 90 days after sowing.

84M5, 84M6, 84M7. Location: Merredin Research Station Merredin, Western Australia. Three experiments were conducted to measure the productivity and water use of alternative wheatbelt crop species on contrasting soil types in a dry mediterranean environment. Crop species investigated were wheat, barley, cereal rye, narrow leafed lupin and field pea. These were grown on three contrasting soil types, a red-brown earth, a sandy loam over clay and a deep loamy sand; all soils occurring within close proximity to each other. Detailed measurements were made of meteorological conditions, dry matter production, leaf area, root growth, soil water profiles, light interception and plant …
