英文摘要Mineral binding is a major mechanism for soil carbon (C) stabilization. However, the submicron information about the in situ mechanisms of different fertilization practices affecting organo-mineral complexes and associated C preservation remains unclear. Here, we applied nano-scale secondary ion mass spectrometry (NanoSIMS), X-ray photoelectron spectroscopy (XPS), and X-ray absorption fine structure spectroscopy (XAFS) to examine differentiating effects of inorganic versus organic fertilization on interactions between highly reactive minerals and soil C preservation. To examine such interactions, soils and their extracted colloids were collected during a 24-year long-term fertilization period (1990-2014) (no fertilization, control; chemical nitrogen (N), phosphorus (P), and potassium (K) fertilization, NPK; and NPK plus swine manure fertilization, NPKM). The results for different fertilization conditions showed a ranked soil organic matter concentration with NPKM > aEuro-NPKaEuro-> aEuro-control. Meanwhile, oxalate-extracted Al (Al-o), Fe (Fe-o), short-range ordered Al (Al-xps), Fe (Fe-xps), and dissolved organic carbon (DOC) ranked with NPKM > aEuro-controlaEuro-> aEuro-NPK, but the ratios of DOCaEuro-a center dot aEuro-Al-xps and DOCaEuro-a center dot aEuro-Fe-xps ranked with NPKMaEuro-> aEuro-NPKaEuro-> aEuro-control. Compared with the NPK treatment, the NPKM treatment enhanced the C-binding loadings of Al and Fe minerals in soil colloids at the submicron scale. Furthermore, a greater concentration of highly reactive Al and Fe minerals was presented under NPKM than under NPK. Together, these submicron-scale findings suggest that both the reactive mineral species and their associations with C are differentially affected by 24-year long-term inorganic and organic fertilization.
