Comparative effect of gypsum and limestone on drainage and salt removal from coastal alluvial soils of New Brunswick

Summary A drainage experiment with a tank model was conducted in the laboratory to evaluate the effect of gypsum and limestone on water movement and salt removal from recently flooded coastal alluvial soils. Equipotential lines, out-flow rates and the amount of sodium and chloride ions removed indicated that gypsum was a superior amendment to limestone.
