“…Jiang et al (2021) conducted a life cycle assessment of wheat production and stated that the environmental impacts of wheat production greatly improved in the manure compost strategy [32]. In addition, some research showed that compost application has many environmental benefits for improving soil quality and reducing negative environmental impact, including increasing the level of carbon storage capacity in the soil; alleviating global warming; reducing the need for fertilizers, pesticides, and peat use; improving soil structure, density, and porosity; increasing water retention capacity; and reducing erosion and nutrient leaching [33][34][35]. The lower-case characters represent significant differences between strategies, while the same letters indicate no significant difference between strategies.…”

Wheat (Triticum aestivum L.) is a strategic agricultural crop that plays a significant role in maintaining national food security and sustainable economic development. Increasing technical performance considering lowering costs, energy, and environmental consequences are significant aims for wheat cultivation. For drylands, which cover approximately 41% of the world’s land surface, water stress has a considerable negative impact on crop output. The current study aimed to assess the environmental aspects of chemical fertilizer in combination with compost in dryland and irrigated winter wheat production systems through life cycle assessment (LCA). The cradle-to-farm gate was considered as the system boundary based on one tone of wheat yield and four strategies: D-C (dryland with compost), D (dryland without compost), I-C (irrigated with compost), and I (irrigated without compost). Based on the results, the highest and lowest amounts of wheat yield were related to the I-C and D strategies with 12.2 and 6.7 ton ha−1, respectively. The LCA result showed that the I strategy in comparison with other strategies had the highest negative impact on human health (49%), resources (59%), ecosystem quality (44%), and climate change (43%). However, the D-C strategy resulted in the lowest adverse effect of 6% on human health, 1% on resources, 10% on ecosystem quality, and 11% on climate change. Utilizing a combination of fertilizer and compost in dryland areas could ensure a higher yield of crops in addition to alleviating negative environmental indicators.

“…Therefore, improving the composting microenvironment and promoting microbial anabolism are important for improving the quality of the HSs during composting fermentation [112]. The addition of iron salts enhances the synergistic quinone oxidation-reduction cycle of iron reduction and promotes FR formation during humification in composting [113].…”

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

In recent years, alkali activation for potassium persulfate (PS) treatment has been proven a promising method in the advanced oxidation processes. However, the majority of studies have focused on water pollution control and remediation processes. There are few reports on the application of PS to transform organic solid waste into a resource. In this study, the sugarcane filter cake (SFC) was treated with PS activated by calcium hydroxide (CH) to convert it into an organic fertilizer (CH-PS/ SFC) with high amounts of fulvic-like acid (FLA). CH-PS/SFC could also be used to remediate the acid soil and immobilize heavy metals (HMs). Due to the simple structure and high sucrose content of SFC, the sucrosesaturated solution was to investigate the CH-PS treatment and the result was the production of a large amount of (785.7 mg/g) after 2 h. In optimal conditions, the yield of FLA in CH-PS/SFC could reach 316.8 mg/g, and the subsequent use as a fertilizer offered a germination index of over 80% and a decrease in the leachability of HMs. In addition, in the humification the maximum temperature was found to be 80.3 °C and the moisture decreased by 20% during the humification of SFC. Furthermore, pot experiments showed that CH-PS/SFC could promote Chinese cabbage growth, decrease the yellow leaves rate, and decrease the absorption of HMs by Chinese cabbage.
