Abstract
Fifteen of the sixty elements that have been positively identified to occur in plants are considered essential to plant life. The essential elements are divided into major and minor (micro-nutrient) elements depending on the quantities they require for plant growth. Molybdenum is the latest addition to the micro-nutrient group of essential elements. Traces of Molybdenum are essential for plant growth. It is considered to be necessary for the fixation of atmospheric nitrogen in the root nodules of legumes and for the reduction of nitrates in all plants. Nitrates taken up by the roots must be reduced in the leaf to build up protein. If Molybdenum is lacking, nitrates accumulate unused in the plant and the foliage assumes an appearance somewhat similar to that produced by actual nitrogen deficiency.
