Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason
Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason
Bulletins 4000 -
Because fertiliser prices are high, it is important to understand what affects the response to fertilisers by crops.
Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, you need some understanding of how these factors work.
Greatest responses to nitrogen fertilisers can be expected in areas with a relatively long growing season. In such areas light soils with a low nitrogen status give the …
Delaying The Development Of Herbicide Resistant Ryegrass By Using Alternative Weed Control Strategies, A. J. Diggle, G. S. Gill, J. E. Holmes
Delaying The Development Of Herbicide Resistant Ryegrass By Using Alternative Weed Control Strategies, A. J. Diggle, G. S. Gill, J. E. Holmes
Biosecurity published reports
Alternative strategies to control ryegrass in wheat lupin rotations are worth approximately 15 dollars per hectare for each 50% reduction achieved in plant or seed numbers. This figure has been calculated for circumstances similar to those found at Wongan Hills, and it holds in all cases where ryegrass is still under control using standard herbicides.
Farmers should adopt any ryegrass strategy in addition to that normally practised, so long as the cost to control ratio is less than $15/ha/50% kill. This applies even where good control is being achieved using grass selective herbicides, regardless of the number of previous applications …

Bulletin 4278 - How To Use Wide Furrow Sowing For Improved Crop Production On Water Repellent Sand, Paul Blackwell, Grant Morrow, Tony Webster
Bulletins 4000 -
Wide furrow sowing is a method for successfully establishing crops of lupins or cereals on non-wetting sands, and improving crop establishment on non-repellent sands. The same principles can be used to assist establishment of fodder shrubs and long-term pasture (e.g. tagasaste and Rhodes grass).
Bluegum Timberbelts For Profitable Landcare, Peter Eckersley
Bluegum Timberbelts For Profitable Landcare, Peter Eckersley
Journal of the Department of Agriculture, Western Australia, Series 4
Revegetation with tasmanian bluegums in wide-spaced timberbelts appears to offer high returns, especially in areas where high winds cause crop and stock losses and where land can be saved from salinity and wwaterlogging.
In the South Coast and South-WestRegions, timberbelts will complement existing enterprises and so optimise overall land use. Graziers should be able to maintaine their stock numbers while creating an on-farm superannuation package.
The Department of Conservation and Land Management has been a major player in the development of bluegum timberbelts, but a few farmers are now adapting this concept to better suit their needs. Initial results are …

Miscellaneous Publication 42/93 - Development And Dissemination Of Design Methods For Rangeland Paddocks Which Maximise Animal Production And Minimise Land Degradation, Shane Cridland, Mark Stafford Smith
Animal production and livestock published reports
Surveys of rangeland resources in Western Australia to date have shown that 23% of the area surveyed is in poor range condition. Poor condition is characterised by the loss of perennial vegetation allowing wind and water erosion. Approximately another 37% is in only fair range condition (Curry and Hacker 1990).
The loss of range condition is partly due to uneven use of paddocks by sheep and cattle. The areas close to water and the preferred pasture types are often over-utilised, while areas well away from water and less preferred pasture types are under-utilised. The result is that rangeland in good, …

Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell
Journal of the Department of Agriculture, Western Australia, Series 4
The area sown to field peas in Western Australia's eastern wheatbelt has increased from 4000 ha in 1985 to about 35, 000 ha in 1992.
While field peas can be grown on soil types not suited to lupins, their stubble is highly fragile and prone to wind erosion, even at low grazing pressure. This is one reason why some farmers are hesitant to grow field peas.
Haroest losses of field peas can also be high; levels of JOO to 200 kg/ha of seed on the ground are not uncommon. For this reason farmers believe the stubbles should be grazed.

Journal of the Department of Agriculture, Western Australia, Series 4
Few farmers would question the desirability of retaining stubbles, both for control of erosion by wind and water, and to return organic matter to the soil. While the present debate is focused on the short term management of stubbles, longer term effects also need to be considered.
The Department of Agriculture has several long-running trials intended to measure long term effects.

Managing Brome Grass In The Wheat:Lupin Rotation, Aik Hock Cheam, Gurget Gil, Christine Zaicou
Journal of the Department of Agriculture, Western Australia, Series 4
Some farmers and scientists are questioning the sustainability of the cereal:lupin rotation in the Western Australian wheatbelt.
Being a 'tight' rotation, its continuation is constantly under threat by disease, especially lupin root rots caused by Pleiochaeta (the brown spot organism) and Rhizoctonia fungi. To control disease, some farmers have lengthened the rotation to three years, such as wheat:wheat:lupins or wheat:barley:lupins. The longer cereal phase also helps to stabilise soil against wind erosion. However, such rotations can lead to a rapid buildup of brome grass during the two consecutive years of cereals. The implications of these rotations on the severity of …

The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker
Journal of the Department of Agriculture, Western Australia, Series 4
Earthworms have a reputation as soil builders and renovators, particularly among 'organic' farmers and gardeners. They improve soil fertility through increased aeration, aggregation, water infiltration and release of nutrients from organic matter. However, the benefits of earthworms in the wheatbelt have been doubted for many years because of their poor survival in cultivated soils.
Since cropping began in the Western Auslmlian whealbelt over 1OO years ago, the physical condition of many soils has deteriorated. The primary causes of soil degradation were the European cultivation practices used by farmers and the trampling effect of introduced animals. in particular, sheep.

