Despite the extensive effort devoted to developing tools for making corn N fertilizer recommendations, most tools have not proven to perform well over a wide range of soils and climate conditions. Research in recent years is showing how important with-inseason weather and site-specific soil information is for making better estimations of crop N need for any given year. The presentation will show how well the tools and soil and weather-adjusted tools performed for making corn N recommendations. Findings will help guide future development of N fertilizer recommendations that are responsive to both spatial and temporal variability between and within crop production fields.
