N-P-K FERTILIZERS - College of Agriculture & Natural Resources
www.canr.msu.eduMost potassium fertilizers are highly water soluble. Like NH 4 +, K+ is held in the soil by clay and organic matter. Unlike NH 4, however, K is not converted to a more mobile form. Potassium stays relatively close to the initial point of application. Leaching of K is not generally a problem, except on very sandy or gravelly soils, due to ...
