“…According to Langmuir (1997), CEC values related to kaolinite range from 3 to 15 cmol c /kg, which is strongly pH dependent, while for illite it ranges from 10 to 40 cmol c /kg, which is slightly pH dependent. According to Rieuwerts (2007) and Coringa and Weber (2008), well drained soils of humid tropical regions, such as those studied in this work, are intensely weathered and dominated by minerals with variable load, as previously proven, which is responsible for low CEC values, which could vary with pH.…”

“…PZSE is a pH value where the salt concentration of the solution in a soil suspension has no charge effect on the surface of soil particles. According to Silva et al (1996) and Coringa and Weber (2008), the comparison between soil pH and PZSE allows to define whether the net surface charge of the particles is positive (pH < PZSE), negative (pH > PZSE) or zero (pH = PZSE). Soil PZSE depends on the content and degree of decomposition of organic matter and mineral composition of the clay fraction.…”

“…Como os solos apresentaram valores de Ki próximos possuem graus de intemperismo semelhantes, sendo assim, a variabilidade dos atributos químicos e físicos pode, então, ser melhor explicada pelo fluxo de água é condicionado pelo relevo (Coringa & Weber, 2008 (2) consistente nos valores dos atributos cristalográficos da hematita e goethita, de acordo com a profundidade do solo e a posição do perfil na topossequência (Ghidin et al, 2006).…”

“…Resultados da determinação dos parâmetros físico-químicos do solo. PESN também tem importante impacto nas propriedades de carga do solo, uma vez que a diferença entre o PESN e o pH do solo em água determina o sinal e a magnitude da carga variável presente(CORINGA;WEBER, 2008). O valor encontrado para o PESN foi de 3,6 (Figura 27).…”
