Nutrient disorders in plantation eucalypts

Summary. The purpose of this manual is to illustrate the symptoms associated with essential nutrient deficiencies of those species of eucalypts which are now widely established in plantations in P.R. China, the Philippines and other countries. The manual focuses on three tropical/subtropical species (Eucalyptus grandis, E. pellita and E. urophylla) and one temperate species (E. globulus). Techniques for identifying nutritional disorders are explained and deficiency symptoms are described in detail for twelve elements. These symptoms can be used to help determine deficiencies in nurseries or young plantations. However, symptoms are a guide to nutrient deficiencies and should be used with other diagnostic tools. For this reason leaf analysis standards are included
