Leschenault Peninsula : A Study Of Land Resources And Planning Considerations, Veronica P M Oma
Resource management technical reports
Leschenault Peninsula is a fragile coastal dune barrier north of Bunbury, Western Australia. Most of the landforms are highly, or potentially highly, unstable and are not capable of sustaining tourism uses other than walking tracks. Minor areas close to Leschenault Inlet are more stable and could be developed for a range of tourism uses including accommodation and day tripper facilities. However, much of the Peninsula is highly degraded and susceptible to wind erosion, while disposal of acid-iron rich li id effluent from the Laporte (SCM) works in lagoons located within the dunes, has contributed to the visual degradation of the …

Rangeland Surveys : A Basis For Improved Land Use, P J. Curry, Alan Payne
Journal of the Department of Agriculture, Western Australia, Series 4
In mis 1988, the Department of Agriculture started a three-year programme to assist pastoralists in the Murchison River catchment to update land management planning of their stations. This Project, which is funded by the National Soil Conservation Program, will use interim results from a recent rangeland survey which has investigated and mapped the grazing recources throughout the region.
Elsewhere in Western Australia's pastoral areas, information on the productive potential of each area - and the management problems inherent for each class of land - are being used to help pastoral managers of Soil Conservation Districts rehabilitate degraded areas. This information …

New Block Badgingarra Rs Late Time Of Seeding., J. W. Bowden, R. J. Lunt
Experimental Summaries - Plant Research
Trial 89BA33,
Location: Badgingarra
Based on a 1.5 t/ha potential yield, the strategic treatment was planned to be 120 kg urea/ha 4WAS. However, the crop was poorly established and so NH4NO3 was used in the hope of getting better tillering than would be possible with the slower release urea source. Gambling on equal dollars to urea for 2/3 N, but believe that twice as effective.
DAP was used to place nitrogen with the seed in case there was no rain of significance after seeding. This nitrogen (only 5 kg/ha) was probably lost with the rains of 20-28/7/89 (50 mm). Urea …

Trials : 88BY26, 88PE34, 88MD35
Control of Rhizoctonia solani infection of potato stems and daughter tubers was demonstrated by preplanting applications of tolclofos-methyl (RIZOLEX TM) to either cut or round seed tubers. Yield of tubers from cut seed treated with Rizolex was increased over that of cut seed cured before planting bu not when seed was cut and planted the same day. Crops grown from round seed treated with Rizolex yielded higher than from untreated round seed.
Surface sterilization of seed tubers with Sodium hypochlorite was effective in reducing stem damage but not in reducing daughter tuber sclerotes. This indicates …

Pasture Species Evaluation On Acid Wodjil Soil - Machine Sown Plots., Bradley Nutt
Experimental Summaries - Plant Research
Trial 89TS38
Location: East Latham
The very low seed yields are a reflection of the dry winter conditions experienced in 1989. The Rose (T. hirtum) and Cupped (T. cherli) clovers appear to be a more promising option for this difficult soil type compared to other species. Paros yellow serradella performed well considering the trial site is located in a very dry area. The burr medics would not be an option on these acidic soil types because of nodulation failure; which should become evident in the regenerating swards.

Current recommendations for pasture species in the medium rainfall zone has not included species mixtures for paddocks with varying soil types. These trials (three in total) are designed to test the hypothesis that legume species mixtures are more productive and persistent in the long term than monocultures, across three soil types and three different cropping/pasture rotations (continuous pasture, 1 year pasture : 1 year crop rotation, 2 years pasture : 1 year crop rotation).
