Abstract

In order to establish the correlation between soil potential acidity and SMP solution pH, 472 soil samples from the Goiás State cerrado area were studied. Soils were analyzed for H + Al by the calcium acetate at pH 7.0, SMP solution pH, and water pH methods. Data showed a correlation between SMP solution pH and soil H + Al content (r²=0.82), allowing the potential acidity determination in laboratory substitution for the equation obtained (y = 222.54 + 29.83x - 164,7x^0.5).

KEY-WORDS: pH SMP; soil potential acidity; Goiás State cerrado soils.
