Product Description

This manual is part of a 5-book series called Plant Nutrient Disorders that aims to help farmers, advisers and students to identify nutrient deficiencies and toxicities in a wide range of crops and pasture plants. Each book describes and shows, with the aid of coloured plates, typical symptoms of the common nutrient deficiencies and toxicities found in commercially cultivated plants. Ways of distinguishing symptoms caused by a nutrient deficiency, toxicity, or some other problem such as a disease, herbicide damage or moisture stress, are explained.

These methods are a distillation of the experiences of nutrition chemists, advisory horticulturists and agronomists from the New South Wales Department of Agriculture who collaborated for more than thirty years to provide a diagnostic service to the farming community. This consultancy service ceased in 1988, but it is hoped that the skills developed for diagnosing nutrient disorders in plants will be passed on through each of these books.

Most of the coloured plates used in the manuals are of field specimens and, in many cases, leaf analysis has been used to identify the problem. The photographic and analytical records which are the primary sources of material in these books go back to 1958 and represent one of the oldest and most crop diverse collections of its type in the world.

This series provides leaf analysis and sampling methods for the most commonly grown crops in Australia, as well as for some poorly documented species. Where months are mentioned they refer only to the southern hemisphere. For northern hemisphere readers, the corresponding time of season or stage of crop development is shown in brackets. The booklets explain in everday language the main uses for leaf analysis, how to interpret a leaf analysis report and the main shortcomings of the procedure. The information contained in this series should be helpful to anyone who wishes to understand crop nutrition better and build reliable diagnostic skills.
