Arkansas Rice Research Studies 1991, B. R. Wells
Arkansas Rice Research Studies 1991, B. R. Wells
Arkansas Agricultural Experiment Station Research Series
The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1991, Arkansas Agricultural Experiment Station Research Series 421. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

Arkansas Soil Fertility Studies 1991, Wayne E. Sabbe
Arkansas Agricultural Experiment Station Research Series
Contained within this publication are progress reports on the specific aspects of the soil fertility program at the University of Arkansas in 1991. In most instances, the reports are not final reports, but they may contain data from several years. Further details on each report can be obtained from the respective project leaders.

Stubble Retention For Control Of Wind Erosion, Dan Carter, Paul Findlater, Steve Porritt
Stubble Retention For Control Of Wind Erosion, Dan Carter, Paul Findlater, Steve Porritt
Journal of the Department of Agriculture, Western Australia, Series 4
The surest way to control wind erosion in continuous cropping systems is to retain stubble. Over the past ten years, Western Australian research has focused on the amounts of stubble needed to prevent that erosion.
Stubble : Friend And Foe, Department Of Agriculture And Food, Western Australia
Stubble : Friend And Foe, Department Of Agriculture And Food, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Several articles in this issue of the Journal of Agriculture discuss some of the important issues of stubble management. The articles are condensed from some of the papers presented at a stubble workshop at Geraldton in 1991.

Results Of Stubble Research In Western Australia, Michael Perry, Ron Jarvis, Mel Mason, David Tennant
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
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 …

Wider Spaced Rows For Lupins, Ron Jarvis
Journal of the Department of Agriculture, Western Australia, Series 4
In this farm scale trial at Wongan Hills, a lined combine was used to seed lupins into rows spaced 380 mm apart in wheat stubble.
The Pros & Cons Of Retaining Stubble, Department Of Agriculture And Food, Western Australia
The Pros & Cons Of Retaining Stubble, Department Of Agriculture And Food, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Few farmers in Western Australia today would question the desirability of retaining crop stubble. The problem usually is how to manage stubble so that it does not interfere with other parts of the farming system
The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker
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.
