Soil Potassium Availability: The Roles of Manure, Irrigation and Potassium Feldspar
December 17, 2019
Why do Nebraska soils tend to have high potassium (K) availability, even with high yields and often without fertilizer K application? Why are yield responses to fertilizer-K infrequent?
What’s New with K Fertilizer Use?
April 5, 2018
Three studies with a total of 50 trials applying K at various rates to corn verified that the likelihood of a profitable response is very low if the soil test level is above 125 ppm.
