This is often routinely done in the Central and Mid-Western States and Provinces where soil and climate conditions are more predictable than those in Prince Edward Island. Unfortunately, soil tests for most micronutrients appear to be of limited value in predicting micronutrients deficiencies in the Atlantic Provinces. At present, there appears to be little justification for widespread use of micronutrient supplements in fertilizers, except in cases where soils have been overcropped and degraded. Add micronutrients to fertilizers only at recommended rates. Just because a little is good, it doesn't mean a lot is better.
Toxicities can easily occur with some micronutrients.
Monitor the micronutrient status of fields each year by plant tissue analysis. If deficiencies are found, they can be corrected that year by foliar application of nutrients. In any case, the confirmation of deficiencies can be useful for subsequent crop years. Website architecture and construction by Reinvented Inc. for the Government of Prince Edward Island, Canada.
