Con el objetivo de evaluar diferencias en el uso del nitrógeno en pasturas asociadas con la leguminosa Leucaena diversifolia en el Valle del Cauca, Colombia, se evaluaron cuatro tratamientos de pasturas incluyendo Urochloa híbrido cv. Cayman y U. brizantha cv. Toledo solas y asociadas con L. diversifolia. Se midieron las variables de producción de biomasa, absorción de N en el forraje, fijación de N de L. diversifolia y las emisiones de óxido nitroso del suelo tras la aplicación de parches de orina en las pasturas. Los tratamientos de pasturas asociadas con L. diversifolia produjeron hasta un 165% más biomasa y presentaron hasta 50% mayor concentración de N en el tejido foliar que los tratamientos de Cayman y Toledo solos. Además, la proporción de N derivado de la atmósfera en L. diversifolia se estimó alrededor del 90%. Las emisiones de óxido nitroso absolutas tras la aplicación de parches de orina fueron mayores en las pasturas asociadas con L. diversifolia. No obstante, debido al aumento en la producción de forraje por unidad de área la intensidad de emisiones resultó hasta un 18% más baja que en las pasturas de gramínea sola. La integración de pastos de Urochloa con leguminosas como L. diversifolia constituyen una importante alternativa para intensificar sosteniblemente la producción animal de la mano con provisión de diferentes servicios ecosistémicos. (Texto tomado de la fuente)Cattle production in the tropics is carried out mainly on monoculture pastures, and is characterized by low adoption of technology and high land occupation. In order to evaluate differences in nitrogen use in pastures associated with the legume Leucaena diversifolia in Valle del Cauca, Colombia we evaluated four pasture treatments including Urochloa hybrid cv. Cayman and U. brizantha cv. Toledo both alone and associated with L. diversifolia. To that purpose we measured plant biomass production, forage N uptake, N fixation of L. diversifolia, and nitrous oxide emissions from soil after the application of urine patches in the pastures. Pasture treatments associated with L. diversifolia produced up to 165% more plant biomass and showed up to 50% higher N concentration in leaf tissue than the Cayman and Toledo alone pastures. Furthermore, the proportion of N derived from the atmosphere in L. diversifolia was estimated around 90%. Absolute nitrous oxide emissions after the application of urine patches were higher in pastures associated with L. diversifolia, however, due to the increase in forage production per unit area, the intensity of emissions was up to 18% lower than in grass alone pastures. The integration of Urochloa grasses with legumes such as L. diversifolia constitutes an important alternative to sustainably intensify animal production hand in hand with the provision of different ecosystem servicesMaestríaMagíster en Ciencias AgrariasCon el objetivo de evaluar diferencias en el uso del nitrógeno en pasturas asociadas con la leguminosa Leucaena diversifolia en el Valle del Cauca, Colombia, se evaluaron cuatro tratamientos de pasturas incluyendo Urochloa híbrido cv. Cayman y U. brizantha cv. Toledo solas y asociadas con L. diversifolia. Se midieron las variables de producción de biomasa, absorción de N en el forraje, fijación de N de L. diversifolia y las emisiones de óxido nitroso del suelo tras la aplicación de parches de orina en las pasturasSuelosxv, 61 páginasapplication/pdfspaUniversidad Nacional de ColombiaPalmira - Ciencias Agropecuarias - Maestría en Ciencias AgrariasFacultad de Ciencias AgropecuariasPalmira Valle del Cauca, ColombiaUniversidad Nacional de Colombia - Sede Palmira630 - Agricultura y tecnologías relacionadas::633 - Cultivos de campo y de plantaciónCultivos forrajerosForage cropsPastura y forrajePasture and forageNitrógenoNitrogenMolisolesMollisolsSueloSoilLeguminosas forrajerasFeed legumesBrachiariaCambio climáticoSilvopastorilClimate changeSilvopastoralUso del nitrógeno en pasturas asociadas con Leucaena diversifolia en un Molisol del Valle del Cauca, ColombiaNitrogen use in pastures associated with Leucaena diversifolia in a Molisol of Valle del Cauca, ColombiaTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMAdeniyi, I.
