Loblolly pine ( Pinus taeda L.) seedlings were grown in nutrient solutions each deficient in one of the essential elements. A description of observed deficiency symptoms is given for each essential element. Coloration symptoms are described by means of Munsell color charts and were tested for significance. Munsell color charts proved to be practical and consistent for color descriptions. Symptoms that proved to be unique were used in the development of a dichotomous key for the identification of essential element deficiencies.
