Beneficial Elements

BENEFICIAL ELEMENTS

The  elements,  the  essentiality  of  which  for  growth  and metabolism has not been unequivocally established, but which are shown to exert beneficial  effects  at  very  low  concentrations  are  often  referred  to  as  beneficial elements, or potential micronutrients. The beneficial effect of  these nutrients may be  due  to  the  ability  of  these  elements  affecting  the  uptake,  translocation  and utilization of  the essential elements. They may be essential only  for certain plant speces or under specific conditions.  

Eg : Silicon, vanadium, cobalt and aluminium
