Small, but Mighty – Micronutrients Needed for Macro Yields

A combination of soil and tissue testing provides the most accurate picture for what a farmer needs to build an efficient crop fertility program.

While the “micro” in micronutrients may imply “of little importance,” a deficiency in any macro or micronutrient can significantly lower yield. Boron, copper, chlorine, iron, manganese, molybdenum, nickel or zinc are all as essential as nitrogen or phosphorus, although in comparison, only required to apply at a “micro” rate.

Micronutrients play a key role in many plant functions, from root growth to flower formation and from photosynthesis to fruit set. Deficiencies in any one micronutrient adversely affect plant health, so it’s important to know what’s in your soil, if it is in a form that is available to plants and what nutrient management strategies need to be implemented to ultimately achieve a strong, healthy crop.
