This practical book (and eBook) explains what soil tests are, when they should be used and how to understand and interpret soil test data. It discusses what limits their application and provides a structured approach to nutrient management for Australian soils. The first three chapters review the general principles and concepts of soil testing, factors affecting soil test interpretation and soil sampling and handling procedures. The next two chapters describe morphological indicators of soil and include colour plates of major Australian agricultural soils. This book is no longer available in a print edition but the eBook is available from eRetailers (e.g. Apple Store, Google Play) or, with institutional access, through CSIRO Publishing [369 pages]. #