G91-1025 Two Crops In One Year: Doublecropping, Russell Moomaw, Gary Lesoing, Charles A. Francis
University of Nebraska-Lincoln Extension: Historical Materials
Choice of crops, weed control, and other cultural practices for successful doublecropping are discussed here. Multiple cropping refers to growing two crops on the same field during the same year. One method of multiple cropping is doublecropping, which is when one crop is grown after the first crop is harvested. Prime USA regions for doublecropping are the eastern cornbelt, and southeastern and south central states where relatively long growing seasons and abundant rainfall occur. By contrast, shorter growing seasons and less frequent rainfall limit the potential for doublecropping in Nebraska. Irrigation is essential for successful doublecropping in Nebraska. Without irrigation, …

Many urban Australians have little understanding of the problems of land degradation because it's an extremely slow process that doesn 't directly influence their day-to-day lives. Understandably, they would have trouble relating to sub-soil compaction, waterlogging, increased soil acidity and salinity. They also have trouble comprehending why fencing according to soil type is an important management tool for farmers, or what role contour banks, drainage systems, the addition of gypsum and planting trees have in reversing land degradation. But given that tree loss "has been at the core of almost every aspect of land degradation in Australia ", and that …
Tree Crops For Profit And Land Improvement, John Bartle
Tree Crops For Profit And Land Improvement, John Bartle
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.
Plant Growth And Survival In Saline, Waterlogged Soils, Ed Barrett-Lennard, Neil Davidson, Richard Galloway
Plant Growth And Survival In Saline, Waterlogged Soils, Ed Barrett-Lennard, Neil Davidson, Richard Galloway
Journal of the Department of Agriculture, Western Australia, Series 4
Waterlogged soils in Western Australia are often salt-affected. Recent research has shown that the interaction between waterlogging and salinity has a far greater adverse effect on plant groivth and survival than either of these two factors individually. The consequences of the combined effects of salt and waterlogging for most plant species are increased salt uptake, reduced growth, chlorosis (yellowing of leaves), defoliation, and death. Salt sensitive agricultural species (nonhalophytes) are more severely affected by this interaction than salt tolerant species (halophytes).

Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford
Journal of the Department of Agriculture, Western Australia, Series 4
Lack of oxygen is the major cause of limited plant growth in waterlogged soils. When soils become waterlogged less gas diffuses to and from the roots through the soil pores; there are changes in concentrations of mineral elements in soil solutions; and toxic products of roots and soil microorganisms begin to accumulate. These changes adversely affect germination, growth and development of plants.

Waterlogging is highly variable, both between years and within paddocks. This residts in uncertainty as to whether a paddock should be cropped in a particular year, and whether different management should be used on waterlogged areas within a paddock
A study has determined what are the most important causes of waterlogged soils.
The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard
The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard
Journal of the Department of Agriculture, Western Australia, Series 4
Harvest losses represent a significant reduction in lupin production and farm productivity.
Since 1984, the Department's Farm Machinery Research and Liaison Unit at the Dryland Research Institute has studied the lupin harvesting operation to improve its mechanical efficiency. An experimental and a prototype harvesting front were built and tested in the field. Guidlines for efficient lupin harvesting were produced, and commercial modifications developed.
Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater
Erosion Potential Of Phomopsis-Resistant Lupins, D J. Carter, Paul Findlater
Journal of the Department of Agriculture, Western Australia, Series 4
During lupin harvesting, up to 20 per cent of the grain remains on the ground. This non-harvested or pilt grain is a valuable feed for sheep during early summer because the pods, leaf and stem generally provide little nutrient in the stubnbles. In addition, the more efficient the weed control, the less valuable are the stubbles.
The disease lupinosis caused by Phomopsis leptostromiformis restricts the amount of grazing from the lupin stubbles, and hence the risk of wind-erosion of stubble paddocks.
However, the introduction of lupin varieties moderately resistant to Phomopsis and with reduced potential to cause lupinosis means that …
Frost Injury To Wheat, S P. Loss
Frost Injury To Wheat, S P. Loss
Journal of the Department of Agriculture, Western Australia, Series 4
Frost injury has not been a major concern to the Western Australian wheat industry despite causing spectacular but irregular crop losses on some farms.
The development of suitable herbicides, direct drilling technology and the adoption of early flowering varieties in the late 1970s and early 1980s led to wheat crops being sown and flowering earlier than previously. This resulted in an increase in the incidence of frost damage.
Research into frost indicates that most wheat producers face low to moderate risks of yield loss caused by frost. However, individual farms in particular years can suffer devestating widespread losses. Grost injury …
