Through increased use of soil testing and plant analyses, micronutrient deficiencies have been verified in many soils. Some reasons limiting the incidental additions of micronutrients include:
High-yield crop demands remove micronutrients from the soil
Increased use of high-analysis NPK fertilizers containing lower quantities of micronutrient contaminants
Advances in fertilizer technology reduce the residual addition of micronutrients.
