Declared Plant Control Handbook Recommendations For The Control Of Declared Plants In Western Australia, John R. Peirce, Rachael A. Pratt Jan 2002

Declared Plant Control Handbook Recommendations For The Control Of Declared Plants In Western Australia, John R. Peirce, Rachael A. Pratt

Biosecurity published reports

Sixth Edition.

Reviewed October 2005.

Plants may be "declared" by the Agriculture Protection Board under the Agriculture and Related Resources Protection Act 1976.If a plant is declared, all landholders are obliged to control that plant on their properties. Declarations specifies a category, or categories, for each plant according to the control strategies or objectives which the Agriculture Protection Board believes are appropriate in a particular place.

Among the factors considered in categorising declared plants are:

* the impact of the plant on individuals, agricultural production and the community in general,

* whether it is already established in the area, and …


Fertigation Of Vegetables In Western Australia, J Burt Jan 2002

Fertigation Of Vegetables In Western Australia, J Burt

Bulletins 4000 -

Fertigation is the technique of using soluble fertilisers to supply essential nutrients to vegetables through sprinkler or trickle irrigation systems, or by means of a boom spray. It is ideally suited to most horticultural areas in Western Australia, especially the sandy soils of the Swan Coastal Plain that have a poor capacity to retain nutrients.

Before and after planting, nutrients are often applied to vegetables on soils of the Swan Coastal Plain by applications of poultry manure* or solid fertilisers. After planting, fertigation is a safe and effective method of applying top-dressings of nutrients to crops, especially after the rows …

Review Of Soil Conservation Legislation : Carnarvon Horticultural Area, Jean-Pierre Clement Jan 2002

Review Of Soil Conservation Legislation : Carnarvon Horticultural Area, Jean-Pierre Clement

Agriculture reports

Lower Gascoyne Management Strategy The Carnarvon horticultural area has suffered considerable erosion damage following flooding of the Gascoyne River. Factors contributing to the erosion include a move to greater vegetable production, the carrying out of unauthorised earthworks and general confusion about the laws that apply to land management and erosion control. With this context, the purpose of this report is: • to clarify the laws applying to erosion control in the Carnarvon horticultural area; • to identify the public authorities with management responsibility for erosion control; and • to suggest a model by which erosion controls and management responsibilities can …

Potential Runoff Accumulation In Wheatbelt Towns Of Western Australia, Mahtab Ali, Travis Cattlin, Neil Coles, Sharam Sharafi

Resource management technical reports

Describes an analysis of flood runoff volumes from 16 small, gauged catchments in the agricultural areas of south western Australia. It also describes methods for estimating flood runoff volumes from ungauged catchments. The independent variables found to be statistically significant in explaining the variability in flood runoff volumes from the gauged catchments were catchment area, mean annual rainfall and the percentage of the catchment that was cleared. No soil factor was found to be significant.

Fisheries Research Report No. 130 - Environmental Requirements And Tolerances Of Rainbow Trout (Oncorhynchus Mykiss) And Brown Trout (Salmo Trutta) With Special Reference To Western Australia: A Review, Brett W. Molony Nov 2001

Fisheries Research Report No. 130 - Environmental Requirements And Tolerances Of Rainbow Trout (Oncorhynchus Mykiss) And Brown Trout (Salmo Trutta) With Special Reference To Western Australia: A Review, Brett W. Molony

Fisheries Research Reports

Both Oncorhynchus mykiss (rainbow trout) and Salmo trutta (brown trout) have a long history of translocation and culture and a wide knowledge base exists. O.mykiss is being considered as a candidate for inland aquaculture in the salinity affected areas of southern Western Australia and this review aims, in part, at providing relevant information to those considering a trout-framing venture in Western Australia. Both species of trout can survive a wide range of environmental conditions, including temperature, salinity, pH, dissolved oxygen and ammonia, with O.mykiss having a higher temperature tolerance than S.trutta. However, within the ranges of environmental conditions, each species …
