Historical soil test information for southern Idaho surface soils (0-12") shows that
extractable K concentrations declined from 400-plus ppm in the late 1960's to 100-200 ppm
today. Potatoes, silage corn, and alfalfa can remove nearly 400 lbs K/A-yr when high yields
are achieved. Many irrigation waters contain 28-56 lbs/A-ft soluble K which is not sufficient
to maintain soil test K concentrations with high K removal rates.
