The effects of Mn, Fe, Zn, Cu and B deficiencies and Mn, Fe, Zn, Cu, B, Mo, Al, Cr, Co, Ni, Se, Sr, Hg, Pb, Cd, and Ba excesses on visual symptoms and mineral concentrations in Sorghum [Sorghum bicolor (L.) Moench] plants grown in nutrient solutions were determined. Except for plants grown without B, Cu, and Fe, plant growth was inhibited by each mineral element treatment. Even though sorghum plants manifested distinctive visual symptoms for each element deficiency or excess, symptoms of excess Mo and Se resembled those of P deficiency and symptoms of excess Al, Cu, Co, and Ni resembled those of Fe deficiency. Concentrations of many of the essential mineral nutrients taken up by the plants were affected by the stresses imposed by deficiencies or excesses. Concentrations of the nutrients were affected more extensively in roots than in leaves.
