| dc.description | The present essay makes a reference on the populations of biological nitrogen fixers in the production of the soybean crop in the Los Ríos area. Biological nitrogen fixation takes place in the root nodules. The nodules are the result of a perfect symbiotic relationship between the plant and the bacteria. The bacteria that are part of these root nodules are called rhizobia. The conclusions determine that to improve the availability of nitrogen, nitrogen-fixing microorganisms are used, within which two groups are distinguished: "symbiotic" microorganisms that fix nitrogen in association with plants, these microorganisms called rhizobia colonize and form nodules in the plant roots where gaseous nitrogen is reduced to ammonium; and the "asymbiotic" (or free-living) type microorganisms that provide the environment with nitrogenous compounds such as ammonium, used by plants and the symbiotic association of Nitrogen in soybean cultivation allow maintaining the sustainability of agricultural systems, benefiting, not only to crop yields, but also to the physical and chemical conditions of the cultivated soils. | es_ES |

| dc.description.abstract | El presente ensayo hace de referencia sobre las poblaciones de fijadores biológicos de nitrógeno en la producción del cultivo de soya en la zona de Los Ríos. La fijación biológica del nitrógeno se realiza en los nódulos radiculares. Los nódulos son el resultado de una perfecta relación de simbiosis entre la planta y las bacterias. Las bacterias que forman parte de estos nódulos radiculares se denominan rizobios. Las conclusiones determinan que para mejorar la disponibilidad del nitrógeno, se emplean microorganismos fijadores de nitrógeno, dentro de los que se distinguen dos grupos: los microorganismos "simbióticos" que fijan nitrógeno en asociación con plantas, estos microrganismos llamados rizobios colonizan y forman nódulos en las raíces de las plantas donde el nitrógeno gaseoso se reduce a amonio; y los microorganismos de tipo "asimbióticos" (o de vida libre) que proporcionan al medio compuestos nitrogenados como amonio, aprovechados por los vegetales y la asociación simbiótica de Nitrógeno en el cultivo de soya permiten mantener la sustentabilidad de los sistemas agrícolas, beneficiando, no sólo a los rendimientos del cultivo, sino también a las condiciones físico químicas de los suelos cultivados. | es_ES |
