Abstract
This NebGuide discusses the availability of and the need for potassium in Nebraska soils
Potassium (K) is an essential nutrient absorbed from soils by crops in relatively large amounts. Therefore, it is classified as a major nutrient. Although large amounts are absorbed, potassium is not necessarily needed in a fertilizer program. Numerous studies conducted with all major crops have definitely shown that adding potassium to a fertilizer program does not lead to yield increases on the large majority of soils in Nebraska.
