Molybdenum (Mo) is a trace element but it has a big job. A good, albeit small, supply of molybdenum improves nitrogen uptake and conversion in plants.
Playing a key role in a wide range of processes within the plant, boron (B) is a micronutrient that is essential to crop health.
It is important to the cellular structure of the plant, contributing to cell wall formation and stability. It is a factor in cell division and elongation, protein synthesis, metabolism and transport of sugars and starches, hormone formation, and nodule development in legumes. Given its role as an integral component of the cell wall, boron is involved in the wound healing process, repairing cell walls damaged by hail or by chewing insects.
