Soil Acidity Survey. Lime Responses In The Central Wheatbelt, P J. Dolling

Experimental Summaries - Plant Research

Introduction: In 1984 a project commenced to examine the influence of soil acidity on barley production in the main barley growing areas of Western Australia. To carry out some of the projects objectives a soil survey was carried out.

Aims: 1. To select nine sites for liming trials in 1985. 2. To obtain more information about the soil acidity problem in the medium rainfall region of W.A. 3. To determine if there is a relationship between the pH and aluminium content of the soil.

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 …

Residue Trials, Herbicide Incorporation And Leaching Of Chlorsulfuron, T Piper

Experimental Summaries - Plant Research

Residue Trials: Breakdown rates have been established for trifluralin at Wongan Hills and Avondale over the past two seasons. The decay curve follows a hyperbolic curve rather than the expected exponential curve with constant half life, probably due to the considerable loss of chemical by volatalization in the first few days, before biological decomposition takes over as the main breakdown factor.

Experimental Summaries - Plant Research

CONCLUSIONS This trial has confirmed the field observation that 2,4,5-T whilst giving good initial control of Pennyroyal, fails after a number of years. Round up has a far longer term effect. This can only be attributed to a more complete initial kill as both herbicides are essentially non residual. Further work needs to be conducted on Round up in combination with soil residual chemicals or multiple applications to overcome the problem of reinfestation from seed reserves. 81A1 -01
