Vanderhasselt, AdriaanSteinwidder, Laura KatharinaD'Hose, TommyCornelis, Wim2024The intensification of modern arable farming has brought on a steady increase of the risk of soil compaction, while simultaneously pushing the impact deeper into the soil profile. In the subsoil, outside the reach of regular tillage operation, it can become exceedingly difficult to deal with compacted layers. Commonly, farmers turn towards mechanical remediation strategies, like subsoiling, to deal with this issue. However, the numerous drawbacks that come with these operations have prompted the search for more sustainable alternatives, like bio-subsoilers, which are deep-rooting plant species with the capacity to penetrate compacted subsoil layers. This study aimed at investigating both mechanical and biological remediation strategies in a side-by-side comparison. The effectiveness of subsoiling and the use of two deep rooting (cover) crops (i.e. alfalfa and fodder radish) as remediation measures to alleviate subsoil compaction was assessed in terms of soil quality indicators, like penetration resistance, bulk density, porosity, plant available water capacity, air capacity and air permeability at 35 and 45 cm depth, and the above-and belowground growth of the main crop. In addition, a combination of both subsoiling and use of deep rooting (cover) crops was included to evaluate the potential role of the latter in protecting the mechanically loosened subsoil from recompaction. This complex comparison was done in three distinct maize-based fodder crop rotations (rotation 1: maize monoculture; rotation 2: maize/winter cereal rotation with fodder radish as cover crop after winter cereal; rotation 3: maize/winter cereal/alfalfa rotation). The study field (sandy loam soil) was selected based on the presence of a highly compacted layer at the interface between topsoil and subsoil (30-50 cm). The experiment demonstrated that subsoiling is an effective remedia-tion measure to disrupt heavily compacted layers in the upper-subsoil, at least in the short-term. The crop response was however highly variable and only positive when the opportunity of reaching the subsoil proved to be advantageous for the crop (i.e. dry season). Besides its high degree of variability between years, the effects also proved to be very short-lived under a standard arable fodder crop rotation. Including deep rooting (cover) crops, like fodder radish and alfalfa, and limiting the initial subsoil disruption helped to partially stabilize the disrupted subsoil and reduce recompaction. Fodder radish and alfalfa penetrated the compacted subsoil without previous disruption by subsoiling. However, this did not lead to a significant improvement of the measured soil physical parameters.application/pdfhttps://biblio.ugent.be/publication/01HQ106DNBNJM4FY3VEG3JEJAThttp://hdl.handle.net/1854/LU-01HQ106DNBNJM4FY3VEG3JEJAThttp://doi.org/10.1016/j.still.2023.105956https://biblio.ugent.be/publication/01HQ106DNBNJM4FY3VEG3JEJAT/file/01HQ108CATHAEYK20C52QPATBRengNo license (in copyright)info:eu-repo/semantics/restrictedAccessSOIL & TILLAGE RESEARCHISSN: 0167-1987ISSN: 1879-3444Agriculture and Food SciencesSubsoil compactionSubsoilingBio-subsoilersRecompactionCrop rotationFodder cropsROOT-GROWTHPENETRATION-RESISTANCEPHYSICAL-PROPERTIESDEEP TILLAGECOVER CROPSPREFERENTIAL FLOWVERTICAL STRESSPLANT-GROWTHBULK-DENSITYWATER-UPTAKEOpening up the subsoil : subsoiling and bio-subsoilers to remediate subsoil compaction in three fodder crop rotations on a sandy loam soiljournalArticleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionEcological restoration evaluation of afforestation in Gudao Oilfield based on multi-source remote sensing data

