A systematic examination was undertaken of absorption and accumulation of the biologically essential elements by the tobacco plant when grown to the flowering stage. Both complete and micronutrient deficient cultures were studied. The basal nutrient solution employed was an approximately maximal yield solution of minimal salt content. Its composition had been determined in consecutive tests each spring since that of 1945, using both increased and decreased quantities of individual salts to determine maximum possible yields with minimal supply of salts. The experimental installation was kept unchanged during this time and a uniform procedure used in handling seedlings. Its composition could be assumed to have meaning only for the one variety and environment.
