“…The increasing SUVA 280 value in both compost piles during composting indicates increased amounts of water‐extractable aromatic compounds, resulting in significant enhancement of the stability of DOM in compost (Santos et al, 2012). During the biodegradation of composting materials, hydroxyl, carbonyl, and carboxyl groups on the aromatic rings were produced, which resulted in an increase in the E 253 /E 203 ratio (Morán Vieyra et al, 2009; Mouloubou et al, 2016). The variation in the SUVA 280 and E 253 /E 203 indicated that the degree of humification of the DOM is enhanced during composting.…”

This study investigated the degree of humification of dissolved organic matter (DOM) during different periods of cattle manure composting using ultraviolet-visible (UV-vis) and fluorescence spectroscopy (emission, synchronous scan, and excitation-emission matrix) and determined which method is more suitable for analysis of the humification degree of DOM. Two composting piles were prepared by mixing manure and corn straw. One pile (Pile A [PA]) contained inoculated exogenous composite agents at a ratio of 2% (v/v), and a pile without the addition of inoculants (PNA) served as the control treatment. The results showed that ultraviolet integrated absorption intensities in the range of 226 to 400 nm and 260 to 280 nm and specific ultraviolet absorbances at 254 and 280 nm of both PA and PNA gradually increased with composting time. Based on the fluorescence regional integration analysis and parallel factor analysis, the humic-like substances became the main components of the DOM after composting. Our study demonstrated that the humification degree of DOM was enhanced during composting and that the inoculation composite agent was beneficial for the humification of DOM at the mesophilic and thermophilic phases of the composting process. Moreover, the results of correlation analysis and principal component analysis demonstrated that the fluorescence spectral parameters evaluated the humification degree of DOM during the whole cattle manure composting process better than the UV-vis spectral parameters.

“…Waldrip et al [24] used UV-vis analysis to study WEOM in beef feed yard manure samples, where large differences in molecular weight, lignin content, and proportion of humified organic matter between manures from different sources were found. Mouloubou et al [25] used spectroscopic techniques to investigate changes of WEOM and pyrophosphate-extracted organic matter (OM) after annual compost amendment. In this study, rapid quantitative and qualitative changes were noted in both WEOM and pyrophosphate-extractable OM after compost application, primarily during the first 3 months after application.…”

Water extractable organic carbon (WEOC) and nitrogen (WEON) are two key parameters of soil water extractable organic matter (WEOM). Proper management of manure application rate in combination with tillage and cropping management could maintain appropriate WEOC and WEON concentrations in soils while decreasing the risk of their runoff from cropland and pastures. The objective of this research was to determine the effect of poultry litter (PL) application on WEOC and WEON in soils under different crops, tillage regimes, and grazing strategies. From 2001 to 2012, PL was applied at multiple rates to cultivated fields in a corn-oat/wheat-hay rotation or to pastures grazed by cattle or ungrazed. Soil samples (0 -15 cm) were analyzed for KCl-extractable mineral N, and WEOC, and WEON contents. In addition, Ultraviolet-visible (UV-vis) and fluorescence spectroscopies were used to characterize WEOC stability. Organic N levels were higher at the high PL application rates. The soil C:N ratio narrowed as the PL application rate increased. However, the soil from pastures which received PL tended to have a wider range of C:N ratios than soil from the cultivated fields, despite identical PL application rates. The spectral analyses indicated that WEOC properties were responsive to management and PL application rate; therefore, this parameter may be used as a guide to provide best management strategy for manure application.

In order to increase organic matter availability, date palm waste was co-composted with goat manure according to an industrial ecological approach for a sustainable development. During the composting process, the organic matter biodegradation and compost quality were controlled using physico-chemical and biological parameters associated to spectroscopic techniques. To promote the composting process, date palm waste was previously water soaked in basin for 5 days and the resulted wastewater was used to humidify the windrow. The results showed a rapid temperature increase during the first 6 days and a relatively long compost maturity phase. Organic matter content was reduced by 36% and C/N ratio shifted from 60 to 20 at the process end that held 6 months. The microbial activity and the germination index exceeding 80% indicated respectively the compost stability and its phytotoxicity lack. UV-visible spectra confirmed the organic matter biodegradation by the SUVA 254 , SUVA 269 and SUVA 280 values increase. During the process, the fourier transform infrared spectroscopy (FTIR) analysis of the different collected samples showed qualitatively similar spectra differing in the absorbance bands intensity, proving the organic matter 1 biodegradation and mineralization. A total of 12 fluorescence excitation emission matrixces of composts were successfully decomposed into a four-factor model using PARAFAC analysis. For the 4 main evidenced components, the excitation/emission (Ex/Em) wavelengths were of 350/450 nm, 400/500 nm 450/530 nm and 325/400 nm attributable respectively to humic-like and fulvic-like substances.
