Question

Which soil test parameter, calculated as the ratio of exchangeable sodium to the total cation exchange capacity of the soil expressed as a percentage, is used to classify a soil as sodic when its value exceeds 15%, distinguishing sodic soils from saline soils on the basis of sodium's proportional dominance among exchangeable cations rather than total salt concentration?

A Electrical Conductivity (EC)
B Sodium Adsorption Ratio (SAR) of the soil solution
C Base Saturation Percentage
D Exchangeable Sodium Percentage (ESP)
E Cation Exchange Capacity (CEC)
