Micronutrients: Small but Mighty

  • Boron. Boron is essential for healthy cell growth in plants and is important in the formation of pollen as well. Without pollen, many plants - including most important food wnd feed crops - would not be able to bear fruit and reproduce. A shortage of boron may also stunt the growth of plants. The benefits of boron are not limited to plants, either: Some nutritional research indicates boron may have a role in helping prevent osteoporosis.
  • Chlorine. Chlorine helps plants manage water stress and may help some plants resist fungal diseases. Farmers apply fertilizers containing chlorine typically to small grains like wheat.
  • Copper. In plants, copper is important mostly as a catalyst (it promotes chemical reactions without becoming part of the product of those reactions). Its indirect role is an important one, though: without it, plants will not develop normally. Copper is also important in the formation of protein pigments found in red blood cells, making it a key micronutrient for animals and humans as well as plants.

  • Iron. Like copper, iron serves as a catalyst, especially in the formation of chlorophyll. It also helps regulate certain plant enzymes, and promotes root function in legumes. The leaves of plants deficient in iron often turn pale green or even yellow, a signal that the plant isn’t forming chlorophyll properly. Farmers can apply fertilizer containing the proper form and amount of iron either to the soil or the foliage of the crops.
  • Manganese. Manganese is yet another micronutrient that helps plants synthesize chlorophyll, as well as helping regulate several important plant enzymes. In fact, it performs some of the same functions in humans. Making sure plants have enough manganese in their diets also helps make sure we have enough in ours.

  • Molybdenum. Molybdenum helps plants make efficient use of nitrogen and phosphorus. That makes molybdenum important for plants; when there’s enough molybdenum available, the plants are better nourished by primary nutrients. It’s also important for farmers. When the plants make better use of nitrogen and phosphorus, the farmer gets a better return on investment in fertilizer.
  • Zinc. Zinc plays key roles in human health and nutrition as well as in plants. It helps plants form proteins, starches, and growth hormones, and helps people grow normally and have healthy skin and bones. As with manganese, helping make sure plants have enough zinc helps make sure we have enough, too.
