Fig. 2 Spatial distribution of chloride leaching from the lysimeter bottom. The center of the lysimeter is at . Each grid point represents a measurement location. The flat areas in the corners are outside the lysimeter cylinder. Average leaching (28.1 mmol Cl^-) is indicated by the bold contour line. Cumulative leaching amounts in excess of the average have contour lines at multiples of 25 mmol Cl^-
