Add to ORKGBECAUSE 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
