Franco, E.P.C.; Ricardo, R.P., 1998: 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. 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...

Hosking, J.S., 1948: The cation exchange capacity of soils and soil colloids. 2. The contribution from the sand, silt and clay fractions and organic matter. The silt and sand fractions of the various soils studied were demonstrated to possess appreciable cation-exchange capacity related to the presence in these fractions of high concentrations of the clay minerals, which are distributed throughout all...

Parfitt, R.L.; Giltrap, D.J.; Whitton, J.S., 1995: Contribution of organic matter and clay minerals to the cation exchange capacity of soils. The cation exchange capacity (CEC) at pH 7 was measured for samples of 347 A horizons and 696 B horizons of New Zealand soils. The mean CEC was 22.1 cmolc/kg for the A horizons and 15.2 cmolc/kg for the B horizons. Multiple regressions were carrie...

Sx. Arnaud, R.J.; Sephton, G.A., 1972: Contribution of clay and organic matter to cation-exchange capacity of chernozemic soils. Multiple regression equations showed that variations in organic matter and clay content accounted for 54 to 89 % of the variation in the CEC of rego, orthic and eluviated subgroups; the inclusion of an organic matter/clay content interaction term...

Lavti, D.L.; Gandhi, A.P.; Paliwal, K.V., 1969: Contribution of clay and organic matter in the cation exchange capacity of Rajasthan soils. 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.

Wright, W.R.; Foss, J.E., 1972: Contribution of clay and organic matter to the cation exchange capacity of Maryland soils. The relative contributions of clay and organic matter to total CEC were measured using multiple regression analysis. The average exchange capaci-cities of organic matter and clay from AP horizons were calculated as 295and41 meq/100g, respectively....

Hallsworth, E.G.; Wilkinson, G.K., 1958: The contribution of clay and organic matter to the cation exchange capacity of the soil. Partial regression analyses were made to calculate the cation-exchange capacities of the clay and organic matter in different soil groups from New South Wales. The exchange capacity was determined entirely by the clay and organic matter in stony d...

Sahrawat K.L., 1983: An analysis of the contribution of organic matter and clay to cation exchange capacity of some philippine soils. Simple and multiple regression analyses were used to examine the relationships between cation exchange capacity (CEC), organic matter and clay content of 40 surface Philippine soils to determine the contributions of organic matter and clay to CEC....

Sanchez, B., 1969: Contribution of silt, clay and organic matter to the cation-exchange capacity of acid soils. 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...

Bhatnagar, R.S.; Atri, S.C.; Mathur, G.S.; Choudhary, R.S., 1977: Contribution of organic matter and clay to the cation exchange capacity of the Rajasthan canal soils. The cation exchange capacity (CEC) of the Rajasthan canal soils showed a close correlation with clay, silt and organic matter content (OM) respectively. Clay had the predominant effect on CEC; this was followed in decreasing order by OM and silt....
