Potassium soil test levels that are high to very high in Virginia are associated with heavier textured soils, i.e. silt loams and clay soils. Many sandy and sandy loam soils do not have adequate cation exchange capacity to hold enough K to reach a high soil test level. Therefore, potassium soil test levels will decline more rapidly than P. Potassium removal rates are such that not enough K can be supplied in starter or pop-up fertilizers to supply plant needs and yield reductions will be seen if no other fertilizer is applied.

grower. Overall, a comprehensive soil testing program combined with appropriate fertilizer sources, application rates, and application methods will enable growers to manage one of their greatest input
