Boron (B) is a micronutrient critical to the growth and health of all crops. It is a component of plant cell walls and reproductive structures and plays a key role in a diverse range of plant functions including cell wall formation and stability, maintenance of structural and functional integrity of biological membranes, movement of sugar or energy into growing parts of plants, and pollination and seed set. Adequate B is also required for effective nitrogen fixation and nodulation in legume crops. The two common boron containing fertilisers are Borax and Boric acid and can be given through soil or as a foliar spray at critical development stages.
