Molybdenum is a special nutrient for nitrogen fixation and absorption, reduction of nitrates to nitrites in the plant growing process and to allow bacteria to act in degrading nitrogen for bioavailability in nutrient synthesis.

It favors absorption and translocation of iron in plants. Its deficiency is similar to that of nitrogen, presenting chlorosis in adult leaves, associated with necrotic spots when there is a severe deficiency. Greenplants-Mo provides elemental molybdenum that forms part of the nitrate reductase enzyme that reduces nitrate ions to nitrite, although it may also help in purine degradation, such as adenine and guanine, due to it need as part of the xanthine dehydrogenase enzyme (Mendel and Muller, 1976; Perez Vicente etal., 1998).
