Pasture Research Programme For The Medium Rainfall Zone Of Wa, P. Dixon

Experimental Summaries - Plant Research

Pasture Research Programme for the Medium Rainfall Zone of W.A. - Species Selection and Management Related in Particular to the Ryegrass Toxicity Problem Since the early 1970's much of the ryegrass based pastures in the Pallinup region have been affected by Annual Ryegrass Toxicity (ARGT). Control of ryegrass by herbicides invariably leads to a reduction in the stock carrying capacity of the pasture since currently available legume species fail to grow or persist. This tendency is particularly evident on the hard setting loam soils of neutral to alkaline reaction. The aim of this project is to find alternative pasture species …

An Assessment Of Wisalts Banks At Dangin, C J. Henschke, J A. Bessell-Browne

Resource management technical reports

This report compares two alternative approaches for the treatment and management of salt affected land at Dangin, Western Australia by determining whether there are benefits from a WISALTS bank system which would not accrue from standard soil conservation recommendations; comparing the costs and benefits of the two systems; and determining the nature of the effects of the two systems, particularly with respect to soil salinity.

A Description Of The Soils And Geology Of The Berkshire Valley Experimental Catchment, M R. Wells, D J. Mcfarlane

Resource management technical reports

Basic land resource data are provided in this report to assist an investigation of the effect of contour banking on surface runoff in the Berkshire Valley experimental catchement. Brief descriptions of the catchment's geology, soils and their inferred hydrological significance are provided and a 1:2000 scale map produced. Of major significance to the hydrologic study is the fact that soil depth and internal drainage conditions were found to be not related to landscape positions.

Infiltration Through Reconstructed Surface Mined Spoils And Soils, A. D. Ward, Larry G. Wells, R. E. Phillips

Biosystems and Agricultural Engineering Faculty Publications

An extensive series of tests involving reconstructed profiles of spoil and topsoil material from a Western Kentucky surface mine site was conducted with a laboratory infiltrometer system. Infiltration through the reconstructed spoil profiles was very slow despite the coarse nature of the material. Low infiltration rates could be attributed to the material having a well-graded texture and to the high densities of the profiles. Infiltration through topsoil horizons was controlled, for the most part, by conditions at the surface. Following wetting, infiltration rates were primarily controlled by the hydraulic characteristics of the less permeable sub horizon of the spoil material. …
