Comparison of Various Methods of Sampling Soil Water for Determining Ionic Salts, Sodium, and Calcium Content in Soil Columns
1979
Barbarick, K. A. | Sabey, B. R. | Klute, A.
At the end of a column experiment studying the flux of ionic salts and Na⁺ from applied sewage effluent, the salt, Na⁺, and Ca²⁺ contents were compared in extracts from porous cups, from the soils around the cups, and saturated paste extracts after the column soils were air-dried. The salt level in the porous cup samples and in the moist soil samples obtained directly at the end of the experiment, and the Na⁺ content in the porous cup and in saturated paste extracts that were equilibrated for 48 hours were highly correlated.
