Abstract
Plants have the marvelous ability to take up inorganic mineral nutrients as atoms or simple molecules and process them into proteins, enzymes, and other organic forms. This paper reviews the 14 essential mineral nutrients, their roles within the plant, their target concentrations in tree seedling nursery culture, and their effects on seedling growth and performance after planting. Three areas of active research in tree nutrition over the past 20 years with relevance to the Pacific Northwest are discussed: steady state nutrition, exponential fertilization and nutrient loading; adaptation to nitrogen form in forest soils and organic nutrient uptake; and variation in nitrogen uptake within species.
