Minimal Soil Disturbance Sowing In New South Wales And Its Relevance To Reducing Water Erosion In Western Australia, K J. Bligh
Resource management technical reports
During a study tour in New South Wales both inexpensive modifications to existing seeders and state of the art new mechanisms were investigated. Narrow-winged points can readily be fitted to existing tined seeders to immediately reduce water erosion in Western Australia. Press wheels may improve crop establishment, particularly with early sowing in this predominantly winter-rainfall region.

Water Erosion On Vegetable Growing Land In South Western Australia, D J. Mcfarlane, N D. Delroy, H V. Gratte, J P. Middlemas, A M E Van Vreeswyk, I Mckissock
Resource management technical reports
The most serious erosion was found to be occurring in the Donnybrook area due to a combination of erosive winter rainfall, steep slopes and erodible soils. The most serious erosion was found to occur when storm runoff entered the vegetable plots from above, providing a transporting medium for the cultivated soil. A predictive model of erosion showed that soil texture, furrow slope, plot length, rainfall erosivity and canopy cover were significant factors affecting soil loss.
The Relationship Between The Concentration Of Total Soluble Salts And Osmotic Potential In Soil, Ground And Surface Waters For Several Regions Of Western Australia, H Borg
Resource management technical reports
In Western Australia salinity data are commonly reported in milligrams of total soluble salts per litre of solution. Laws from solution chemistry and data on the soluble salt composition for various regions of the State were combined to derive a relationship between total soluble salt concentration (C) and osmotic potential (WO) for each region. For the south-west of Western Australia, which contains the most productive agricultural areas in the Sate, this relationship is WO = 0.075 C.
