Description
x-Mg.
This is a soil fertility test. This method quantitatively determines the concentration of exchangeable Magnesium in the soil saturation paste extract using atomic absorption spectrometry (AAS) or Inductively Coupled Plasma Emission Spectrometry (ICP-AES). The method detection limit is approximately 0.02 mmolc/L on a solution basis and it is generally reproducible within ± 7%.
