I’m dealing with a micronutrient deficiency. What are my CNG-approved options?

Synthetic micronutrients may only be used for fertility, they must be OMRI-listed, and there must be a documented deficiency in the form of a soil or tissue test. Remember to ask: 

Is this micronutrient…

  1. …being applied for crop/soil fertility?
  2. …OMRI-listed?
  3. …documented by a soil or tissue test?

Therefore, even if a producer is using an OMRI-listed synthetic micronutrient they must ALSO document the need for the deficiency in order to use the product. 

This applies to the following nutrients:

  • Boron
  • Zinc
  • Copper
  • Iron
  • Manganese
  • Molybdenum
  • Selenium
  • Cobalt
