Increases With Bio-Char Additions", "description": "This study examines the potential, magnitude, and causes of enhanced biological N2 fixation (BNF) by common beans (Phaseolus vulgaris L.) through bio-char additions (charcoal, biomass-derived black carbon). Bio-char was added at 0, 30, 60, and 90 g kg\u22121 soil, and BNF was determined using the isotope dilution method after adding 15N-enriched ammonium sulfate to a Typic Haplustox cropped to a potentially nodulating bean variety (CIAT BAT 477) in comparison to its non-nodulating isoline (BAT 477NN), both inoculated with effective Rhizobium strains. The proportion of fixed N increased from 50% without bio-char additions to 72% with 90 g kg\u22121 bio-char added. While total N derived from the atmosphere (NdfA) significantly increased by 49 and 78% with 30 and 60 g kg\u22121 bio-char added to soil, respectively, NdfA decreased to 30% above the control with 90 g kg\u22121 due to low total biomass production and N uptake. The primary reason for the higher BNF with bio-char additions was the greater B and Mo availability, whereas greater K, Ca, and P availability, as well as higher pH and lower N availability and Al saturation, may have contributed to a lesser extent. Enhanced mycorrhizal infections of roots were not found to contribute to better nutrient uptake and BNF. Bean yield increased by 46% and biomass production by 39% over the control at 90 and 60 g kg\u22121 bio-char, respectively. However, biomass production and total N uptake decreased when bio-char applications were increased to 90 g kg\u22121. Soil N uptake by N-fixing beans decreased by 14, 17, and 50% when 30, 60, and 90 g kg\u22121 bio-char were added to soil, whereas the C/N ratios increased from 16 to 23.7, 28, and 35, respectively. Results demonstrate the potential of bio-char applications to improve N input into agroecosystems while pointing out the needs for long-term field studies to better understand the effects of bio-char on BNF.", "keywords": ["2.

Evidence suggests that biochar can also increase crop yields, reduce nutrient leaching and increase biological nitrogen fixation in leguminous plants. However, the potential for increasing biological N2 fixation in agroecosystems is poorly understood, with inconsistent reports of root nodulation following biochar application. Therefore, the aim of this study was to determine the effect of biochar application rate and time since application on nodulation and nitrogenase activity in nodules of clover grown in a temperate agricultural soil. Methods: We used replicated field plots with three biochar application rates (0, 25 and 50 t ha-1). Three years after biochar amendment, the plots were further split and fresh biochar added at two different rates (25 and 50 t ha-1) resulting in double-loaded reapplications of 25&thinsp;+&thinsp;25 and 50&thinsp;+&thinsp;50 t ha-1. Results: Three years after biochar application, there was no significant difference in the total number of root nodules between biochar-amended and unamended soil, regardless of the application rate. However, despite clover root nodules being of a similar number and size the level of nitrogenase activity of individual nodules in biochar-amended soil was significantly higher than in unamended soil. Reapplication of biochar resulted in decreased nodulation, although the rate of nitrogenase activity per nodule remained unaffected. Conclusion: In the short term, biochar influences root nodule number and localised N2 fixation per nodule; however, total nitrogenase activity for the whole root system remained unaffected by the application rate of biochar or time since its application. These results emphasise the importance of long-term field studies, with a variety of applications rates for determining the influence of biochar applications on N2-fixing organisms and in providing data that can meaningfully inform agronomic management decisions and climate change mitigation strategies.", "keywords": ["Carbon sequestration", "2.

Data was collected for 20 morphological traits related to grain yields, nitrogen fixation and plant growth.\n\nResearch domain: Plant Breeding\n\nResearch question: How related are the cowpeas grown in Cameroon based on amount of nitrogen fixed and grain yield?.", "formats": [{"name": "CSV"}], "keywords": ["Soil", "biological nitrogen fixation", "cowpeas", "total phosphorus", "phylogeny", "opendata", "Boden"], "contacts": [{"name": "Maureen Fonji, Atemkeng", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": null, "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "atemkeng@zalf.de"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": "Germany"}], "links": [{"href": null}]}, {"name": "ZALF", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": "Research Platform 'Data Analysis & Simulation' - WG Geodata", "roles": ["publisher"], "phones": [{"value": "+49 33432 82 171"}], "emails": [{"value": "bonares-datenzentrum@zalf.de"}], "addresses": [{"deliveryPoint": ["Eberswalder Strasse 84"], "city": "M\u00fcncheberg", "administrativeArea": "Brandenburg", "postalCode": "15374", "country": "Germany"}], "links": [{"href": null}]}, {"name": "Maureen Fonji, Atemkeng", "organization": "Leibniz Centre for Agricultural Landscape Research (ZALF)", "position": null, "roles": ["projectLeader"], "phones": [{"value": null}], "emails": [{"value": "atemkeng@zalf.de"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": "Germany"}], "links": [{"href": null}]}, {"name": "Tietchou  Cyrille, Yousseu,", "organization": "Faculty of Agronomy and Agricultural Sciences, University of Dschang", "position": null, "roles": ["author"], "phones": [{"value": null}], "emails": [{"value": "yousse@yahoo.fr"}], "addresses": [{"deliveryPoint": [null], "city": null, "administrativeArea": null, "postalCode": null, "country": "Cameroon"}], "links": [{"href": null}]}, {"organization": "Leibniz Centre for Agricultural Landscape Research (ZALF);Faculty of Agronomy and Agricultural Sciences, University of Dschang", "roles": ["contributor"]}]}, "links": [{"href": "https://maps.bonares.de/mapapps/resources/apps/bonares/index.html?lang=en&mid=bfd7a9b9-c317-4a50-ad0e-881e9d241e31", "rel": "download"}, {"href": "https://metadata.bonares.de:443/smartEditor/preview/Phenogram_of_50_cowpea_accessions_grown_in_low_P_soils.jpg", "name": "preview", "description": "Web image thumbnail (URL)", "protocol": "WWW:LINK-1.0-http--image-thumbnail", "rel": "preview"}, {"rel": "self", "type": "application/geo+json", "title": "bfd7a9b9-c317-4a50-ad0e-881e9d241e31", "name": "item", "description": "bfd7a9b9-c317-4a50-ad0e-881e9d241e31", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/bfd7a9b9-c317-4a50-ad0e-881e9d241e31"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2024-03-11T00:00:00Z"}}, {"id": "3e5ac979-3675-4652-818e-67b6f42f2c67", "type": "Feature", "geometry": null, "properties": {"themes": [{"concepts": [{"id": "farming"}], "scheme": "https://standards.iso.org/iso/19139/resources/gmxCodelists.xml#MD_TopicCategoryCode"}, {"concepts": [{"id": "Soil"}, {"id": "biological nitrogen fixation"}, {"id": "plant pathology"}], "scheme": "AGROVOC Multilingual agricultural thesaurus"}, {"concepts": [{"id": "opendata"}, {"id": "nifH"}, {"id": "Fusarium graminearum"}, {"id": "Fusarium tricinctum"}, {"id": "Verticillium longisporum"}, {"id": "Leptosphaeria maculans"}, {"id": "wheat"}, {"id": "barley"}, {"id": "oilseed rape"}], "scheme": "Individual"}, {"concepts": [{"id": "Boden"}, {"id": "Soil"}], "scheme": "GEMET - INSPIRE themes, version 1.0"}], "license": "CC BY", "rights": "Restrictions applied to assure the protection of privacy or intellectual property, and any special restrictions or limitations or warnings on using the resource or metadata.
