Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell

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

The area sown to field peas in Western Australia's eastern wheatbelt has increased from 4000 ha in 1985 to about 35, 000 ha in 1992.

While field peas can be grown on soil types not suited to lupins, their stubble is highly fragile and prone to wind erosion, even at low grazing pressure. This is one reason why some farmers are hesitant to grow field peas.

Haroest losses of field peas can also be high; levels of JOO to 200 kg/ha of seed on the ground are not uncommon. For this reason farmers believe the stubbles should be grazed.

Honey Production In Western Australia, Rob Manning

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

the first ever survey of the potential production and value of apiary products from the south-west of Western Australia has shown beekeepers are collecting only 10 per cent of the potential honey crop.

The biggeest losses in honey production are caused by the enviroment, such as protracted drought, and extreme temperatures, heavy rain and cyclones during flowering. Fire, apiary sites leased but not used, and logging of forests also reduce the availability of apiary sites for honey production.

A Study Of The Benefits Of Reflection By Journal Writing In Mathematical Learning And Attitudes In The Primary School, Sally Edmonds

Theses : Honours

This descriptive study examines journal writing for the purpose of identifying aspects of children's mathematical reflective ability. It was hypothesised that encouragement to engage with the process of mathematics by reflective writing would reveal and assist learning, and give children a vehicle through which they could express their attitudes about the mathematics they were learning. The aim of this study was to find answers to the following question: How does the keeping of a mathematical journal reveal children's understandings of the mathematics they are learning? Other questions related to the study were: -What evidence is there from the journals about …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

Using Hypermedia To Improve The Dissemination And Accessibility Of Syllabus Documents With Particular Reference To Primary Mathematics, Alistair B. Campbell

Theses: Doctorates and Masters

The fundamental question that this study set out to investigate was: Can the advantages of hypermedia be extended to curriculum materials that are for the sole use of teachers? To consider this question, three areas needed to be investigated: hypermedia (the medium); teachers (the target) and curriculum documents (the content). Hypermedia has a long history dating back to Bush (1986) who in 1945 imagined his Memex system as building information trails between ideas. However, it was not until the mid 1980s that technology caught up with the theory and hypermedia came of age. The evaluation of hypermedia documents is still …

Post-Shearing Losses Of Sheep Following Cyclonic Rains, M. Holm Glass, R. Jacob

Animal production and livestock published reports

Sudden unpredicted rainfall during summer has caused high mortality rates in newly shorn sheep on at least two previous occasions. These occurred at Darkan, Western Australia, in 1982 (Buckman 1982) and at Kybylolite in the south-east of South Australia in 1960 (Geytenbeek 1982).

Geytenbeek (1982) reported an average mortality of 8.3%, which was highest for sheep within five days of shearing. The mortality declined for animals shorn more than seven days before the rain.

Buckman (1982) reported an average mortality of 27.9% which was highest within 12 days of shearing. The losses related directly to the amount of rain received. …

Influence Of Water Supply On Farm Productivity In The North-Eastern Wheatbelt, E J. Hauck

Resource management technical reports

In the area with reliable reticulated water supplies, average what yield, average wool production and average number of sheep per pastured hectare showed a positive correlation with annual rainfall in all but one year. By contrast, in the area served by on-farm water supplies only, average wheat yield and annual rainfall were strongly correlated, whereas average wool production and average number of sheep per pastured hectare showed a weaker correlation with annual rainfall. These correlations suggest tt on farms with a reliable water supply, livestock numbers have been adjusted annually to ensure optimum utilisation of available feed in all seasons.

Effects Of Waterlogging On Crop And Pasture Production In The Upper Great Southern, Western Australia, J F. Wallace, G A. Wheaton, D J. Mcfarlane

Technical Bulletins

Separate estimates of the effect of waterlogging on cereal yields were made using rainfall and crop yield statistics, and remote sensing. Both methods showed that waterlogging costs tens of millions of dollars each year in lost crop production in the Upper Great Southern Statistical Division. The costs will be over $100 m in wet years. Losses in pasture production are likely to be of a similar magnitude, but are harder to quantify.

The objective of the Remnant Vegetation Protection Scheme is to encourage land owners to fence and protect areas of remnant vegetation for the purposes of flora and fauna conservation, land conservation and aesthetics. The means by which land owners are encouraged to protect remnant vegetation is the provision of a grant equal to half the cost of labour and materials to erect a stock-proof fence around the vegetation concerned. The RVPS is jointly administered by the Departments of Conservation and Land Management (CALM) and Agriculture (DAWA), with the latter as the lead agency. CALM contributes substantially to the RVPS through …

Fodder Trees And Shrubs For High Rainfall Areas Of South Western Australia, Daya Patabendige, P R. Scott, Edward C. Lefroy

Resource management technical reports

In south Western Australia, the lack of good quality feed in late summer and autumn is a major constraint to livestock production. This feed gap is usually filled by costly supplementary hand feeding of grain or hay. The ability of some trees and shrubs to provide good quality forage during summer and autumn has generated interest for many years (Corbett, 1951; Everist, 1969; Snook, 1987;Oldham et al., 1991, Lefroy, 1991). The dual benefits of reducing the need for supplementary hand feeding and deferring the grazing of annual pastures until they are well established has recently led to the recognition of …

Land Reclamation In The North Stirling Land Conservation District, M F. Lewis, National Soil Conservation Program (Australia)

Resource management technical reports

Investigations were carried out to determine the interaction between the lakes and groundwater systems, the influence of bedrock structures on groundwater flow, and the regional flow characteristics in the basin. The hydrological investigations showed that water does flow from lakes to the groundwater system. However, the benefits from draining land have to be compared with the benefits of not adding water to the lakes. A basin water balance showed that most of the excess water resulting from reduced epotranspiration since clearing remains in the basin as increased groundwater storage. Only relatively small quantities of the extra water leave the basin …

Deep Drains : A Case Study And Discussion, Russell John Speed, John Andrew Simons

Resource management technical reports

Typically, deep, open drains are about 2 in deep and about 1 in wide at the base and dug with a backhoe or excavator. The movement of groundwater is controlled by two factors. One is the physical ability of the material to transmit fluid. Permeability is the measure used to describe the ability of a material to transmit fluid through pores and cracks. It depends largely upon porosity (the percentage of the total volume of thematerial that is pore space) and the degree of interconnectedness of the pore spaces. The other factor controlling groundwater flow is gradient. George (1985) found …

Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant

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

Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.

The Department of Agriculture has several long-running trials intended to measure long term effects.
