Soybean nutrient uptake and partitioning models are primarily built from work conducted in the 1960s; however, recent work highlighted the need for large increases in soybean nutrient uptake recommendations. This and other work indicate a critical need to update recommendations for today's soybean varieties, production practices, climate, and economics. All agronomic inputs (biologicals, plant growth regulators, fungicides, etc.) and economic thresholds are based on crop growth stage; however, with larger farms, scouting has become increasingly cumbersome. Plant phenology models have not been validated in the variable climate of the north central Corn Belt. This large-scale investigation...
1. Validation of a soybean growth model (SoySim)2. Recommendations for maturity group choice across a wide range of planting dates for the Northern States.
The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
