Technical Bulletins
The Ivanhoe Plain was divided into two geomorphic provinces. The principal difference between the provinces is the time during which pedogenesis occurred. The crcking clay soils of the northern province are generally more highly leached than their younger counterparts in the southern province. Sixteen land units are identified as distinct from soil units. These units give cognizance to vegetation and topographical features as well as soils.

Trial 90EC29
Effect of depth and degree of soil disturbance on root and shoot growth of wheat on wind erosion prone sandy soil.
Location: East Chapman Research Station.
The long-term fertility and stability of the yellow, grey and white sands which make up 60% of the northern wheatbelt soils can only be safeguarded through strict adherence to conservation cropping practices: notably, direct drilling of both cereal and lupin crops. Work by R. Jarvis has shown a 10 - 15% yield advantage due to cultivation of sandplain soils, and data suggest that it is cultivation depth (degree of soil loosening) rather …

Level Banks Used To Decrease Waterlogging Can Increase Salinity, Don Mcfarlane, Richard Engel, Arjen Ryder, Maurice Eales
Level Banks Used To Decrease Waterlogging Can Increase Salinity, Don Mcfarlane, Richard Engel, Arjen Ryder, Maurice Eales
Journal of the Department of Agriculture, Western Australia, Series 4
Some farmers have used level W1SALTS banks to control surface zvaters above areas affected by ivaterlogging and salinity. Because the amount of waterlogging has been reduced, crop yields have increased downslope of some banks. However, the banks divert fresh surface water into deeper salty groundwater and, in the long term, worsen salinity. This article details an investigation of the effect of level WIS ALTS banks on saline groundwaters and discusses alternative methods of preventing the waterlogging of saline areas.
