Notice to Industry – Tolerances for micronutrient fertilizers
October 12, 2017: The Canadian Food Inspection Agency (CFIA) is re-establishing tolerance levels for micronutrient fertilizers. The tolerances will be phased in over the next two years.
Micronutrients are plant nutrients that are required in small amounts. A lack of micronutrients can negatively affect plant growth and crop yield. However, too many micronutrients can also have adverse effects on animals, plants and the environment.
To mitigate the risks of over-application, the CFIA regulates micronutrient fertilizers. The tolerances will provide clarity for the regulated parties, facilitate compliance verification and enforcement and improve compliance rates in the marketplace.
The tolerances are based on scientific evidence and modern manufacturing practises, and are in line with international standards.
Products with micronutrients will continue to require labelling in English and/or French to inform customers of all safety information.
