“…Furthermore, the amount of studied environmental impacts (AD, AC, EP, GWP, OLD, HT, FE, ME, TE, and PO) in the CT system was higher than that in the NT system. This is in concordance with several recent research studies conducted on other crops such as corn silage (Fathollahi et al, 2018 ), wheat (Wang & Dalal, 2015 ), wheat and maize (Fantin et al, 2017 ), or orchards such as vineyard grape (Bogunovic et al, 2020 ; Marques et al, 2020 ), olive (López-Vicente & Álvarez, 2018 ; Taguas et al, 2015 ), and citrus (Niu et al, 2021 ; Novara et al, 2019 ).…”

The intensification of specific land management operations (tillage, herbicide, etc.) is increasing land degradation and contributing to ecosystem pollution. Mulches can be a sustainable tool to counter these processes. This is particularly relevant for rural areas in low-income countries where agriculture is a vital sector. In this research, the environmental impact of different rates of wheat residues (no residues, 25, 50, 75, and 100%) in corn silage cultivation was evaluated using the life cycle assessment (LCA) method under conventional tillage (CT) and no-tillage (NT) systems in a semi-arid region in Karaj, Iran. Results showed that in both tillage systems, marine aquatic ecotoxicity (ME) and global warming potential (GWP) had the highest levels of pollution among the environmental impact indicators. In CT systems, the minimum (17,730.70 kg 1,4-dichlorobenzene (DB) eq.) and maximum (33,683.97 kg 1,4-DB eq.) amounts of ME were related to 0 and 100% wheat residue rates, respectively. Also, in the CT system, 0 and 100% wheat residue rates resulted in minimum (176.72 kg CO2 eq.) and maximum (324.95 kg CO2 eq.) amounts of GWP, respectively. However, in the NT system, the 100% wheat residue rate showed the minimum amounts of ME (11,442.39 kg 1,4-DB eq.) and GWP (120.21 kg CO2 eq.). Also, in the NT system, maximum amounts of ME (17,174 kg 1,4-DB eq.) and GWP (175.60 kg CO2 eq.) were observed with a zero wheat residue rate. On-farm emissions and nitrogen fertilizers were the two factors with the highest contribution to the degradation related to environmental parameters at all rates of wheat residues. Moreover, in the CT system, the number of environmental pollutants increased with the addition of a higher wheat residue rate, while in the NT system, increasing residue rates decreased the amount of environmental pollutants. In conclusion, this LCA demonstrates that the NT system with the full retention of wheat residues (100%) is a more environmentally sustainable practice for corn silage production. Therefore, it may be considered one of the most adequate management strategies in this region and similar semi-arid conditions. Further long-term research and considering more environmental impact categories are required to assess the real potential of crop residues and tillage management for sustainable corn silage production.

“…Therefore, human intervention can be appropriately increased to obtain good‐quality forest in the process of natural restoration (Li et al, 2018, 2019). In addition, the DOC in the OP contained more biologically resistant coloured, aromatic, humic substances (Liu et al, 2021; Wallage et al, 2006), and intensive erosion was also observed (Fang et al, 2017; Niu et al, 2021). Rapid expansion of OP in Three Gorges Reservoir Area may accelerate the losses of soil DOC, and increase the risk of water quality deterioration in the downstream waterbodies (Fang et al, 2017; Wallage et al, 2006).…”

Dissolved organic carbon (DOC) is the substrate for microbial activities and regulates the biogeochemical cycle of carbon. Considerable areas of croplands have been converted to secondary forest and economic plantation following the implementation of Grain-for-Green Program projects in China, markedly altering the quantity and quality of topsoil DOC. However, the extent and magnitude of these land use changes affecting soil DOC remain largely unclear. This study aimed to elucidate the effects of different land uses and soil depths on topsoil DOC quantity and quality. Soil samples were collected from secondary forest (SF), orchards/plantations (OP), and cropland (CL) at 0-5, 5-10, 10-15, and 15-20 cm soil depths, respectively, from a representative purple soil hillslope, Southwest China. Soil DOC concentration and related UV-visible absorbance characteristics were determined to assesss respectively the quantity and quality of DOC. Results showed that DOC concentration was 44% lower in the OP than in the SF and CL. Higher ratios of UV absorbance value at 254, 260, and 400 nm to DOC concentration (i.e., SUAV 254 , SUVA 260 , and C:C ratio), electronic conductivity (EC), cation exchange capacity (CEC), soil organic carbon (SOC), and total nitrogen (TN) concentration were found in the OP rather than in the SF and CL. The SUAV 254 , SUVA 260 , SOC, and TN concentration were the highest at 0-5 cm soil depth. DOC concentration showed negative relationships with most UV absorbance values, SUAV 254 , SUVA 260 , and C:C ratio. Soil EC, CEC, and pH were closely correlated with the DOC concentration and its UV-visible variables. Our results indicated that DOC was relatively richer in aromatic and humic substances in the OP, providing valuable information for sustainable ecological restoration and land use management.

“…In especially vulnerable climates, like those associated with the Mediterranean basin or arid and semiarid areas, soil losses by harvesting should be analyzed in addition to soil losses caused by rainfall or tillage (González‐Hidalgo et al, 2007; Maetens et al, 2012) and wind‐erosion (Fenta et al, 2020). This issue has not yet been adequately addressed in areas cultivated with other conventional crops such as olives (Taguas et al, 2015), vineyards (Rodrigo‐Comino, 2018), or citrus (Niu et al, 2021). The values obtained with this study are higher than with the olive, vineyards, and citrus researches.…”

Soil loss from root crops is an increasingly significant problem studied for some species, such as potatoes, sugar beets, carrots, celery, and onions. It reduces soil fertility and, subsequently, soil productivity. For leek (Allium porrum) and groundnut (Arachis hypogaea), however, there is little information to date. More research on this topic could help farmers reduce the process of soil degradation. In some countries, such as
