Measuring Soil Salinity, Department Of Primary Industries And Regional Development, Western Australia
Measuring Soil Salinity, Department Of Primary Industries And Regional Development, Western Australia
Natural resources factsheets
To make sound decisions on managing saline sites, you need to know the source of salt, how salinisation is occurring, the landscape context, and most importantly, the actual salt concentration of the soil.
The most common 'measures' of salt concentration are actually estimates based on electrical conductivity of a soil and water solution. Soil salt content can be measured in a laboratory by measuring the total dissolved solids in a sample. In the field, salt concentration can also be estimated using electromagnetic induction-based soil sensors.
Sheep Worm Control In Wa, Department Of Primary Industries And Regional Development, Western Australia
Sheep Worm Control In Wa, Department Of Primary Industries And Regional Development, Western Australia
Animal production and livestock factsheets
Effective, sustainable control of sheep worms involves a combination of planned stock and farm management, monitoring worm burdens using faecal worm egg counts (WEC), strategic timing of drenches and the genetic selection of worm resistant sheep.
Levels of drench resistance of sheep worms in WA are some of the highest in the world and without resistance management action at individual farm level, it will continue to worsen and spread.
Although effective drench options are generally available, many sheep owners are unaware that resistance has reduced the effectiveness of worm control programs, and this can affect profitable sheep production.
Early Weaning Of Lambs In A Poor Season, Department Of Primary Industries And Regional Development, Western Australia
Early Weaning Of Lambs In A Poor Season, Department Of Primary Industries And Regional Development, Western Australia
Animal production and livestock factsheets
The feed requirements of a ewe with a lamb at foot are higher than if the ewe and lambs are fed separately. In a difficult season with short feed supplies, it is better to early-wean lambs from their mothers to lower feed costs and ensure that the ewes regain condition before joining. This issue becomes even more important as the costs of feeds increase.
Ewe's milk provides the main source of nutrition for lambs until about eight weeks of age. Lambs will sample pasture from about two weeks after birth but by eight weeks of age pasture overtakes milk as …
Sheep Lice Spread And Detection, Department Of Primary Industries And Regional Development, Western Australia
Sheep Lice Spread And Detection, Department Of Primary Industries And Regional Development, Western Australia
Animal production and livestock factsheets
The most common lice affecting sheep are body lice (Bovicola ovis).
Knowledge of the lice life cycle and relevant features of their biology assist in our understanding of how lice survive and spread.
Better understanding and ability to find and monitor lice populations will improve sheep farmer decision making around eradicating lice.
Knowledge of when an infestation may have occurred, or alternatively that lice was not eradicated at the last shearing, is important information that will assist future treatment decisions.

Wind Erosion Control After Fire In Western Australia, Department Of Primary Industries And Regional Development, Western Australia
Natural resources factsheets
First steps after a fire
Act to limit further erosion:
• Remove livestock and keep them off burnt paddocks: they can be put into a confinement feeding area, an unburnt paddock or agisted.
• Minimise vehicle traffic on burnt areas
• Protect highly susceptible and valuable areas, such as house, garden, sheds, yards, gateways and laneways with binding spray, clay, gravel, old hay, or straw to give a full cover. A dust-free living and working environment is particularly important after a fire.
Leave burnt residue on roadsides, revegetation and bush areas to decrease the risk of wind erosion.

Natural revegetation and no grazing are only recommended for sites that are too saline, waterlogged and/or inundated for other treatments to succeed in the south-west of Western Australia. It is also the preferred option for the lowest possible cost.
Saltland Pastures In Western Australia, Department Of Primary Industries And Regional Development, Western Australia
Saltland Pastures In Western Australia, Department Of Primary Industries And Regional Development, Western Australia
Natural resources factsheets
Saltland pastures are associations of salt and waterlogging-tolerant plants that produce fodder for grazing animals from saline and waterlogged soils. Saltland pastures can improve production from saltland sites, reduce salt movement from the site, and improve soil structure.
The Department of Primary Industries and Regional Development recommends that saltland management is part of a whole-farm, and preferably whole-catchment, plan.
Lupin Root Diseases - Diagnosis And Management, Department Of Primary Industries And Regional Development, Western Australia
Lupin Root Diseases - Diagnosis And Management, Department Of Primary Industries And Regional Development, Western Australia
Grains and other field crops factsheets
Root, hypocotyl and stem base diseases can be significant problems in lupin crops, reducing stand density, plant vigour and yield. Root disease is present in nearly all narrow leafed lupin (Lupinus angustifolius) paddocks but in the majority of paddocks has only a small impact on crop development. However, in paddocks where high levels of root rot occurs, plant establishment, seedling vigour and crop yield can be significantly affected.
When a root disease is present in a crop very little can be done to manage it in that cropping season. It is therefore vital that the cause is correctly identified to …
Time Of Lambing, Department Of Primary Industries And Regional Development, Western Australia
Time Of Lambing, Department Of Primary Industries And Regional Development, Western Australia
Animal production and livestock factsheets
Choosing the best time of lambing, and matching paddock feed availability to ewe and weaner needs is important for both productivity and profitability. The ewes' natural breeding season will also affect reproductive rates. The ewe flock is the key flock on the farm, so it is important to set up a system that matches their needs with the feedbase. A ewe’s condition will vary over the season depending on the feed available and her needs. A ewe’s energy needs will double in late pregnancy and triple in lactation. Having enough feed to meet her changing needs is important for production …

Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia
Rabbit Control: Warren And Harbourage Destruction, Department Of Primary Industries And Regional Development, Western Australia
Biosecurity factsheets
If correctly and appropriately undertaken, the destruction of rabbit warrens, or modification of the habitat so it becomes less favourable to rabbits, can be an important and effective part of reducing the impacts of rabbits.
Destruction of warrens can improve the overall effectiveness of rabbit control programs, even though many rabbits live and shelter above-ground under bushes, and in scrub). If undertaken properly, the ripping of rabbit warrens can often provide a relatively permanent and long-term benefit. Similarly, removing or modifying other forms of rabbit-harbourage (for example, removing rock piles) can help, particularly in semi-urban areas or on smallholdings.
