However, the precise relationships between soil properties and microbial diversity are poorly known. Here, we study the effect of agricultural management on soil microbial diversity and C turnover in tropical grassland of north-eastern Laos. Three years after native grassland conversion into agricultural land, we compared soils from five land use management systems: one till versus two no-till rotational cropping systems, one no-till improved pasture and the natural grassland. Soils were incubated in microcosms during 64 days at optimum temperature and humidity. Bacterial and fungal diversity were evaluated by metagenomic 454-pyrosequencing of 16S and 18SrRNA genes, respectively. Changes in soil respiration patterns were evaluated by monitoring 12C- and 13C-CO2 release after soil amendment with 13C-labelled wheat residues. Results show that residue mineralization increased with bacterial richness and diversity in the tilled treatment 7 days after soil amendment. Native soil organic C mineralization and priming effect increased with fungal richness and diversity in improved pasture and natural grassland. No-till cropping systems represented intermediate situations between tillage and pasture systems. Our findings evidence the potential of controlling soil microbial diversity by agricultural practices to improve soil biological properties. We suggest the promotion of no-till systems as a fair compromise between the need for agriculture intensification and soil ecological processes preservation.", "keywords": ["P33 - Chimie et physique du sol", "cycle du carbone", "Microbial diversity", "Conservation agriculture", "F08 - Syst\u00e8mes et modes de culture", "agro\u00e9cologie", "http://aims.fao.org/aos/agrovoc/c_7172", "[SDV.SA.SDS]Life Sciences [q-bio]/Agricultural sciences/Soil study", "630", "Tillage", "biodiversit\u00e9", "labour", "Acid savannah", "http://aims.fao.org/aos/agrovoc/c_12076", "biologie du sol", "http://aims.fao.org/aos/agrovoc/c_33990", "http://aims.fao.org/aos/agrovoc/c_2018", "sol acide", "Priming effect", "savane", "[SDV.SA.SDS] Life Sciences [q-bio]/Agricultural sciences/Soil study", "http://aims.fao.org/aos/agrovoc/c_6154", "pratique culturale", "http://aims.fao.org/aos/agrovoc/c_8511", "F07 - Fa\u00e7ons culturales", "2.

Results showed that application of sufficient slaked lime to initially increase the pH of the topsoil by 1 unit caused an increase in pH to 5 cm deeper than the layer of application as a result of bicarbonate leaching. With leaching of Ca from slaked lime or gypsum from the topsoil to the subsoil there was a decrease in exchangeable Al in the subsoil. Surface application of slaked lime or gypsum or both decreased the activity of toxic Al and increased AlSO4+ activity in the subsoil solution. The Ca added in slaked lime or gypsum was accounted for by the increase in exchangeable Ca over the soil profile and the leaching loss. By contrast there was a negative balance of extractable sulfate and aluminum in the soil, indicating the formation of precipitates. There was little mineralisation of N and formation of NO3- under the conditions of the experiment. The leaching of cations in this soil treated with slaked lime or gypsum was driven by the dynamics of sulfate.", "keywords": ["P33 - Chimie et physique du sol", "propri\u00e9t\u00e9 physicochimique du sol", "calcium", "lessivage du sol", "aluminium", "http://aims.fao.org/aos/agrovoc/c_7182", "http://aims.fao.org/aos/agrovoc/c_15591", "http://aims.fao.org/aos/agrovoc/c_200", "sulfate", "http://aims.fao.org/aos/agrovoc/c_317", "http://aims.fao.org/aos/agrovoc/c_1196", "gypse", "hydroxyde de calcium", "http://aims.fao.org/aos/agrovoc/c_1556", "sol acide", "min\u00e9ralisation", "http://aims.fao.org/aos/agrovoc/c_89", "http://aims.fao.org/aos/agrovoc/c_15999", "http://aims.fao.org/aos/agrovoc/c_1200", "amendement calcique", "http://aims.fao.org/aos/agrovoc/c_3453", "http://aims.fao.org/aos/agrovoc/c_7510", "F04 - Fertilisation"], "contacts": [{"organization": "Sun, B., Poss, Roland, Moreau, Roland, Aventurier, Alain, Fallavier, Paul,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.1023/a:1009870308097"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Nutrient%20Cycling%20in%20Agroecosystems", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1023/a:1009870308097", "name": "item", "description": "10.1023/a:1009870308097", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1023/a:1009870308097"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2000-01-01T00:00:00Z"}}], "links": [{"rel": "self", "type": "application/geo+json", "title": "This document as GeoJSON", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=sol+acide&f=json", "hreflang": "en-US"}, {"rel": "alternate", "type": "text/html", "title": "This document as HTML", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=sol+acide&f=html", "hreflang": "en-US"}, {"rel": "collection", "type": "application/json", "title": "Collection URL", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main", "hreflang": "en-US"}, {"type": "application/geo+json", "rel": "first", "title": "items (first)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=sol+acide&", "hreflang": "en-US"}, {"rel": "last", "type": "application/geo+json", "title": "items (last)", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items?keywords=sol+acide&offset=2", "hreflang": "en-US"}], "numberMatched": 2, "numberReturned": 2, "distributedFeatures": [], "timeStamp": "2026-07-26T13:10:20.246728Z"}
