THE mineral nutrition of crop plants is of particular interest at this time. The recent developments in physics and chemistry provide an opportunity to use new and improved techniques in studying significant factors in soil fertility and plant nutrition. It seems that the energy properties of the nutrient ions afford a new and a very significant factor to consider in nutritional studies. Chemical analysis has been made of a ,large number of food plants, but there is very little information concerning the chemical analysis of the cotton plant as the vegetative part of the plant is not generally used for feed. A large amount of commercial fertilizer is used in the production of cotton in the southeastern states, and it is desirable to have more definite information on the mineral nutrient requirements of the cotton plant. In his review and compilation of the chemical composition of plants Beeson (i) has covered a large number of plants grown over a wide range of conditions.This type of information gives a general idea of the relative amount of the different nutrients utilized by plants. It is generally recognized that there is a very wide variation in the chemical composition of different parts of the cotton plant. Since it did not seem desirable or feasible to make a chemical analysis of various parts of the cotton plant, it was decided to collect samples for analysis after the bolls were well formed and the older bolls were beginning to open. The chemical composition of 28 samples of cotton plants selected from different soil types is included in Table i. .
