Abstract: Effects of regular K fertilization and liming on the easily available K content of a Haplic phaeosem soil determined in 0.01 M CaCl2 were examined in the B1740 type of the National Uniformed Long-Term Fertilization Experiment at Karcag. Close correlation (r=0.95) were found between the 0.01M CaCl2 and ammonium lactate acetic acid (AL; traditional method of Hungary) extractable K contents of soils. K fertilization increased significantly the amount of 0.01M CaCl2 extractable K. Liming decreased the amount of CaCl2-K. We can explain this by the changing of the rate of exchangeable K compared to exchangeable bases. CaCl2 extractable K was in good agreement with the exchangeable K content of soil and the agronomic K balance. We can conclude that CaCl2 method is suitable for the precise estimation of nutrient requirements.
