Abstract:
... Soil samples were collected from field experiments so as to obtain a range in (Ca + Mg) saturation and pH for each soil type. The effects of equilibrating media were studied by comparing water and 0.01M CaCl₂, each at 0.0003 and 0.0108 atm. partial pressure of CO₂. Linear relationships were found for pH − ½ p(Ca + Mg) in the equilibrium solution vs. (Ca + Mg) saturation of the samples. Correlation ...
