AUTOMATED SYSTEM FOR INDUCING NUTRIENT DISORDERS UTILIZED IN GROWER-BASED GUIDES: EXACUM AFFINE 'ROYAL DANE BLUE'
Growers must be equipped with cultural information including the ability to recognize and characterize nutrient disorders and critical leaf tissue ranges. We created an automated irrigation system in order to grow plants in silica-sand culture to induce, describe, and photograph symptoms of nutritional disorders. To date, we have induced disorders in 43 types of plants. Description of how the system operates, critical values for Exacum affine Royal Dane Blue, along with the development of grower-based electronic books created with iBooks Author in order to aid growers in diagnosing nutrient disorders are presented.
