Resumo: | Animal manures are frequently utilized in agriculture as a source of nutrients, especially nitrogen (N). The objective of this work was to evaluate how the application of manure from different animal breeding systems during twelve years and 19 applications interferes in the soil solution dynamics and forms, as well as in the physiological and physiological state of maize plants. The study was conducted in an experiment conducted from 2004 to 2017 in Santa Maria, Rio Grande do Sul, Brazil. The treatments consisted in the application of swine slurry (DLS), cattle slurry (DLB), swine deep-litter bedding (CSS), mineral fertilization (NPK), Control, without application of nutrients. The determination of the concentrations of inorganic N (NID) (NO3 - +NH4 +) and organic N (NOD) dissolved in the soil solution was performed in situ by means of voltage lysimeters, prior to sowing and application of treatments (time 0) and at 5, 20, 35, 55, 80, 120 days after emergence of the culture (DAE). At these same times, plants were collected for evaluate the concentration of N in the tissue and the photosynthetic activity and the rate of transpiration were analyzed. N productivity and efficiency indexes for maize were also evaluated. The NID in the soil solution was the predominant N in all treatments, ranging from 53 to 80% of Total Dissolved Nitrogen (NDT). NPK was the only treatment that maintained high concentration of NO3 - in the soil solution up to 35 DAE and provided higher grain yield and physiological parameters favor and nutritional in maize plants. Among the organic sources, the use of DLB allowed greater grain yield and better indicators of physiological and nutritional parameters, but did not maintain availability of N in the solution of the soil adequate to the plants. |

O objetivo do trabalho foi avaliar como a aplicação de dejetos de diferentes sistemas de criação de animais, durante doze anos e 19 aplicações, interfere na dinâmica e nas formas de N na solução do solo, bem como na produtividade e estado fisiológico das plantas de milho. O estudo foi realizado de 2004 a 2017 em Santa Maria, Rio Grande do Sul, Brasil. Os tratamentos consistiram na aplicação de dejeto líquido de suínos (DLS); dejeto líquido de bovinos (DLB); cama sobreposta de suínos (CSS); fertilizante mineral (NPK) e controle, sem aplicação de nutrientes. A determinação das concentrações de N inorgânico dissolvido (NID) (NO3 - +NH4 +) e N orgânico dissolvido (NOD) na solução do solo foram realizadas in situ por meio de lisímetros de tensão, antes da semeadura e aplicação dos tratamentos (tempo 0) e aos 5, 20, 35, 55, 80, 120 dias após a emergência da cultura (DAE). Nestas mesmas ocasiões foram coletadas plantas para avaliação da concentração de N no tecido e foram analisadas a atividade fotossintética e taxa de transpiração. Também foram avaliadas a produtividade e os índices de eficiência e recuperação do N pelo milho. O NID na solução do solo foi a forma de N predominante em todos os tratamentos, variando de 53 a 80 % do Nitrogênio Dissolvido Total (NDT). O NPK foi o único tratamento que manteve uma concentração elevada NO3 – na solução do solo até 35 DAE e isso proporcionou maior produtividade de grãos e favoreceu parâmetros fisiológicos e nutricionais nas plantas de milho. Dentre as fontes orgânicas, o uso do DLB foi a que permitiu maior produtividade de grãos e melhores indicadores de parâmetros fisiológicos e nutricionais, mas não manteve uma disponibilidade de N na solução do solo adequada às plantas.porUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em Ciência do SoloUFSMBrasilAgronomiaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessDejetos de animaisN orgânico dissolvidoN inorgânico dissolvidoFertilizante mineralPlantio diretoDissolved organic NAnimal manureDissolved inorganic NMineral fertilizerNo-tillageCNPQ::CIENCIAS AGRARIAS::AGRONOMIA::CIENCIA DO SOLONitrogênio na solução do solo e aspectos nutricionais e fisiológicos do milho cultivado após 12 anos sob fontes orgânicas e mineralNitrogen in soil solution and nutritional and physiological aspects of corn cultivated after 12 years under organic and mineral sourcesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCeretta, Carlos Albertohttp://lattes.cnpq.br/1397096103904161Silva, Leandro Souza dahttp://lattes.cnpq.br/2152888530643357Tiecher, Taleshttp://lattes.cnpq.br/7665378790484936http://lattes.cnpq.br/1081637753985272Marchezan, Carina500100100005600edcc236c-92e7-4bd6-b9e2-c3195c64a23a07980172-7a3e-4e27-80cf-0339734e4599429718e1-de80-4230-ac85-da17200798636d1dd5c6-b3cf-46ce-ba45-1bfface2b8d0reponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
