However, the impacts of legume-based rotation on cropping system productivity and carbon (C) emissions have not been thoroughly investigated. Here, a field experiment was conducted to examine the impacts of three cropping systems (peanut-wheat, soybean-wheat vs. maize-wheat rotation) and two fertilization treatments (with and without fertilization) on crop yield, C footprint (CF), and agricultural sustainability. Our findings revealed that legume inclusion resulted in a higher crop yield (+40 % on average) than maize-wheat, and the yield advantage was 80% higher without than with fertilization. This demonstrated the effectiveness of legumes in enhancing crop production under low-input conditions. Legume inclusion enhanced the annual net income by 2.8 times over maize-wheat under no fertilization, while income declined by 20 % under fertilization. Notably, compared to maize-wheat, the direct greenhouse gas (GHG) emissions under legume-wheat decreased by 43 %, while indirect GHG emissions showed no significant difference. Furthermore, legume inclusion mitigated soil C stock loss by 1579 (kg C ha⁻¹ yr⁻¹) under no fertilization and increased soil C stock by 3766 (kg C ha⁻¹ yr⁻¹) under fertilization, further reducing the CF (-31 %) and enhancing the agricultural sustainability (+86 %).

To achieve the study objective, an experiment was conducted in a barley growing seasons of 2020–2021 and 2021–2022 in Baghdad, Iraq, using sprinkler and flooding irrigation systems, as well as conservation (field cultivator) and conventional (moldboard plowing) tillage practices on two types of soil textures: silty clay and sandy clay. The results indicate that, RZWQM2 satisfactorily captures the combination effects of field practices on water-barley productivity in different soil textures. The behavior of soil water-nitrate dynamics, crop development, and water consumption presented a noticeable response to the combination of experimental factors. When sprinkler irrigation was utilized, sandy clay soil was more responsive to field practices than silty clay soil by about 6–12 %. The moldboard plowing practice increased crop development and yield by about 5–10 % compared to the field cultivator practice. The combination of sandy clay soil, sprinkler irrigation, and moldboard plowing yielded more satisfactory results of water use efficiency and crop productivity.

We investigated soil fungal communities and subcommunities in response to reduction of nitrogen fertilization (fertilization rates were 100 %, 75 %, 50 %, and 0 %, respectively), based on a four-year field plot simulation experiment combining high-throughput sequencing technology.

Our results showed that the nitrogen fertilization reduction decreased the diversity (Shannon index) and improved the stability of whole fungal communities. In addition, reduction in nitrogen fertilization leads to an improvement in soil pH (from 4.21 to 6.11) and a decrease in ammonium nitrogen and nitrate nitrogen (94.29 and 130.49 mg/kg, respectively), and abundant taxa showing higher sensitivity but less fluctuations in the breadth of the ecological niche to environmental changes.

Substituting chemical fertilizers with organic fertilizers is considered an effective strategy to mitigate secondary salinization, improve saline-alkali soils, and enhance crop yields. However, the specific effects and underlying mechanisms of reducing chemical fertilizer application in combination with organic fertilizers in saline-alkali conditions remain insufficiently understood. This study focuses on summer maize grown in coastal saline-alkali areas, employing various proportions of organic fertilizer substitution (10 %, 20 %, 30 %, 40 %) to identify an optimal application model. The findings reveal that the application of organic fertilizer as a partial substitute for chemical fertilizer directly alters the contents of alkali-hydrolyzed nitrogen, available phosphorus, available potassium, and soil quality water content in different layers, which in turn affects the total absorption of nitrogen, phosphorus, and potassium to varying degrees, thereby influencing the crop's grain yield and biomass yield. Compared to the conventional use of chemical fertilizers alone, the incorporation of organic fertilizers led to changes in grain yield and biomass yield, ranging from −13.14 % to 7.14 % and −4.86 % to −8.14 %, respectively. The soil contents of alkali-hydrolyzable nitrogen, available phosphorus, and quick-acting potassium changed by −8.30 % to 1.40 %, −13.19 % to –7.81 %, and −1.81 % to 8.42 %, respectively. Additionally, the total uptake of nitrogen, phosphorus, and potassium by maize varied by −10.03 % to 7.62 %, −10.95 % to –8.93 %, and −9.64 % to 21.95 %, respectively. Significant differences were observed in maize yield, soil nutrient levels, and plant nutrient utilization rates across the different proportions of organic fertilizer substitution. Notably, the highest maize yield was achieved when the substitution proportion was 30 %, suggesting this ratio as the optimal application model for maize production in the saline-alkali soils of the Yellow River Delta.

