Calculations•
meg/L = (ABSs- ABSBK) x dilution x concentration of standard
(ABSS3D - ~SBK) x meg weight
Sodium Absorption Ratio (SAR)
SAR = [Na+] _ (Ca#] + [Mgt]
2
Potassium Absorption Ratio (PAR)
PAR = [K+] [Ca {J + [Mgt]
2
• Where concentration values are in meg/L
Exchangable Sodium Percentage (ESP)
ESP = (-0.0126 = 0.01475A) x 100
1 + (-0.0126 + O.O1475A)
Where A = SAR
