If organic farm methods for nutrient management such as cover crops and application of compost can’t resolve soil deficiencies, micronutrients may be allowed for use.
When are synthetic micronutrients allowed for use?
Synthetic micronutrients are allowed only in cases of clearly document soil deficiency of a specific nutrient. We accept soil or plant tissue tests as documentation prior to approval for use. In addition, you must document the nutrient requirements for the crop.
As with all agricultural inputs, never risk your certification. For all non-OMRI or non-WSDA approved materials, request approval from your client service team. Never use an unapproved micronutrient until after OTCO review and receipt of approval.
