Contribution of silt, clay and organic matter to the cation-exchange capacity of acid soils






An. Edafol. Agrobiol, 28: 14-23

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, 13-26 and 73-87 meq/100 g.
