A Technical Report from The Bartlett Tree Research Laboratories
Plants are one of the few organisms that produce their own food. They do this by converting carbon dioxide and water into carbohydrates in the presence of sunlight through the photosynthetic process. In addition to water and carbon dioxide, there are 14 more essential elements required for photosynthesis, growth, defense, and reproduction. Each one of these nutrients is therefore critical in the physiology of the plant.
