Interpretive Summary:

Technical Abstract: Soil health and soil fertility tests, including interpretations, are largely viewed as independent activities. It is generally held that soil nutrient management decisions could be improved by integrating both soil fertility and soil health testing, but the relationships between these tests are still largely undeveloped. Research on phosphorus (P) and potassium (K) and sulfur (S) corn response plots are ongoing to identify possible relationships between these tests. This presentation will summarize 2018-19 data collected from over 50 fields located in central Missouri, northern Iowa, and South Dakota with a various range of soil fertility and soil health values. Crop and soil measurements were collected to evaluate crop P, K, and S response at the V6 corn developmental stage and at plant maturity. Analysis will include an evaluation of the impact of soil health on current fertilizer recommendations.
