a) Suppose that 1 g of dry soil is mixed vigorously with 100 mL of 0.5 M ammonium acetate solution. The soil and water mixture is filtered to remove the soil. The concentrations of calcium, magnesium, potassium, and hydrogen ions in the filtrate are measured. The concentrations of the cations found in the extraction solution are as follows: Ca2+-25.8 μg/mL, Mg2 3.4 ug/mL, K -2.2 ug/mL. Calculate the CEC of the soil. This is the same problem from Discussion 2....

Soil testing laboratories usually estimate cation-exchange capacity (CEC) as the sum of Ca2", Mg, and K displaced during extractions with neutral, 1 N ammonium acetate (NH 0Ac), which are performed primarily to test for available K. The following data were thereby obtained for three contrasting soils, but have been reported as pounds per acre for each of the three elements, assuming the conventional weight of 2 million pounds for an acre of soil 6 inches deep.
