- Be in forms that cannot be assimilated by the plant (blocked).
- In high-yield intensive crops, microelement extractions are also higher.
- Tendency to use more and more concentrated fertilizers with fewer micronutrients versus less concentrated fertilizers that usually have more micronutrients.
- Less use of organic fertilizers (they present microelements in assimilable forms)
