“…Yet, effects of adding carbon in the stable soil humic fractions in arid environments have only been slightly investigated. In fact, the most important factor affecting soil quality is soil humic compounds (Xu et al 2007). They enhance the life of N and P in soil, improve soil aggregates and stimulate plant respiration in soil (Hernandez et al 2001).…”

Purpose The most important factor affecting soil quality is soil humic fraction. Effects of adding carbon in soil humic compounds in arid environments have only been slightly investigated. The change in soil humic acids' structures in relation with manure and palm compost application and the evolution of humic acids' structures during palm composting have not been sufficiently investigated. The purpose of this study is to evaluate if date palm compost is suitable for the sustainable increase of soil carbon content with increasing soil humic compounds. Methods Soil was amended with date palm compost and sheep manure, which represented two treatments, in addition to a control represented by unamended soil. Soil samples were taken from depth layers of 0-20 cm and 20-40 cm. Physicochemical and spectroscopic analyses were used to study humic acids extracted from organic amendment and soil. Results The neutral pH and the C/N ratio of 11.9 revealed that the palm/manure compost was mature. Date palm compost application on soil showed its effectiveness in improving soil quality. Spectroscopic studies of humic compounds extracted from date palm compost and manure, showed the abundance of aromatic structures, confirmed by the low E4/E6 ratio associated with an increase in polycondensation and polymerization. Infrared spectroscopy of humic acids extracted from amended soil revealed its enrichment with aromatic structures. Conclusions Using date palm compost for a short term suggests that this compost may be useful as an alternative to increase the soil fertility by increasing the humic acids quantity with enhancing aromaticity degree and functional groups.

“…Many authors [18,24,25] have emphasized the importance of HWEOC transformations. The cited authors considered hot water extracted organic carbon as the most sensitive indicator reflecting changes in organic matter caused by different soil management practices between sites and within an ecosystem.…”

The valorization of sewage sludge (SS) has been presented originating from four wastewaters treated in wastewater treatment plants (WWTPs) located in the Wielkopolska province. In the SS samples collected in two successive years, the quantity and quality of humic substances (HSs), fulvic and humic acids (FAs, HAs), amounts of organic carbon (TOC), organic matter (OM), labile carbon (CL), and water extracted organic carbon (WEOC) were determined. It was investigated how the defined parameters depend on the size of the installation and select those which in a routine SS analysis facilitate rapid assessment of their quality and suitability for application in the natural environment. Regardless of WWTP size and the year of analysis, SS was characterized by a significant share of easily decomposable compounds such as FAs and WEOC. The statistical analysis showed significant usefulness of CL, FAs, and HAs in the evaluation of SS quality and usability.

“…The addition of sewage sludge increases the organic carbon content of the soil with possible positive consequences for SOC sequestration by chemical and physical stability (Roig et al, 2012) but there still exists a lack in SOC storage information to be more conclusive (Fernández et al, 2009;Haller et al, 2010;Roig et al, 2012;Kalisz et al, 2017; Table 54).…”

“…Excess application promotes the loss of nutrients through volatilization and/or lixiviation, for example increased emissions of CO2 emissions (Cattin et al, 2019;Haller et al, 2010;Kalisz et al, 2017), ammonia and nitrous oxide into the atmosphere Rigby and Smith, 2013).…”

Cover cropping (CC) can be applied worldwide, but there is not a cover crop that fits every farming situation and potential benefits vary with climate, soil type and plant species. In detail, CCs can better fit in humid and subhumid regions than in semiarid regions where precipitation is limited (Unger and Vigil, 1998). The possible competition of CCs for available soil water in semiarid regions can limit the adoption of the practice (Unger and Vigil, 1998;Nielsen et al., 2015). A different approach to agricultural management is required for arable and woody crops. Impact on soil organic carbon stocksThe C storage potential of CCs is quite variable at regional level and with land use, ranging from 0.27 to 1.03 tC/ha/yr in the examined meta-analyses (Table 1). A higher potential was found in woody crops in warm temperate dry climates (about 1.00 tC/ha/yr), and lower values in arable crops most for temperate and tropical climates (0.32-0.56 tC/ha/yr). C storage potential in arable systems was 0.71, 0.51 and 0.46 tC/ha/yr in tropical, temperate and arid climates respectively (Jian et al., 2020). Data from a literature review (Blanco-Canqui et al.
