Superphosphate For Wheatbelt Pastures : Rates Of Application, Walter Jacob Cox

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE Western Australian soils are low in phosphorus, frequent applications of superphosphate are required for both crop and pasture production. The recommended rates are determined from the results of field experiments that test different quantities of super and measure the extra yield.

This article discusses the recommended rates of superphosphate in relation to soil type and superphosphate history. Methods of application and time of topdressing are also discussed.

The Long Term Effects Of Frequent Cropping, Stanley Thomas Smith

Journal of the Department of Agriculture, Western Australia, Series 4

AGRICULTURALLY speaking, few Western Australian soils are more than 50 years old. We have the responsibility of preserving them for farming—not for one man's lifetime, but for centuries.

The aim of this article is to demonstrate that cropping and cultural practices do have some effects on the soil, and that these effects should be considered when choosing a farm rotation.
