This activates enzymes that are responsible for the reduction of nitrate NO3- to nitrite NO2-, therefore in molybdenum deficiency nitrate is accumulated in plant tissues. It is required by the rhizobium bacteria for nitrogen fixation in legume. Boron (B): The ionic form of this nutritional element is B4O7—. Boron activates certain enzymes and participates with sugars in producing complex compounds (lignine) that are responsible for the thickening and hardening of cell walls. It participates in the process of producing the rhizobium nodules that are responsible for the nitrogen fixation of legume roots.
