The effect of soil K supply and K fertilization on the crop yields and quality as a result of three crop rotation field experiments on sod-podzolic loamy sand soil is presented. The efficiency of potassium fertilizer rates was remarkably dependent on soil K supply level. An optimal potassium content in soil (K2O) was found within the range of 168-248 mg kg*[-1) and the highest net return provided the application of 60-90 kg ha*[-1) of K2O.
