What Is Exchangeable Sodium Percentage - Web the exchangeable sodium percentage (esp) is the amount of na+ adsorbed on the surfaces of the soil particle as a proportion of the cec, while the sodium absorption ratio (sar) is the relative concentration of na+ to ca2+ and mg2+. This method requires the determination of cation exchange capacity (cec) and exchangeable sodium percentage (esp). Web the exchangeable sodium percentage (esp) for coastal soils is around 2.5% of the base saturation on average, and one shouldn't run into trouble until this percentage of exchangeable sodium gets in the range of 7 or 8%. Web exchangeable sodium percentage (esp) is used in the classification of saline and alkali soils or to determine if a sodium hazard exists. Web “exchangeable sodium percentage (esp)” is the relative amount of the sodium ion present on the soil surface, expressed as a percentage of the total cation exchange capacity (cec). Since the determination of cec is time consuming and expensive, a practical and satisfactory correlation between the sodium adsorption ratio (sar) and esp was.
