Groundwater Test Pumping In The Tambellup Townsite, Louise Hopgood Dec 2003

Groundwater Test Pumping In The Tambellup Townsite, Louise Hopgood

Resource management technical reports

Previous studies have concluded that the township of Tambellup is underlain by a perched aquifer. Test pumping and groundwater modelling indicated that groundwater pumping may be an effective way of protecting townsite infrastructure by lowering the water table beneath the town. This report presents results of the test pumping and provides likely bore yields, prediction of pumping influence and likely optimum production bore spacing.


Groundwater Investigation On Victoria Location 8565, East Binnu, Russell John Speed Nov 2003

Groundwater Investigation On Victoria Location 8565, East Binnu, Russell John Speed

Resource management technical reports

Describes a drilling investigation undertaken for the East Binnu area within Victoria location 8565, Western Australia. Groundwater monitoring bores were installed to assess the risk of dryland salinity developing if after clearance of native vegetation, the area is used to grow annual crops and pastures. The investigation confirmed that the risk of further salinity development in this location is extreme.

Successful Field Pea Harvesting, Glen Riethmuller, Ian Pritchard Sep 2003

Successful Field Pea Harvesting, Glen Riethmuller, Ian Pritchard

Bulletins 4000 -

Many thousands of hectares of field peas are harvested trouble free each year. Growers experience together with recent machinery innovations and modifications have solved the majority of harvesting difficulties. Optimum harvesting conditions are in a crop of uniform density on a level soil surface with the machine either working into or across the direction that the crop has been laid by the wind.

To make harvest easier the receival standard for moisture in pulses has been lifted to 14 per cent, which allows harvest to begin sooner when the crop is the range of 14 to 15 per cent moisture. …

Predicting The Effectiveness Of Farm Planning At The Byenup Hill Catchment Using A Groundwater Model, Gregory Paul Raper, L M. Guppy Sep 2003

Predicting The Effectiveness Of Farm Planning At The Byenup Hill Catchment Using A Groundwater Model, Gregory Paul Raper, L M. Guppy

Resource management technical reports

A catchment model was constructed for the Byenup Hill catchment based on detailed hydrogeological mapping, information on land mapping units and land use collected from landholders. The aim of this work was to assess the likely impact of proposed land management changes to soil salinisation and recharge in the Byenup Hill Catchment.


East Mortlock : Catchment Appraisal 2002, Don Cummins Jul 2003

East Mortlock : Catchment Appraisal 2002, Don Cummins

Resource management technical reports

This report describes the soils, hydrology, natural vegetation and farming systems of the East Mortlock catchment and provides information on the threats to agriculture, infrastructure and natural resources caused by land degradation. East Mortlock covers over 800,000 hectares in the central wheatbelt. Rapid Catchment Appraisal aims to document salinity risk and management options by addressing all threats to the natural resource base, rather than isolating salinity as a separate issue.


Zone Management In Precision Agriculture By Matching Fertiliser Input To Crop Demand, Daya Patabendige, Mike Wong, Bill Bowden Jun 2003

Zone Management In Precision Agriculture By Matching Fertiliser Input To Crop Demand, Daya Patabendige, Mike Wong, Bill Bowden

Bulletins 4000 -

Growers in Western Australia who have been yield mapping since the mid 1990s have come to realise that grain yield varies across different zones of their paddocks in any given year, as well as between years depending on the seasonal conditions and crop type. This within paddock variation can be as much as tenfold. Higher yielding areas can be due to better growing conditions (which increases the demand for nutrients) and/or better nutrient supply (which reduces the need for some fertiliser inputs). Hence, it is essential to determine the cause of the variation before optimum fertilising strategies can be developed.


Assessing Storage Reliability Of Farm Dams, D Farmer, N Coles May 2003

Assessing Storage Reliability Of Farm Dams, D Farmer, N Coles

Resource management technical reports

This report provides information on a method to estimate the volume of water in a farm dam and to determine how long this water will last. During periods of low rainfall, dams with farmland catchments receive limited run-off. Alternative water sources or management strategies need to be considered before the water runs out. The methods provided in this report are intended to provide to the landholder an indication of water supply over short periods only (i.e. in the order of 4-20 weeks).

Managing Blackleg : A Grower's Guide To Minimising Risk From Blackleg Disease Of Canola In Western Australia, Department Of Agriculture And Food, Western Australia Jan 2003

Managing Blackleg : A Grower's Guide To Minimising Risk From Blackleg Disease Of Canola In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Blackleg is spread primarily by wind, with the heaviest spore fall out normally occurring within 500 metres of any canola residue. Each year canola residue continues to produce blackleg spores at a diminishing rate until the stubble has completely broken down (see Diagram 2). In WA this breakdown could take up to 4 years, and so the recommendations are for long rotations.

The blackleg fungus can attack all the aerial parts of the plant. While leaf infection is the most obvious symptom, high levels of leaf infections do not necessarily indicate that major losses will occur from blackleg. It is …


The Effect Of Recreational Fishing On Targeted Fishes And Trophic Structure, In A Coral Reef Marine Park, Mark B. Westera Jan 2003

The Effect Of Recreational Fishing On Targeted Fishes And Trophic Structure, In A Coral Reef Marine Park, Mark B. Westera

Theses: Doctorates and Masters

Recreational line fishing is highly targeted at predatory fishes, making them vulnerable to overfishing. These same fishes play a role in trophic structure by regulating prey species. Despite increasing numbers of fishers, few studies have investigated the potential effects of recreational fishing on fish populations and subsequent trophic effects. This project investigated whether there were differences in fishes and benthos between unfished and recreationally fished areas, and whether the removal of targeted fishes influenced trophic structure. The study was conducted at the Ningaloo Marine Park, Western Australia, which had Sanctuary (no-take) and Recreation {recreationally fished) Zones. Data were collected from …
