Description
Few nmr studies with whole soil have been successfully attempted. Solid-state sup(13)C nmr spectra were obtained for Bainsville clay loam, an orthic humic gleysol with 3 percent carbon, using the CPMAS technique (cross-polarization magic-angle spinning). Results for the whole soil were limited by poor signal/noise and lack of resolution, possibly due to line-broadening by iron. Better results were obtained by employing a < 50 μm fine-size fraction, and difference spectra techniques, allowing observation of added sup(13)C-labelled acetate, and its transformation during incubation
