"Weborganic matter, the SMP solution is not an ideal method, since frequently the pH-SMP values are lower than the calibrated limit of most mineral soils. This suggests that the buffer capacity of the SMP solution is insufficient to counterbalance the high acidity of these soils, which is due to the several acid functional groups of the organic matter.
