Phosphorus/Potassium

Scientists meet to chart future course for improving P nutrition

A small group of internationally recognized scientists met recently in Kona Beach, Hawaii to brainstorm the future of potassium (K) nutrition of crops. The Frontiers in Potassium Science Workshop focused on creating a list of strategies for explaining and managing significant spatial and temporal variability in the contributions of fertilizer K and soil K to plant nutrition.

New choices for winning the nitrogen risk game

It is a well-known fact that rainfall has a lot do with nitrogen loss in Iowa fields. What was not clear before, was how rainfall could be used to determine if a certain field would be nitrogen (N) deficient. The recent influx of different predictive N tools has spurred renewed interest in using rainfall for assessing the risk of corn N stress or the likelihood of a yield response to N fertilizer.
