To address this concern, we conducted a series of studies from 2021 to 2023. Preliminary tests assessed the effects of the combined application of yeast and glucose on the porosity of compacted soil and on turfgrass growth under conditions of soil compaction. In subsequent dose screening studies, two-factor tests were performed to identify the best combination of yeast and glucose doses that enhance soil porosity and promote turfgrass growth under compaction stress. Therewith, we evaluated the effects of the identified best combination of yeast and glucose on plant growth and on physicochemical properties of shallow soil. It was found that the best dose for enhancing turfgrass growth in compacted soil was 200 g of yeast and 200 g of glucose per square meter. This combination significantly improved turf quality by 40 %, reduced soil bulk density by 9.11 %, and enhanced soil nutrition within 28 days. Additionally, notable enhancements in plant growth were observed in coastal saline-alkali lands and alpine meadows. The findings suggest that this innovative microbial-based approach could substantially improve plant growth under soil compaction stress. Furthermore, it proposes that investigating composite microbial inoculants, incorporating cellulose-degrading microbes, could concurrently address crop straw accumulation and extensive soil compaction.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":"247 ","pages":"Article 106380"},"PeriodicalIF":6.1,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722630","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}

However, the specific effect of different species and consortia of CCs on soil structure still needs to be well understood. In addition, the effect of seasonality on soil structure requires further investigation. Thus, this study aimed to report which species or consortia of CCs improve the structure and infiltration of water in the soil more broadly and whether seasonality influences the physical properties and the infiltration of water of the soil in a no-till area in southern Brazil. The experiment was conducted under a Psammentic Paleudult, involving six treatments: T1 - bare soil with maintenance of the surface crust (BS), as the control condition; T2 - permanent grasses (predominantly <em>Paspalum notatum</em>) (PG); T3 - black oats (<em>Avena strigosa</em>) + forage turnip (<em>Raphanus sativus</em>) in winter, followed by beans (<em>Phaseolus vulgaris</em>) or cowpea (<em>Vigna unguiculata</em>) in summer (OT/B); T4 - ryegrass (<em>Lolium multiflorum</em>) in winter, followed by black beans or pigeon pea (<em>Cajanus cajan</em>) in summer (Rg/B); T5 - black oats + vetch (<em>Vicia villosa</em>) in winter, followed by black beans or cowpea in summer (OV/B); and T6 - forage peanut (<em>Arachis pintoi</em>) (FP). In 2022, after six years of experiment (medium term), we evaluated soil bulk density and pore size distribution (0–5, 5–20, 20–40, and 40–60 cm layers), aggregate stability (0–10 cm layer), water infiltration (with double concentric ring and Cornell infiltrometer), soil moisture (continuous monitoring at a depth of 5 cm) and biomass input. Areas under the PG treatment presented high aggregate stability but decreased macroporosity (especially in 0–20 cm) and water infiltration compared to other treatments with CCs. The FP treatment provided the broadest and most evident benefits in soil structure. Treatments with annual cover crops, especially OT/B, had improvements in soil structure compared to the FP treatment. As biomass above and especially below ground level increased, physical properties improved. In summer, macroporosity was higher (in all layers) and soil moisture lower, which increased the steady infiltration rate by 377 % compared to winter. In conclusion, the species or consortia of CCs and seasonality influence the structure and infiltration of water in an Ultisol under no-till in southern Brazil, and the contribution of biomass from live plants is a major criterion to guide the choice of CCs with great capacity to conserve or regenerate the functionality of the soil structure.</div></div>","PeriodicalId":49503,"journal":{"name":"Soil & Tillage Research","volume":"247 ","pages":"Article 106366"},"PeriodicalIF":6.1,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142703039","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}

