Changes in Solution of Forest Soils with Waterlogging and Three Levels of Base Saturation1
- William H. McKee2
Waterlogging and subsequent reduction significantly increased soil pH, except at high base saturation levels, for three Coastal Plain A horizon forest soils. When soils had high base levels, solution levels of Ca usually increased with soil reduction; Mg, Fe, and Mn levels increased with or without increase in base saturation. The effect of ion pairing was more proounced at low base saturation and on more weakly-charged colloid soils. The sharp increase in cation levels in the soil solution, caused by waterlogging and the influence of bicarbonate pairing, emphasizes the importance of the soil reduction in determining levels of nutrients available to trees on seasonally waterlogged soils.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
