Roaded Catchments In Wa, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Roaded catchments are earthwork structures designed to increase the amount of run-off from the catchment above a receiving farm dam.

Roaded catchments are lined with clay and compacted to make a smooth surface that reduces infiltration and increases run-off. Roaded catchments should discharge into a silt trap and then into a dam (excavated earth tank). This combined structure should be fenced to exclude livestock.

The Department of Primary Industries and Regional Development recommends that roaded catchments are part of an integrated water and salinity management program.

Blackleg And Its Management In Canola, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Blackleg, caused by the fungus Leptosphaeria maculans, is the most common and serious disease of canola in Western Australia (WA). Blackleg can cause significant damage by infecting the cotyledons or first leaves early in the season, leading ultimately to crown lesions or cankers later in the season.

Changes in variety choice, crop rotation, earlier sowing times, and stubble retention have extended the risk of blackleg disease. Because of early emergence, later stages of crop growth are more likely to be exposed and infection can occur on all parts of the plant above ground, including canola flowers, stems, and branches (this …

Animal production and livestock published reports

Western Australia’s (WA) agricultural land use system features extensive pasture land vital for grazing sheep and cattle. Most pastures in the south west of Western Australia consist of annual species that grow during the cool, wet winters of the Mediterranean climate and senesce in the warm to hot, dry summers. Understanding the spatial distribution of pasture areas within the context of mixed farming is essential for developing effective land management strategies to enhance livestock production and profitability through balanced pasture supply and demand.

This report focuses on reconciling pasture area data for the south-west of Western Australia’s agricultural zone across …

Brome Grass And Its Management In Crops, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Brome grass (Bromus spp.) is one of the most competitive grass weeds in wheat. Over the last 10 years, brome grass has increased in importance to a greater extent than any other weed species in Australia.

Recent changes in crop production systems, increased conservation tillage, a lack of available selective herbicides, and a decline in system diversity have seen an increase in the importance of this weed in Western Australia (WA).

Seed is the main source of brome grass infestation and, as few seeds remain dormant, the most important aspect of management is to reduce its seed bank.

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr, Meredith M. Guthrie

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.
