Potassium, as a non-mobile nutrient, is commonly thought to stay put in soils; however, this should not imply that soil test K levels are constant throughout the year. Seasonal variability in soil test K from spring to fall (often higher in spring and lower in fall) creates issues for soil sampling and interpreting soil test results for fertilizer applications. This session will cover soil K dynamics and approaches to mitigate seasonal K variability to improve nutrient management decisions.
