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. …

Alternative Pasture Species For Deep Sands, D A. Nicholas

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

Although the climate of the swan coastal plain between Perth and Bunbury is suitable for growing a range of pasture species, some soil types greatly limit this range.

Pasture species commonly grown in the South-West, such as subteranean clover and annual ryegrass, can only be grown successfully on the better soils of the coastal plain - the loams, yellow sands and Joel sands. On the freely drained, deep, infertile Gavin sands such species rarely persist because of the soil's poor water holding capacity, and its water repellency and its poor ability to retain nutrients.

Molybdenum Deficiency In The Wheatbelt, M M. Riley

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

The trace element molybdenum is needed in very small amounts in nitrogen metabolisms of crops and pastures. One of the projects that started as a result of the overall soil acidity research programme was the examination of molybdenum deficiency on acid soils throughout the South-West of Western Australia.

Barley Production And Soil Acidity, P J. Dolling, W. M. Porter

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

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.

Although much of the research since 1982 …
