Extractable Al and Soil Solution Ionic Concentrations in Strongly Leached Soils from Northwest Iberia: Effects of Liming
Table 6
Total concentration of iron (Fe+3), aluminium (Al+3), manganese (Mn+2), zinc (Zn+2), sulfate (), and phosphate () ions (μM L−1) in unlimed (control) and limed studied soil solutions, as determined by inductively coupled plasma atomic emission spectrometry Symbol: DL: detection limit (Al+3 = 0.25, Mn+2 = 0.03, Zn+2 = 0.06, = 0.002, and = 0.006 μM L−1, resp.). Means in the same horizon followed by different letters in column are significant at by the Tukey test.