However, its effect on soil aggregation and organic carbon and nitrogen sequestration across soil textures remains unclear. In this systematic review, the results of 534 experiments reported in 100 peer-reviewed articles were analyzed. The results show that biochar addition enhances macroaggregate formation, improves aggregate water stability, and enriches organic carbon and nitrogen in different-sized aggregates compared with un-amended controls. When comparing clay and loam soils to biochar, clay soils respond more effectively to biochar than did loam soils. Specifically, the size distribution of clay aggregates responded to biochar input, whereas the organic carbon within different-sized aggregates of loam soil significantly increased. The benefits of biochar are attributed to the reduction in clay bulk density (−10.9 %) and the increase in microbial biomass carbon (+32.4 %), as well as enhanced organic matter input from plant biomass (+28.3 %) in loam. Long-term experiments (&gt; 3 yr) revealed more macroaggregate-associated organic carbon in both loam and clay soils. Based on the results of this assessment, the optimal application conditions of biochar in loam and clay soils are as follows: in loam soils with initial organic carbon levels of 5–10 g·kg⁻¹, biochar should be applied at a rate of 10–20 t·ha⁻¹ to maximize large macroaggregate formation; in clay soils, an application rate of 20–40 t·ha⁻¹ of biochar is recommended.

However, a comprehensive evaluation for the effects of organic fertilizer substitution on nitrate residue and leaching losses during the fallow season is not available in winter wheat-summer fallow rotation system. The present dryland wheat fertilization experiment conducted from 2014−2019 adopted a split-plot design, with manure dosage (i.e., M₀; NPK group and M₁; MNPK group) as the main plots and nitrogen fertilizer dosage as the subplot (i.e., N₀, N₇₅, N₁₅₀, N₂₂₅, N₃₀₀). In short, the peaks of NO₃⁻ in the 0−200 cm profile gradually move toward the deep soil layer with increasing years of fertilization, and the number of peaks also gradually increases. Increasing the N rate always leads to a sharp increase in nitrate residue in the 0−200 cm profile at the harvest stage (HNR) and sowing stage (SNR) and results in a large amount of nitrate leaching loss (ΔNR) during the summer fallow season, especially when the N rate was&gt; 150 kg ha⁻¹. Compared to NPK, MNPK significantly increased SNR and ΔNR by 38.1 % and 171 %, respectively, but decreased HNR by 36.2 %. ΔNR was positively related to fallow season precipitation and soil water storage changes during the fallow season in the 0–200 cm profile.

The average grain yield of MNPK was 13.9 % higher than that of NPK. Therefore, manure combined with 150 kg ha⁻¹ N fertilizer is the best fertilization strategy to ensure high productivity of dryland wheat, control nitrate residue, and reduce nitrate leaching loss during the summer fallow season.

The main objective of this study was field demonstration on the usefulness of fly ash-based WAP (FA-WAP) in prolonging wilting and plant survival time of beans (<em>Phaseolus vulgaris</em>) and radish (<em>Raphanus sativus</em>) in a silt loam. This was achieved by following a novel methodology for determining plant permanent wilting point (PWP) by integrating both soil response (suction) and plant response (stomatal conductance and photosynthetic yield), as against the common practice of considering a reference negative water potential (or soil suction) value of 1500 kPa. Using the proposed methodology, the PWP was 1300 kPa and 1150 kPa for beans and radish, respectively. The measured soil water retention curves (SWRC) demonstrated higher water availability in the WAP-amended soil compared to the control soil for both plant species, thereby prolonging plant survival time. The presence of WAP positively influenced the plant biochemical parameters (such as H₂O₂, MDA, proline, CHL A+B) under water deficit conditions. The WAP amendment resulted in 2.3 and 1.4 times crop yield for beans and radish, respectively, compared to the unamended soil.

Specifically, the application of NPK significantly reduced the connected porosity, accessibility, and network complexity within the macroaggregates, whereas the opposite effects were observed with the RS treatment. Connectivity analysis showed that the critical pores in CK, NPK, and RS+NPK treatments originated from plant roots, while those in the RS treatment were likely formed through the decomposition of rice straw. Compared to CK, the NPK treatment exhibited fewer channels with high hydraulic conductance, indicating impaired transportability of water and nutrients under saturated conditions, while the opposite was true for the RS treatments. Furthermore, skeleton analysis highlighted that the NPK treatment has fewer paths for preferential and capillary flow compared to CK, indicating reduced accessibility of air, water, and nutrients under unsaturated conditions.
