Description
HCO3.
This is a soil salinity test. This procedure quantifies bicarbonate (HCO3 1-) concentration in mmolc L-1 in a soil saturation paste. The concentration of bicarbonate affects the solubility of calcium, the ionic strength of the extract solution and is used to calculate the adjusted sodiuim adsorption ratio. The method detection limit is approximately 0.05 mmolc/L and is generally reproducible within ± 10%.
