Soil And Lithostratigraphy Below The Loveland/Sicily Island Silt, Crowley's Ridge, Arkansas, Donna Porter, Sam Bishop

Journal of the Arkansas Academy of Science

Two stratigraphic units between the Loveland/Sicily Island Silt and the Pliocene sand and gravel on Crowley's Ridge were analyzed to determine their origin and assess the degree of pedogenic development. The Crowley's Ridge Loess, the upper unit, was up to 2.6 m thick, was not laterally continuous, and contained a well developed paleosol. The lower unit was a several meter thick sandy facies of the Pliocene sand and gravel which contained a weak paleosol. Particle size analysis revealed that the upper unit exhibited texture similar to the overlying loess units, with unimodal silt comprising greater than 95% of the clay-free …

Direct Drilling On Sandplain Soils., Carmel Schmidt

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 …

Busselton, Margaret River, Augusta: Land Capability Study, Peter J. Tille, Neil Clifton Lantzke

Land resources series

The study was done to ensure that information on the area's land resource, and its capability, is available for land use planning. This information will assist planners to make decisions which can allow for the optimal development of the land while avoiding land degradation or land use conflicts. A map showing the distribution of land units defined according to soil type, topography, drainage and wind exposure was prepared at a scale of 1:50,000. From this map a smaller scale, less detailed land systems map was drawn. Land capability, the ability of land to sustain a specific use without undesirable on-site …

An Economic Model For Evaluating Strategies On The South Coast Of W.A. Which Reduce Wind Erosion : Documentation, A D. Bathgate

Resource management technical reports

The sandplain region on the south coast has predominately sandy soils which are subject to erosive winds when ground cover is likely to be scarce. This can often result in production losses of crop and pasture. There is concern that wind erosion will lead to the depletion of the soil resource in the long term. The model is multi-period linear programming with a planning horizon of 10 years. Effects of wind erosion on production can be imposed on the model for the first five years after the erosion event.
