Na.

This is a soil salinity test. This method determines the concentration of sodium in a soil saturation paste extract using Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Emission Spectrometry (ICP-AES). The method detection limit for these cations is approximately 0.02 mmolc/L on a solution basis and it is generally reproducible within ± 7%.
