Aerial Spraying Trial., G A. Pearce

Experimental Summaries - Plant Research

Conclusions 1. The volume of application with water affected the results obtained. The visual results of Treatment 1 suggested it was not an acceptable commercial result and the plant counts support this conclusion. Treatments 2 and 3 looked very similar and were very similar and were very acceptable results. 2. The height of spraying affected the results in that where the plane had to start climbing to pass over trees, the effectiveness dropped off. 3. Spray drift could be a problem because of the risk of causing damage to trees and native vegetation. Severe damage was seen on trees at …

The Effect Of Soil Acidity On Crop And Pasture Production., W Porter, R Klemm

Experimental Summaries - Plant Research

SUMMARY The effects of lime and molybdenum applications on wheat and subterranean Clover were studied further. Wheat. In relation to lime use, my aim is to develop soil tests to be used to predict when a soil requires lime to produce maximum yield, and to predict the optimum rate of lime. Using the results from field trials commenced in 1980 and 1981 the soil parameters which may be used to predict lime responses in wheat have been narrowed down. From the relationships between soil data and lime responses it appears that soil ph (measured in 1:5 H20 or 1:5 N …
