Project Summary

The use of micronutrients for soybean has been proposed in recent years particularly for high yield environments where yield responses to these nutrients may be higher. However, there is limited research in Kansas for soybean under optimum yield environment. Additional research is also needed under no-till systems where plant availability from the soil of some nutrients may be altered affecting yields. Increased nutrient demands from more intensive cropping practices and high yielding potential crops may also require additional micronutrient for optimum yield. The overall objective of this study is to evaluate soybean response to secondary and micronutrient fertilizer application to maximize yields.

Project Objectives

1. Assessment of soybean grain yield response to micronutrients with emphasis on high yield environments.
2. Verify potential soil parameters that could be related to responses to secondary and micronutrients (B, Cu, Mn, S and Zn).
3. Evaluate tissue testing as a diagnostic tool to explain responses to micronutrient application.

Project Deliverables

Progress of Work

Yield response showed no effect of fertilizer application between treatments neither across locations. The application of micronutrients tended to increase yields in comparison to the control but no significant difference was observed by any individual nutrient or blend of nutrients. A clear trend can’t be seen for the element concentration in tissue sample except for Zn. The same trend for Zn was found for grain samples. For soil test changes comparing individual elements and blend of the same, there was no evidential trend for any of treatments applied.
