Reference no: EM13173113

Given the cation exchange capacity of a soil sample, its clay concentration and the CEC of the clay be able to estimate the draction of CEC due to organic matter in the sample

CEC of soil sample = 25 Cmol(-) kg-1

Clay concentration= 25% = 250 g kg-1

CEC of clay= 80 Cmol(-) kg-1
