A static approximation in the study of the contribution of organic matter and clay to the cation exchange capacity of the ferralitic soils of Angola


, : A static approximation in the study of the contribution of organic matter and clay to the cation exchange capacity of the ferralitic soils of Angola. Garcia de Orta Serie de Estudos Agronomicos 20(1/2): 15-30

The relationships between the clay (A) and organic carbon contents (C) and cation exchange capacity (T) of 1380 soil samples representing the Ah, AB, BA and B horizons of 315 profiles of ferrallitic soils from Angola were examined using a multiple linear regression analysis. The samples are grouped into weakly ferrallitic soils (FF), typo-ferrallitic soils (FT) and psamoferrallitic soils (FG).

CEC was significantly correlated with clay, silt and organic-matter content, clay contributing most. The equation CEC = 0.51 clay + 4.12 OM was more suitable than one that included the silt factor.

Effect of organic matter content on CEC was greater than that of the mineral fraction in rankers and brown earths and, to a lesser extent, in lehms and alluvial soils. In brown earths, the CEC of silt, clay and organic matter was respectively 7-17...
