Changes in the bacterial community structure in soil under conventional and conservation practices throughout a complete maize (Zea mays L.) crop cycle

Agricultural practices and changes in soil conditions, such as water content, inorganic N content, temperature, pH and organic material availability, affect the bacterial community structure. Soil characteristics and the bacterial community structure were monitored in soil with maize (Zea mays L.) a...

Soil characteristics and the bacterial community structure were monitored in soil with maize (Zea mays L.) and wheat (Triticum aestivum L.) rotation, zero tillage and crop residue kept (ZTRK) or removed (ZTRR), and conventional tillage with monoculture maize (CTMR) or maize-wheat rotation and crop residue removed (CTRR) or kept in the field and ploughed in (CTRK).

The bacterial community structure showed large changes over the crop cycle determined by varying soil characteristics, most importantly water content and NO3− concentration and six bacterial genera, i.e. Achromobacter, Bacillus, Halomonas, Kaistobacter, Pseudomonas and Serratia, while changes due to agricultural practices were much smaller. It was found that the bacterial community structure was affected significantly by time, tillage (zero tillage versus conventional tillage), crop residue management (kept versus removed) and crop rotation (CTMR versus CTRR treatment).Elsevier2020-08-25T00:30:17Z2020-08-25T00:30:17Z2021Published Versioninfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlePDFapplication/pdf0929-1393 (Print)https://hdl.handle.net/10883/2093510.1016/j.apsoil.2020.103733art. 103733157Applied Soil Ecologyreponame:Repositorio Institucional de Publicaciones Multimedia del CIMMYTinstname:Centro Internacional de Mejoramiento de Maíz y Trigoinstacron:CIMMYTEnglishAmsterdam (Netherlands)CIMMYT manages Intellectual Assets as International Public Goods.