Consequently, it becomes imperative to explore effective strategies that promote the preservation and enhancement of SOC. Some promising practices to increase SOC are the use of double-cropping, conservation tillage, and reduced N fertilization. The aim of this study was to evaluate the combined effects of introducing a legume prior to maize, together with different tillage systems and mineral N fertilization rates on SOC and related fractions (particulate organic matter carbon, POM-C; mineral-associated organic matter carbon, Min-C; and permanganate-oxidizable organic carbon, POxC). Additionally, the study aimed to investigate enzymatic activities associated with the carbon cycle. The study compared monocropping maize (MC) versus legume-maize double-cropping (DC) with two tillage systems (conventional tillage, CT; no-tillage, NT), and three mineral N fertilization rates (zero, medium and high). The legumes employed were pea for grain (2019), vetch for green manure (2020), and vetch for forage (2021). The DC increased the SOC level by 10.6 % compared to the use of MC, with POM-C as the main fraction involved in this change. Thus, the employment of DC allowed for the maintenance of SOC levels, while the use of MC resulted in their reduction compared to the levels observed at the beginning of the experiment. NT exhibited higher values of SOC and its fractions POM-C and Min-C. These differences were observed only in the 0–10 cm depth layers. The use of NT enabled the maintenance of SOC compared to the initial studied period, while CT reduced SOC. The treatments with N fertilization achieved higher values of SOC and all the studied fractions compared to the unfertilized treatment. However, at the end of the experiment, it was found that the application of N fertilization, especially at high rates, led to a decrease in SOC. Additionally, it was observed that the employment of DC and NT increased the enzymatic activities of dehydrogenase and β-glucosidase. The results of this study indicate that the utilization of legume-maize DC, as well as the implementation of NT and reduced N fertilization, are useful strategies to maintain SOC levels and improving the biological quality of the soil under Mediterranean irrigated conditions.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":"249 ","pages":"Article 106496"},"PeriodicalIF":6.1,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focus Group Discussions (FGD) were conducted with farmers and agricultural extension officers to gain supplementary information. Results suggest that perception of reduction of production cost from SSMP outweighs perception of reduction of inputs use requirements (e.g., reduction of working hour at farm, chemical fertilizer use and irrigation water use) and beneficial impact of SSMP on soil properties (e.g., improving soil organic matter, reducing soil salinity and soil erosion). The former was confirmed as key factor influencing short-term and long-term future adoption decision of various SSMP. Farmers are likely to choose SSMP that are conducive to increase net benefit by minimizing production cost. Farmers from areas with different levels of climate stress vulnerability were observed to have different perceptions and behaviour towards SSMP’s future adoption. Organic fertilization, residue incorporation and crop rotation with legume were considered for future adoption by farmers in drought-prone Rajshahi district to combat site-specific problem of drought, while in flood-prone Sunamganj and salinity-affected Khulna districts, residue incorporation were perceived beneficial to address soil salinity and mitigate soil erosion.

Previous studies have primarily focused on the impact of climate change on the climate suitability for maize cultivation in Northeast China, with little consideration of how changes in soil moisture and temperature due to conservation tillage affect maize climate suitability. Moreover, there is a lack of targeted conservation tillage implementation strategies that consider the specific characteristics of different regions. Therefore, this study quantifies the impact of conservation tillage on soil moisture and temperature, using these factors as environmental variables.

The results indicate that: (1) Conservation tillage significantly impacts soil moisture and temperature. When straw coverage reaches 30 % to 95 %, soil moisture increases by 0.04–0.13 m³ /m³ , while soil temperature decreases by 0.15–0.46°C, thereby influencing the distribution of maize climate suitability.
