Resumen

The dynamic of potassium in soils is studied after different rates of potassium fertilizar are added to the soil. The parameters abtained from the Q/I relationship and the changeable potassium in soil are calculated (AR^, PBC'', AK°, AKj^ and AK^). The influences of the quantity (Q), intensity (I) and capacity (O/I) factors upon the equilibrium time, fertilization and the soil / solution rate are shown. The resülts found in deficient potassium soils allow to understand in a better way the competition between potassium and the complementary cations as well as the potassium fertilization in these soils.
