Nutrient solutions have been made use of to a considerable extent in endeavoring to determine the specific role of certain nutrients as well as questions of nutrition in general. It is known that iron, although used in small quantities, is essential for chlorophyll production. The present work is a study for the purpose of ascertaining the value of different amounts of iron to an otherwise balanced solution. This feature has suggested itself in that the majority of such solutions do not contain definite amounts of iron, but are simply designated by a “trace.”
