Planning To Grow Vegetables Commercially, John Burt, Peter Gartrell Jan 1998

Planning To Grow Vegetables Commercially, John Burt, Peter Gartrell

Bulletins 4000 -

This Bulletin was developed by Department of Agriculture in recognition of the increasing complexity and competitiveness in establishing a commercial vegetable enterprise. The information in this Bulletin will provide you with a useful guide to assess your likelihood of succeeding in vegetable production.

Vegetable production is not an easy lifestyle. It is a highly competitive environment with the industry consisting of growers with big investments and years of experience and knowledge. Horticultural farms require a large amount of capital and time and are increasingly expanding and becoming more specialised.

If you are serious about growing vegetables, work through this Bulletin …

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 70 ha catchment located about 15 km north of Williams, Western Australia. The catchment receives about 545 mm annual rainfall and 1870 mm annual evaporation. Development of salinity is characterised by passive discharge upslope from a dolerite dyke. Because recharge exceeds the discharge capacity of current seeps, there is potential for new seeps to develop in the mid to lower slopes.

Resource management technical reports

The south-western Woolbelt receives annual rainfall between 500-700 mm with long dry summers and cool wet winters. The dominant land use is grazing of Merino sheep for wool productiion, with smaller areas (5-15%) of cropping. All of the catchments selected were affected by salinity, but the extent and severity varied. In all catchments the location of the major expression of salinity was the valley floor.

1080 Operational Procedures Manual - Second Edition, Agriculture Western Australia Jan 1998

1080 Operational Procedures Manual - Second Edition, Agriculture Western Australia

Biosecurity published reports

Sodium fluoroacetate (1080) is an extremely toxic substance which can be a danger to humans if handled incorrectly. At the same time 1080 is the most effective and efficient poison for the control of Western Australia's main vertebrate pest species including rabbits, wild dogs and foxes. One of the main reasons for its usefulness in Western Australia is that many native animals have a high tolerance to it and so may not be affected by baiting.

Industry Resource Protection Program (IRPP) This program, part of Agriculture Western Australia, supports feral animal control carried out by its staff and community groups. …

Management Options For Pilbara Demersal Line Fishing, Gaye Looby Nov 1997

Management Options For Pilbara Demersal Line Fishing, Gaye Looby

Fisheries Management Papers

Fisheries Western Australia licensing arrangements allow all vessels with an unrestircted fishing boat licence ('wetline licence') to take scalefish throughout the State. These arrangements have led to a high level of excess capacity in the licensed 'wetline' fishing fleet to exploit the scalefish resources. The declaration of the Kimberley Interim Line Fishery and forthcoming declaration the Northern Demersal Scalefish Fishery have resolved this problem for the Kimberley waters. However, the high level of excss capacity in the 'wetline' fleet to exploit the waters of the Pilbara remains a problem Preview access and develop a management plan for the Pilbara demersal …


Salinity And Hydrology Of The Mills Lake Catchment, R Ferdowsian, A T. Ryder Nov 1997

Salinity And Hydrology Of The Mills Lake Catchment, R Ferdowsian, A T. Ryder

Resource management technical reports

The Mills Lake Catchment is located north of the Ongerup-Jerramungup Road, 35 km west of Jerramungup and 10 km north-east of Ongerup. It covers about 23,800 ha of agricultural land that is more than 90% cleared and predominantly cropped. The average annual rainfall of the catchment is about 370 mm. Many low-lying parts of the study area have become salt-affected during recent years. The extent of soil salinity is growing rapidly and it is feared that, without any treatment, more land will become salt-affected.

The Salinity And Hydrology Of Cranbrook, R Ferdowsian, A T. Ryder Oct 1997

The Salinity And Hydrology Of Cranbrook, R Ferdowsian, A T. Ryder

Resource management technical reports

The study area covers the Cranbrook townsite and two catchments that affect it. The Cranbrook Town is located 85 km north-north-west of Albany and it has a population of 320 people (1190 in the Shire; ABS Census 1991).

Cranbrook is experiencing salinity problems. Saline groundwater levels are close to the soil surface and cause deterioration of buildings, roads, infrastructure, death of trees and scalding of land including the sporting ground.

The objective of this study was to define the present salinity status of the Cranbrook Town and develop management strategies to overcome or reduce the severity of salinity.

Phosphorus And Nitrate Loss From Horticulture On The Swan Coastal Plain, Neil Clifton Lantzke Aug 1997

Phosphorus And Nitrate Loss From Horticulture On The Swan Coastal Plain, Neil Clifton Lantzke

Agriculture reports

(En) The extent of nutrient loss from nine horticultural properties located on the sandy soils of the Swan Coastal Plain was examined. On three of the properties phosphorus (P) loss was measured by monitoring nutrient loads in shallow drains. On the other six properties networks of monitoring bores were installed and both P and nitrate nitrogen (NO3-N) concentrations were monitored. All of the properties except one were located on the low phosphate fixing Bassendean sands. The level of nutrient loss was depend l production areas. High to very high N03-N concentrations were found in the shallow groundwater beneath the production …

Bulletin 4328 - Soil Testing For Vegetable Production On The Coastal Plain, Ian Mcpharlin, Murray Hegney May 1997

Bulletin 4328 - Soil Testing For Vegetable Production On The Coastal Plain, Ian Mcpharlin, Murray Hegney

Bulletins 4000 -

Vegetable growers need to use fertiliser efficiently. Under-fertilising can reduce yield, which results in economic losses. Over-fertilising can reduce yield and contribute to nitrogen and phosphorus pollution of ground and surface waters. Concerns have been expressed that fertilisers applied to horticultural crops contribute to the phosphorus pollution of the rivers and estuaries of the west and south coast of Western Australia.

Soil testing is a technique that can be used by growers to make better fertiliser decisions. When soil tests show high levels of nutrients, growers can reduce fertiliser application for the current crop. This should enable growers to maintain …

Native Vegetation On Farms Survey 1996 : A Survey Of Farmers Attitudes To Native Vegetation And Landcare In The Wheatbelt Of Western Australia, Suzanne Jenkins

Resource management technical reports

The Native Vegetation on Farms survey 1996 was performed to assess the attitudes of farmers to a number of issues related to existing native vegetation on farmland, the replanting of vegetation on farms and land degradation. Research has shown that it is important for a proportion of all farmland to have some native vegetation for ecological stability, to regulate hydrological processes and for long-term sustainability of farm production.

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow Mar 1997

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow

Bulletins 4000 -

This Bulletin discusses the benefits that furrow sowing brings to crop growth and production on water repellent sand, based on research and farm observations in Western Australian. By understanding the benefits and risks of several key processes, producers can better evaluate the potential role of furrow sowing in combating water repellency. This is true whether one is using direct drilling, no-till (narrow points or discs) or zero till (single, double or triple disc openers) methods.
