The use of modern spectroscopic methods analysis, which provide extensive information on the chemical nature substances, significantly expands our understanding molecular composition and properties soil organic matter (SOM) its transformation stabilization processes in various ecosystems geochemical conditions. aim this review is to identify analyze studies related application nuclear magnetic resonance (NMR) electron paramagnetic (EPR) spectroscopy techniques study virgin arable soils. This article mainly based three research questions: (1) Which NMR are used SOM, what their disadvantages advantages? (2) How technique structure different pools SOM? (3) ESR SOM chemistry, advantages limitations? Relevant published between 1996 2024 were searched four databases: eLIBRARY, MDPI, ScienceDirect Springer. We excluded non-English-language articles, non-peer-reviewed articles other non-article publications, as well publications that not available according search protocols. Exclusion criteria for EPR non-SOM where these primary methods. Our scoping found both solid-state solution-state commonly (SOM). Solution-phase particularly useful studying soluble components a low weight, whereas solid-phase offers such higher 13C atom concentration stronger signals faster analysis time. However, solution-phase has limitations including sample insolubility, potential signal aggregation reduced sensitivity resolution. Solid-state better at detecting non-protonated carbon atoms identifying heterogeneous regions within structures. spectroscopy, hand, significant experimental biochemistry due high ability detailed about substances containing free radicals (FRs), aiding assessment reactivity transformations. Understanding FR biopolymers can help formation SOM. integration two- three-dimensional with analytical methods, chromatography, mass spectrometry, etc., provides more comprehensive approach deciphering complex than one-dimensional alone.

ABSTRACT Soil organic matter (SOM) was the primary component of global terrestrial carbon sink. enzymes were important drivers soil metabolism facilitating materials cycling and energy flow in soils. However, relationship between SOM composition various land use types had not been clearly understood. In current study, pyrolysis gas chromatography/mass spectrometry (Py‐GC/MS) used to analyze three (grassland, forest, cropland) enzyme activity upper watershed Danjiangkou Reservoir China. The C‐cycling glucosidase, cellobiose glycosidase, xylosidase, P‐cycling alkaline phosphatase, N‐cycling leucine aminopeptidase grassland highest but S‐cycling methylumbelliferryl sulfate potassium salt lowest grassland. forest. Aliphatic (23.1%–25.1%), N‐compounds (16.69%–21.17%), aromatic (11.76%–12.61%) most abundant components complexity molecular network forest highest. Additionally, all acetylglucosaminidase significantly positively related proportion polysaccharides negatively terpenoids. Our study emphasized that affected activities further revealed difference uses probably nitrogen‐containing compounds, polysaccharides, terpenoids SOM.

The accumulation of copper (Cu) and zinc (Zn) from piglet feed, coupled with inadequate compost maturation, hinders the safe land application pig manure (PM). This study employed self-organizing maps (SOMs) integrated three-dimensional excitation–emission matrix fluorescence spectroscopy (3D-EEM) parallel factor analysis (PARAFAC) to evaluate PM maturity Cu/Zn passivation under different biochar (BC) dosages (0%, 8%, 10%, 12%). results revealed that SOM clustering effectively distinguished composting phases organic matter transformation trends, while network identified key microbial modules (M5, M6) linked passivation. Moreover, 12% BC accelerated maximizing humic content (C1: anthropogenic; C4: terrestrial) by increasing Luteimonas abundance (241.98%) reducing Terrisporobacter (92%). It also achieved highest Cu (36.36%) Zn (32.34%) Although 10% promoted C4 synthesis but inhibited C1 formation, it ultimately reached a similar level BC. Additionally, demonstrated comparable (34.85%) (27.89%) passivation, making more cost-effective alternative. These findings highlight as robust tool for evaluation, optimizing improving efficiency.
