Toxicities and Tolerance of Mineral Elements Boron, Cobalt ...

The minerals boron (B), cobalt (Co), molybdenum (Mo) and Nickel (Ni) are beneficial to plant in trace amounts, but excess levels of these cause toxicity limiting crop production. An attempt was made to review the phytotoxicity symptoms, effects on growth and physiology and tolerance and amelioration of these toxicities in crop plants.
