The recognition of symptoms on leaves and stems which result from nutritional disorders is a powerful tool in determining nutritional constraints to the growth of trees, especially when little other nutritional information is available. When used in conjunction with other information, such as soil parent material, climate, soil analysis, site history and nutrient (fertiliser) trials, it can often lead to rapid diagnosis of major nutritional constraints. The visual symptoms outlined in this book are a first step in alerting plantation managers to nutrient deficiencies they may encounter in the nursery and the field.
