From the preface: "Author has had many valuable discussions with chemists working throughout Australia and New Zealand, as well as in other parts of the world. Much additional experience in the chemical and physical examination of soils and the chemical analysis of plant material has also been gained by his colleagues in the Department of Agricultural Chemistry of the University of Adelaide and the Division of Soils of the Council for Scientific and Industrial Research. This additional experience has led to many amendments in the original methods, to make them applicable, generally, to the wider range of soils encountered, while new methods have been added, for determinations not previously included. As a result of the favourable reception accorded to the earlier publication, and in response to numerous requests, it has been felt desirable to compile a new edition of the methods in use, incorporating the additional material available. With the exception of two or three of the less common determinations, all of the methods included in the present publication are in actual use in the laboratories of the Waite Institute and can be recommended to give accurate and reliable values for a wide range of samples."
