Despite a diverse array of micronutrient fertilizers is manufactured in the world, plant nutritional disorders remain a challenge for many growers. In Brazil, boron (B), zinc (Zn) and manganese (Mn) are the most limiting micronutrients to citrus production. In the soil, B is prone to leaching losses and the metallic nutrients are less available to the plants due to the lower mobility and high fixation to the colloids of the clay fraction. Therefore, foliar applications have represented a major s
