Soil Acidity And Liming In The Lower Great Southern, R N. Glencross, M. G. Clarke

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 …

Summary Of Rhizobium Experiments, J G. Howieson

Experimental Summaries - Plant Research

The main emphasis for rhizobial work in 1984 was on the acid tolerance of medic Rhizobium. The experimental programme in the field was greatly expanded to include testing of some 160 isolates collected from Sardinia in May 1984. Broadacre sowings of acid tolerant strain WSM 419 were undertaken as a preliminary step to its commercial release in 1985. Glasshouse work in 1984 was dedicated to a more intensive investigation of the factors contributing to the enhanced nodulating ability of M. polymorpha and M. murex on acid soils. As well, a simple technique for identifying acid tolerant strains of rhizobia in …

Sulphur Needs Of Crops And Pastures, J S. Yeates

Journal of the Department of Agriculture, Western Australia, Series 4

Sulphur deficiency has long been recognised as a potential problem of legume pastures in the higher rainfall areas (over 750 mm a year) of south-west Western Australia. Before the introduction of granulated superphosphate (about 1970), sulfer deficiencies commonly developed in spring on susceptible soils despite autumn applications of superphosphate (containing about 10.5 per cent sulphur).

In loww and medium rainfall areas sulphur deficiency is rarely reported, at least partly because of annual superphosphate applications. However large areas of the sandy-surfaced soils of Western Australia would become sulphur deficient for pastures and crops if sulphur inputsd in fertilisers were substantially reduced. …

One of the causes of reduced plant yields on acid soils is aluminium toxicity. because barley is extremely sensitive to this mineral, a project started last year to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia.

This article discusses some of the background information on the project and its aims.

Modifying Fertiliser Practices, J S. Yeates, D. M. Deeley, M. F. Clarke, D. Allen

Journal of the Department of Agriculture, Western Australia, Series 4

If modified fertiliser practices are adopted phosphorus losses from the Peel-Harvey catchment can be reduced. Farmers can save money on fertiliser applications and the need for more expensive catchment management measures to reduce algal pollution of the estuary will be avoided.

Research data available so far indicate that, with farmer co-operation and the use of the new slow release fertiliser New Coastal Superphosphate, long-term phosphorus application rates can be reduced by 30-40 per cent - and possibly even halved - without lowering agricultural production. This will also reduce phosphorus loss to drainage water.
