إنجليزي. Potassium Q/I relationships were investigated by horizon on five soil profiles from the submountainous rainfed region of Punjab. The dominant minerals of the 2 m fraction were illite, kaolinite, smectite, quarz, chlorite and vermiculite. The equilibrium potassium activity ratio, ARek, changed with depth and was positively related to the sand fraction and negatively to the clay fraction. The potential buffering capacity, PBCk, increased with soil depth in three of the five profiles. Clay content of the soil profile was found to be a good indication of PBCk (r

I minerali dominanti della frazione 2 m erano illite, caolinite, montmorillonite, quarzo, clorite e vermiculite. La proporzione dell'attivita' del potassio in equilibrio, ARek variava con la profondita' ed era correlata positivamente con la frazione di sabbia e negativamente con la frazione di argilla. La capacita' tampone potenziale, PBCk, aumentava con la profondita' in tre dei cinque profili. Il contenuto di argilla del profilo del suolo si e' dimostrata una buona indicazione di PBCk (r
