Work on micronutrient fertilizer response in corn has been neglected, despite the fact that micronutrients are expected to suffer from the same issues as P and K; decreases in soil quantities due to increasing yields over time, and in the case of sulphur, decreasing atmospheric deposition. In response to these developments, this project is building on previous starter fertilizer research by evaluating corn yield response and economic returns to the application of sulphur and zinc through pre-manufactured micronutrient starter blends as well as traditional starter fertilizer sources. It is also examining the importance of including potassium in sulphur and zinc fertilizer blends.
