POTASH 23 Potash P otash is an impure combination of potassium carbonate & potassium (K) salts. Over 90% of potash is used as fertilizer and is one of the three primary agricultural nutrients (N-P-K). All commercial potash deposits come originally from€evaporite deposits and are often buried deep below the earth' s surface.
