Abstract: The objective of this work was to estimate and compare potassium adsorption in contrasting soils (sandy and clayey) by estimating the amount of potassium adsorbed to two different soil textures. This work was carried out in the soil chemistry laboratory of the Federal University of Mato Grosso UFMT campus of Sinop. Five doses of Potassium Chloride (0, 40, 80, 120 and 160 kg ha-1) and two classes of soils (sandy and clayey) were defined. Potassium adsorption in the soil was determined by the Batch method. Effective CTC and clay activity influence soil K adsorption and adsorption of K to solid soil gradually increases as soil K doses increase.


Key words: batch, contrast, influence