Li, XiunengLi, YongtaoWang, HongQin, ShuhongWang, XinYang, HanCornelis, Wim2023The growing petroleum industry poses significant ecological challenges, prompting an increased focus on ecological restoration projects in onshore oilfields. Current efforts focus on revegetation in deforested oilfields, while research remains limited on alternative ecological restoration strategies aimed at establishing new eco-systems in oilfields. This study employed multi-source remote sensing data from 1985 to 2022 to calculate a remote sensing-based ecological index (RSEI) and constructed an integrated forest health index (IFHI), in order to evaluate the ecological restoration effects in the Gudao shelterbelt of Shengli Oilfield in the Yellow River Delta, and investigated the impact of oil extraction by considering forest phenology. The RSEI of the shelterbelt showed an upward trend and reached a Good level of ecological environment quality from 1990 to 2003, but it declined after that, indicating the potential of RSEI to quickly assess ecological restoration effects and guide management at different stages. Comparing the restoration effects of different tree species, a Robinia pseudoacacia L. (RP) and Fraxinus velutina Torr. (FV) mixed forest demonstrated the greatest capacity to improve environ-mental quality, with the most years (25 years) of the Good and Excellent levels and the highest IFHI value (1.52). In contrast, Ulmus pumila L. (UP) and Sophora japonica L. (SJ) were unsuitable for mixed planting for ecological restoration. The study also found that monospecific RP forests within 30 m of oil wells were significantly impacted by oil extraction (P <= 0.05), necessitating tailored forest management. The research aims to serve as a reference for ecological restoration in global onshore oil production areas, particularly in delta regions and sparsely vegetated areas.application/pdfhttps://biblio.ugent.be/publication/01HQ10J5WCEQN79AKEF2Z23H6Mhttp://hdl.handle.net/1854/LU-01HQ10J5WCEQN79AKEF2Z23H6Mhttp://doi.org/10.1016/j.ecoleng.2023.107107https://biblio.ugent.be/publication/01HQ10J5WCEQN79AKEF2Z23H6M/file/01HQ10KMTM8CBVSW02F44HK9TGengNo license (in copyright)info:eu-repo/semantics/restrictedAccessECOLOGICAL ENGINEERINGISSN: 0925-8574ISSN: 1872-6992Earth and Environmental SciencesEcological evaluationOilfield ecological restorationForest managementRSEICHINAWATERTEMPERATUREINDEXVEGETATIONDIVERSITYINCREASESDELTASOILEcological restoration evaluation of afforestation in Gudao Oilfield based on multi-source remote sensing datajournalArticleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionUsing soil organic matter fractions as indicators of soil physical quality

Pulido Moncada, Mansonia AlejandraLozano, Z.Delgado, M.Dumon, MathijsVan Ranst, EricLobo, D.Gabriëls, DonaldCornelis, Wim2018The objective of this study was to evaluate the use of chemical and physical fractions of soil organic matter (SOM), rather than SOM per se, as indicators of soil physical quality (SPQ) based on their effect on aggregate stability (AS). Chemically extracted humic and fulvic acids (HA and FA) were used as chemical fractions, and heavy and light fractions (HF and LF) obtained by density separation as physical fractions. The analyses were conducted on medium-textured soils from tropical and temperate regions under cropland and pasture. Results show that soil organic carbon (SOC), SOM fractions and AS appear to be affected by land use regardless of the origin of the soils. A general separation of structurally stable and unstable soils between samples of large and small SOC content, respectively, was observed. SOM fractions did not show a better relationship with AS than SOC per se. In both geographical regions, soils under cropland showed the smallest content of SOC, HA and carbon concentration in LF and HF, and the largest HF/LF ratio (proportion of the HF and LF in percent by mass of bulk soil). With significant associations between AS and SOC content (0.79**), FA/SOC (r = -0.83**), HA/FA (r = 0.58**), carbon concentration of LF (r = 0.69**) and HF (r = 0.70**) and HF/LF ratio (r = 0.80**), cropland showed lowest AS. These associations indicate that SOM fractions provide information about differences in SOM quality in relation to AS and SPQ of soils from tropical and temperate regions under cropland and pasture.application/pdfhttps://biblio.ugent.be/publication/8562267http://hdl.handle.net/1854/LU-8562267http://doi.org/10.1111/sum.12414https://biblio.ugent.be/publication/8562267/file/8562268engNo license (in copyright)info:eu-repo/semantics/restrictedAccessSOIL USE AND MANAGEMENTISSN: 0266-0032ISSN: 1475-2743Earth and Environmental SciencesAggregate stabilitysoil qualitychemical and physical fractionsAGGREGATE STABILITYDENSITY FRACTIONSCOVER CROPSSIZEMINERALOGYTEXTUREMANAGEMENTEXTRACTIONTILLAGECARBONUsing soil organic matter fractions as indicators of soil physical qualityjournalArticleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion
