Abstract/Contents:"The cation exchange capacity (CEC) of soil samples submitted to commercial soil testing laboratories is often estimated by summation of the nonacid cations (CECsum) extracted in a routine soil nutrient analysis. These CEC estimates can predict measured CEC in non-calcareous soil samples but are inappropriate for use in calcareous soils and have not been evaluated in anthropogenic sand rootzones of turfgrass sites. In a dataset of 37 sand and 17 soil samples varying in pH, calcium carbonate equivalent (CCE), and organic matter (OM) content, we evaluated the ability of the summation method to predict measured CECCE (by compulsive exchange) using 5 extraction methods: 1 M NH4OAC, Mehlich 3, Morgan, 0.01 M SrCl2, and 1:5 H2O. The CECsum estimates based on 1 M NH4OAC, Mehlich 3, and Morgan extractions were inaccurate for the calcareous samples and overestimated CECCE in sands with CCE < 10 g kg-1. The CECsum based on the 1:5 H2O extraction underestimated CECCE in all soil types. Estimates based on the 0.01 M SrCl2 extraction were accurate in all sands and in soils with CECCE < 60 mmolc kg-1. In soils with CECCE > 60 mmolc kg-1, two consecutive extractions with 0.01 M SrCl2 and summation of nonacid cations extracted provided an accurate estimate of CECCE."
