Resumo: | This research conducted in different ages of Eucalyptus saligna Sm. stands in the region of Guaíba - RS, had as objectives: to estimate and model the biomass production; to estimate the nutrients stock and calibrate a fertilization recommendation system of soil based on the nutritional balance. On the basis of the forest inventory, trees of medium diameter were collected and fractionated in leaf, branch, bark, wood and root. The accumulated litter was evaluated with sampling units of 1 m2. Samples of arboreal components and litter were collected to estimate the dry matter and nutritional content. The modeling of biomass correlated dendrometric variables with the biomass of components trees and the accumulated litter. The biomass per unit area was estimated through the product between the average dry matter of each component and the number of trees per hectare, and in the case of accumulated litter, based on area of sample units. The net primary productivity was calculated accounting for the successive increments of biomass above and below ground and litter fall. Nutrients stock was obtained through the product between the average biomass of each component and the average concentration of nutrients. The fertilization recommendation system of soil was established considering the demand of nutrients according to the expected productivity and the supply of nutrients in the soil. Considering the average of stands of different ages, the main components in biomass accumulation were: wood > root > bark > branch > leaf. In relative values, only wood showed increasing trend with age of stands. The net primary productivity in stands between 2 and 8 years of age was 40.3 Mg ha-1 year-1, and 80 % in the components above ground and 14 % below ground. For the average of stands, the stock of nutrients showed the following order of accumulation: wood > root > leaf > bark > branch; and for nutrients: Ca > N > K > Mg > P ~ S > Fe > Mn > B > Zn > Cu. The fertilization recommendation system for Eucalyptus saligna based on the nutritional balance was shown efficient in determining doses of fertilizers, estimating values increased with the reduction of soil fertility and the increase of production expected. Based on the fertilizer recommendation system was possible to establish the following order of probability of nutritional limitation productivity: P > K > N > Ca ~ Mg, in Eucalyptus saligna plantations. |

Tese (Doutorado em Recursos Florestais e Engenharia Florestal) - Universidade Federal de Santa Maria, Santa Maria, 2014.http://repositorio.ufsm.br/handle/1/3775This research conducted in different ages of Eucalyptus saligna Sm. stands in the region of Guaíba - RS, had as objectives: to estimate and model the biomass production; to estimate the nutrients stock and calibrate a fertilization recommendation system of soil based on the nutritional balance.

Com base no inventário florestal, árvores de diâmetro médio foram coletadas e fracionadas em folha, galho, casca do tronco, madeira do tronco e raiz. A serapilheira acumulada foi avaliada com unidades amostrais de 1 m2. Amostras dos componentes arbóreos e de serapilheira foram coletadas para estimativa da massa seca e da concentração de nutrientes. A modelagem de biomassa correlacionou variáveis dendrométricas com a biomassa dos componentes das árvores e a serapilheira acumulada. A biomassa por unidade de área foi estimada pelo produto entre a massa seca média de cada componente e o número de árvores por hectare, e no caso da serapilheira acumulada, em função da área das unidades amostrais. A produtividade primária líquida foi calculada contabilizando os sucessivos incrementos de biomassa acima e abaixo do solo e deposição de serapilheira. O estoque de nutrientes foi obtido pelo produto entre a biomassa média de cada componente e a concentração média de nutrientes. O sistema de recomendação de fertilização do solo foi estabelecido considerando a demanda de nutrientes em função da produtividade esperada e o suprimento de nutrientes no solo. Considerando a média dos povoamentos de diferentes idades, os principais componentes em acúmulo de biomassa foram: madeira do tronco > raiz > casca do tronco > galho > folha. Em valores relativos, somente a biomassa de madeira do tronco apresentou tendência crescente com a idade dos povoamentos. A produtividade primária líquida nos povoamentos entre 2 e 8 anos de idade foi de 40,3 Mg ha-1 ano-1, sendo 86 % nos componentes acima do solo e 14 % abaixo do solo. Para a média dos povoamentos, o estoque de nutrientes apresentou a seguinte ordem de acúmulo: madeira do tronco > raiz > folha > casca do tronco > galho; e para nutrientes: Ca > N > K > Mg > P ~ S > Fe > Mn > B > Zn > Cu. O sistema de recomendação de fertilização para Eucalyptus saligna com base no balanço nutricional se mostrou eficiente no estabelecimento das doses de fertilizantes, estimando valores crescentes com a redução da fertilidade do solo e o aumento da produção esperada. Com base no sistema de recomendação de fertilizantes foi possível estabelecer a seguinte ordem de probabilidade de limitação nutricional da produtividade: P > K > N > Ca ~ Mg, nos povoamentos de Eucalyptus saligna.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia FlorestalUFSMBRRecursos Florestais e Engenharia FlorestalProdução de biomassaNutrição florestalCiclagem de nutrientesSustentabilidade nutricionalBiomass productionForestry nutritionNutrient cyclingNutritional sustainabilityCNPQ::CIENCIAS AGRARIAS::RECURSOS FLORESTAIS E ENGENHARIA FLORESTALRecomendação de fertilizantes para Eucalyptus saligna Sm. com base no balanço nutricional na região de Guaíba - RSFertilizers recommendation for Eucalyptus saligna Sm. based on the nutritional balance in the region of Guaíba - RSinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisSchumacher, Mauro Valdirhttp://lattes.cnpq.br/4577505947479643Calil, Francine Neveshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4766083E8Vogel, Hamilton Luiz Munarihttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4772952J8Viera, Márciohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4715544U7Muller, Ivanorhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4718818H8http://lattes.cnpq.br/0993331969822312Witschoreck, Rudi50020000000340030030030030030030066a4f294-3de9-4e2f-a787-e09bce097e3bcf7c027c-6353-44ad-a8df-d38ddbdb783e9ae9b946-234d-476d-8591-1cc703bec633f37fdbcf-e704-42fe-9455-a3c52757a7d3512eb0e5-c07d-4a72-a1dc-e65cfc4a2e0e7ad280a4-70da-4d53-9fb0-80ef9b299e9cinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALWITSCHORECK, RUDI.pdfapplication/pdf2669151http://repositorio.ufsm.br/bitstream/1/3775/1/WITSCHORECK%2c%20RUDI.pdf26fa548631ed8e9c57b466b803375df1MD51TEXTWITSCHORECK, RUDI.pdf.txtWITSCHORECK, RUDI.pdf.txtExtracted texttext/plain154547http://repositorio.ufsm.br/bitstream/1/3775/2/WITSCHORECK%2c%20RUDI.pdf.txt51f1610dbf2738ec598e77e209cb73ddMD52THUMBNAILWITSCHORECK, RUDI.pdf.jpgWITSCHORECK, RUDI.pdf.jpgIM Thumbnailimage/jpeg4978http://repositorio.ufsm.br/bitstream/1/3775/3/WITSCHORECK%2c%20RUDI.pdf.jpg85f229afed54ab0e0722ca3e4a9750d6MD531/37752021-09-21 16:54:57.066oai:repositorio.ufsm.br:1/3775Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2021-09-21T19:54:57Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
