Once the 100 bu/A soybean yield barrier was broken in yield contests, many others have attempted to repeat this feat. We are not proposing to break 100 bu/A soybean yield with this proposal, but rather to provide a better understanding of new or novel management practices that have the potential to substantially increase soybean yield. We plan to examine practices that are novel, counter to traditional thinking, or have shown promise in the lab or greenhouse but are not yet proven in the field at production scale. Approach We plan to apply nutrients to both sides of the soybean row by subsurface injection later in the season, on soils that have a soil test nutrient status such that a yield...
