| Sumario: | Soil microorganisms play an important role in the agroecosystem processes being affected by\nthe different crop management strategies applied in crop production. The effects of the\napplication of chemical fertilizers and inoculants formulated with plant growth promoting bacteria\nunder field conditions on native microbial communities are still unknown. The general objective of\nthis work was to generate knowledge about rhizosphere microbial ecology and agronomic\nvariables of wheat and corn when chemical fertilizers and Azospirillum brasilense inoculants are\napplied under field conditions. For that purpose, independent experiments for each crop were\nconducted in different production facilities located in the province of Buenos Aires, Argentina\nduring several agricultural seasons. Agronomic and microbiological variables were determined.\nThe results obtained in this work constitute a significant contribution to scientific knowledge, with\nthe aim of improving the inoculation responses in interaction with chemical fertilizer applications\nand characterizing the environmental risk of both agricultural practices. The results obtained\nunder this thesis have academic, productive and environmental implications and are directly\ntransferable to both consultants and farmers, in accordance with the current paradigm to favor a\nsustainable agricultural production. |
