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 …

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.

Chemical Sealing Of Small Earth Dams Using Sodium Tripolyphosphate, R G. Pepper

Technical Bulletins

As the seepage rate of 3.1 mm/d was considered too high, sodium tripolyphosphate (STPP) was dissolved in the dam water in an attempt to disperse the clay and reduce the hydraulic conductivity. Application of STPP altered the original sealing layer at first and, as seepage progressed, a new seal started to form at a depth of 0.8 m below the batter. The seepage rate was reduced to 0.39 mm/d and the hydraulic conductivity of this new seal was 2.0 x 10-9 m/s.

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.
