Micronutrients
Micronutrients are essential chemical elements, such as boron, zinc, and iron, required by plants in small quantities for healthy growth and physiological development.

Micronutrients act as vital co-factors for plant enzymes, influencing fundamental processes like photosynthesis, nitrogen fixation, and sugar transport. Providing an adequate supply helps crops to resist environmental stresses, reduces susceptibility to plant diseases, and enhances the overall nutritional value of the harvest.
These fertilizers are typically applied during specific growth stages or when visual symptoms of deficiencies, such as yellowing leaves or stunted growth, are observed. Foliar application is a common practice, ensuring direct and efficient uptake by the plant leaves, especially when soil conditions inhibit nutrient availability.
Common mistakes include applying fertilizers without soil or tissue testing and failing to calibrate equipment, which often leads to over-application. Since the threshold between deficiency and toxicity is quite narrow for many trace elements, precision in dosing is essential to avoid negative impacts on crop health and soil toxicity.
