The investigation was made on the locality Aleksa Santic in SAP Voivodina (SFRY) where was presented the chernozem of loessial plateau with differences in the ground heights about 10 m (peak elevation 111,0 to 121,0 m). The taking of samples was done on 4.572 ha where 1.143 samples were attained. The attained level of easy accessable potassium was averagely 20.3mg and it could be classified in the group of high providencess. The highest percentage of samples was in the group of 10 to 20 mg, which was 57.30 % or totally 2.620 ha and then followed the group of more than 20 mg and 42.40 % or 1.938 ha, and the smallest group of 10 mg and 0.30 % or 14 ha. The influence of ground height to the content of easy accessable potassium did not show the significant differences in relation to the medium values, which could offer greater possibilities for locating control parcels in "System of fertility control of soil". If was noticed the weak decreasing of potassium content with increasing of ground peak elevation, which was in contrary to phosphorus tendency.
