Extractable Al and Soil Solution Ionic Concentrations in Strongly Leached Soils from Northwest Iberia: Effects of Liming
Table 5
Total concentration of calcium (Ca+2), magnesium (Mg+2), potassium (K+), and sodium (Na+) ions in unlimed (control) and limed studied soil solutions as determined by inductively coupled plasma atomic emission spectrometry. Means in the same horizon followed by different letters in column are significant at by the Tukey test.
