Estudando amostras superficiais e amostras do B2 de perfis com B textural e B latossólico, verificou-se em cada caso a existência de correlação altamente significativa entre o pH e o grau de saturação em bases. A uma mesma saturação em bases, o pH mostrou-se mais elevado para as amostras do horizonte B2 de solos com horizonte B latossólico, mais baixo para o B2 de solos com horizonte B textural e intermediário para as amostras superficiais dos dois grupos de solos.
Upon studying the surface samples and samples for B2 horizon of soils with an argillic or latosolic B horizon, it was stated that in either case the relationship between pH and the base saturation degree was highly significant. However, the calculated regression equations were different and showed that, at the same base saturation degree, pH is higher for the B2 horizon of the latosols and lower for the B2 horizon of the soils with an argillic B horizon; for surface samples, the pH values were intermediate.
