MOLYBDENUM (Mo) 95.94 Atomic Weight
Molybdenum is a relatively rare element that is not found in its free form in nature. It’s primary benefit to plants is as a catalyst in assisting bacteria in the fixation and utilization of nitrogen. Plants cannot transform nitrate nitrogen into amino acids without Molybdenum. Legumes cannot fix atmospheric nitrogen symbiotically unless Molybdenum is present. Plants take up molybdenum in either a sodium molybdate or Molybdenum trioxide form.
