Lagoon water from cattle feedlot runoff was added to undisturbed soil columns 42 cm long and 6.7 cm in diameter. The infiltration rate of the lagoon water into the columns was measured and recorded. After each run, the soil columns were sectioned into 3‐cm increments and analyzed for Ca, Mg, Na, K, and NH 4 ions. Also the electrical conductivity of a saturation extract from the top 15 cm of each column was determined. Water flow in the soil columns stopped for all soils before two pore volumes of filtrate could be collected. Analyses for Ca, Mg, Na, K, and NH 4 showed that the percentages of Na, K, and NH 4 ions increased in the surface increments of the soil columns. The electrical conductivity of the saturation extracts for all soils was increased by more than 200% by adding the lagoon water to the soil. The saturation extract of the treated soils had electrical conductivity values of between 2.80 and 5.05 mmhos/cm.
