Experimental Summaries - Plant Research

Hoegrass tolerant ryegrass. Herbicide incorporation. Plant growth one season after herbicide use. Soil activity of glyphosate. Growth of lupins on plots treated with herbicide for each of the two previous seasons - Trials carried out at Geraldton, Wongan Hills and Wickepin measured the amount of pasture produced on plots that had been treated with herbicides while in crop the previous season.

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.

Survey details: Area covered - Katanning and Narrogin District Office (DO) areas. Sampling period - Mid …
