Fertilisers containing small quantities of copper and zinc are widely used for crops and pastures in Western Australia, and the benefits resulting from the use of one or both of these trace elements—especially on sandy or gravelly soils—have been demonstrated in numerous trials during the past 20 years. It is estimated that about 5,000,000 acres have been treated with copper and zinc in Western Australia in the ten-year period 1947-1956. In this article, an attempt has been made to answer some of the common inquiries made by farmers concerning the use of copper and zinc in cereal-growing districts where large areas of light land are being developed.
