Three amendments (lime, dolomite and mixture amendment) at rates calculated to neutralize 100% and 150% of exchangeable hydrogen were applied to samples from soils incubated for 60 days. The responses on actual and potential pH, and hydrogen, calcium and magnesium exchangeables were assessed. The increment of actual pH showed differences between amendments and the order of response was lime > dolomite > mixture amendment. No difference between the applied rates were observed. The potential pH was more sensitive to the type and of rates amendment. All treatments reduced the level of unsaturation, although the full neutralization was not achieved with the tested rates. Increments of exchangeable calcium were observed in all treatments and the greatest calcium saturation was obtained when lime or mixture amendment were applied at the highest rate. Dolomite and mixture amendment significantly increased the content of magnesium regardless of the rate. The information presented here is useful for prescribing magnesic-calcareous amendments in soils of the flat Pampas of Santa Fe. El objetivo de este trabajo fue comparar el poder de neutralización de enmiendas calcáreo- magnésicas y evaluar su efecto sobre el complejo de intercambio catiónico en suelos de la pampa llana santafesina. Para ello, se aplicaron tres enmiendas (caliza, dolomita y enmienda mezcla) a dos dosis (neutralización del 100% y 150% del hidrógeno de intercambio). Se evaluó: pH actual, pH potencial, hidrógeno, calcio y magnesio intercambiable luego de 60 días de incubación. El pH actual no mostró diferencias entre dosis, mientras que el incremento de pH de las enmiendas fue caliza > dolomita > mezcla. El pH potencial fue más sensible al tipo de enmienda y dosis. Todos los tratamientos redujeron el nivel de insaturación, aunque ninguno neutralizó la totalidad del hidrógeno intercambiable. En relación con el calcio intercambiable, todos los tratamientos produjeron aumentos y la mayor saturación cálcica se obtuvo con la aplicación de caliza o enmienda mezcla con la dosis necesaria para neutralizar 1,5 veces el hidrógeno intercambiable. En cuanto al magnesio, las enmiendas dolomita y mezcla aumentaron significativamente el contenido independientemente de la dosis. La información aquí presentada es de utilidad para la prescripción de enmiendas calcáreo- magnésica en los suelos de la Pampa llana santafesina.
