1. Evaluation of soybean response to in-season potassium fertilizationIn-season application of potassium (K) fertilizer may offer an alternative to remediate deficiencies developed during the growing season. The objective of this study was to determine soybean (Glycine max) response to topdress K application timing under deficient soil conditions. Treatments included a control (0 lbs K2O acre-1), 50 lbs K2O acre-1 pre-plant incorporated, and 50 lbs K2O acre-1 in-season broadcasted at the... D.A. Charbonnier, D.A. Ruiz diaz, M.A. Coelho |
2. Investigating Potassium Fertility in Indiana: K Rates and Nutrient InteractionsAdequate potassium (K) nutrition is critical for optimal plant growth and yield production in both corn and soybeans. Ongoing trials across the state of Indiana have been investigating K rate response in corn and soybeans in different environments. Treatments range from 0-180 lbs K2O/ac as potash. Results from these studies will be discussed. Additionally, new in 2025, NxS and NxK trials were conducted to investigate the effect of K nutrient interactions on corn yield. Treatments in... D.
