Images 2.1 : An Integrated Model Of An Arid Grazing System, Z G. Yan, K M. Wang

Resource management technical reports

The name IMAGES stands for An Integrated Model of an Arid Grazing Ecological System. The model was initiated by Dr R. Hacker in 1987-8 as an activity to (1) evaluate alternative management strategies and (2) identify key ecological processes and research priorities in shrub rangelands of Western Australia. Version 1 of the model was published in Agriculture Systems in 1991 (Hacker et al. 1991) and here after will be referred to as IMAGES 1. IMAGES 1 is a vegetation model, capable of predicting the prob ility of recruitment and mortality of the desirable species in a given vegetation type under …

Assessment Of The Suitability For Agriculture Of The North-West Packsaddle Area Kununurra, N Schoknecht

Resource management technical reports

A brief assessment of the suitablility for agriculture of about 260 ha in the North-west Packsaddle area was conducted in early September 1993. Nine map units based on soil and landform were identified, and their suitability for broadscale flood irrigated agriculture and spray or trickle irrigated horticulture assessed. The map units are based on field observations and extrapolation from existing surveys. The map was prepared at a scale of 1:20,000 and is only accurate at that scale.

Processing Results Of Western Australian Wool, John Stanton A/Prof, Lindy Coss, Peter Metcalf

Resource management technical reports

Despite a perception by some that Western Australian wool 'processes poorly', this study found that the consignments processed:

1. into longer tops suited for worsted weaving

2. into longer than predicted tops

3. with the same consistency as other Australian consignments

Remnant Vegetation Inventory On The Southern Agricultural Areas Of Western Australia., G R. Beeston, G Mlodowski, A Sanders, D True

Resource management technical reports

Remnant vegetation mapping and its incorporation into a Geographical Information System (GIS) data base is the first stage in an overall documentation and promotion of conservation of remnant vegetation in Western Australia. The primary objective of this project being to determine the amount, distribution and regional location of native vegetation remaining on private land in the agricultural area of south-west Western Australia.

A Review Of Four On-Farm Water Supply Demonstration Farms, M H M Casey, I A F Laing

Resource management technical reports

In March 1982, the Western Australian Government allocated $100,000 to the Department of Agriculture to demonstrate appropriate, reliable, on-farm conservation technology on four farms in the north-eastern wheatbelt. The Government grant was matched dollar for dollar with the farmers funds with a maximum of $25,000 grant to any one farm. The demonstrations used existing techniques, such as dams and roaded catchments, to establish permanent drought-proof water supplies.

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.

No-Tillage Seeders And Their Adoption In North America With Relevance To Western Australia, J K. Bligh

Resource management technical reports

The adoption of no-tillage seeders appears generally to be at a similar stage in North America as in Western Australia. One notable difference is the communication provided by several no-tillage farmers organisations, such as the Manitoba-North Dakota Zero Tillage Farmers Association. Since almost all development of no-tillage systems has been carried out by farmers, such associations have proven invaluable in directly providing communication with their peers.

The Concept Of Prime Agricultural Land: A Western Australian Perspective, Vivian T. Read

Resource management technical reports

In the past, resource planning by Government authorities in Western Australia has been concentrated in urban areas. The rural areas were referred to as non-urban and planning outside of country townsites was confined to special rural zones. These zones were determined by the State authority (Town Planning Department) and were intended to limit the extent of farm fragmentation so as to control servicing costs and possible conflict.

The new State Planning Commission is expected soon to introduce the requirement of rural planning strategies for Local Government Areas where demand for land subdivision is high. The strategies will be based on …

Direct Seeding Trees On Farmland In The Western Australian Wheatbelt, J P. Piggott, P H. Brown, M M. Williams

Resource management technical reports

Field and nursery experiments were conducted to determine suitable species, weed control methods, sowing times and seeding techniques. Sowing time was the most significant variable evident in the field experiments. Trees sown in the winter months of June and July out-performed later sowing times. Early sowing of trees in areas of low seasonal rainfall appears to offer considerable advantages for successful establishment over late sowing.

Drains : A Method Of Financially Assessing Drains Used To Mitigate Waterlogging In South-Western Australia, John S. Salerian, D J. Mcfarlane

Resource management technical reports

Seepage interceptor drains are often effective in mitigating waterlogging in duplex (sand over clay) soils on hill slopes in the sout-west. Spoon and W drains are sometimes effective in removing excess surface waters form clay flats.

This report outlines a method to determine the long-term (1 to 20 years) cost-effectiveness of installing drains to mitigate waterlogging for each individual situation.

Camballin Irrigation Area : A Summary Of Cropping And Pasture Studies 1958-1970, Phongsak Yuhun

Resource management technical reports

The Camballin Irrigation Area was the first large scale rice growing area in Western Australia. It was hoped Camballin would develop into a highly productive irrigation area. The Department of Agriculture was directly involved in the area between 1958 and 1970. The report summarizes the research carried out during the period which paralleled the commercial operation. The trials were designed to solve the specific cropping problems encountered over the period.

Agricultural Water Quality Criteria : Irrigation Aspects., P R. George

Resource management technical reports

Water quality criteria for irrigation are imprecise. The final result of quality evaluation depends on plant, soil and climatic variables all of which can be inter-dependent. A range of management strategies of varying complexity are available to mitigate the effects of poor quality water. The heavy winter rainfall in the south-west of Western Australia affects the applicability of published salinity criteria most of which have been developed in arid and semi-arid environments with little effective rainfall.

The Problems And Prospects Of The Kimberley Pastoral Industry, R B. Hacker

Resource management technical reports

The pastoral industry in the Kimberley region began in the early 1880s withthe introduction of cattle overlanded from Queensland and New South Wales into the East Kimberley and with the almost simultaneous introduction, by sea, ofboth sheep and cattle into the Fitzroy Valley.Occupation of the more accessible areas was gradually achieved by theprogressive extension of these two arms of settlement which ultimately metaround the present location of Fitzroy Crossing. Extensive development of themore rugged areas of the North Kimberley came later with the construction ofreasonable access roads to the few isolated stations which had been initiallyestablished in this area.

Report suggests that the area of land suitable for Townsville Stylo in the North Kimberley above the 750 mm rainfall isohyet is about 1.25 million hectares. The regions in which land suitable for Stylosanthes can be found are shown. A brief description of the suitability of the land systems of the region for Stylosanthes is given.

Agricultural Development In The North Kimberley : Terms, Conditions And Farm Size Recommendations, D G. Wilcox, J Ripley, R F. Johnson

Resource management technical reports

There are approximately 1,250,000 hectares of land in this area of Kimberley which may be sown to pastures such as Townsville Stylo, other Stylosanthes species or to other introduced pastures. The report recommends that grazing properties comprising 10,000 ha. of land capable of growing improved pastures, together with 60,000 ha. of native pasture land, should be established in the area. The economic size of the farm unit is 5,300 adult cattle equivalents.

A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon

Resource management technical reports

Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.
