Resumo: | This work was conducted in a native grassland of the Pantanal, locally called "caronal" due to the dominance of Elyonurus muticus. The objectives were to evaluate the effect of annual burnings of "caronal" on the cumulative aerial biomass, aboveground net primary production (ANPP) of herbaceous communities and soil cover. Monthly data of cumulative aerial biomass were collected during two years in an area which was burned in September/95 and in August/96, and in another area which was free of burning. ANPP was estimated through differences between aerial live biomass gathered monthly. Annual burnings reduced cumulative aerial biomass about 36% in the first year and 50% in the second year. There was a tendency of reduction of cumulative aerial biomass with repetition of the burnings. The ANPP herbaceous communities in the areas free of burning and with burnings were 3,850 kg/ha and 4,980 kg/ha, in the first year, and 5,090 kg/ha and 2,880 kg/ha in the second, respectively. Thirty days after burning, the soil cover was about 30% and only four to six months after burning it was re-established as the area free of burning. |

Os objetivos foram avaliar o efeito da queima anual de caronal sobre a biomassa aérea acumulada, produção primária líquida da parte aérea (PPLA) do estrato herbáceo e cobertura do solo. Foram coletados dados mensais de biomassa aérea acumulada durante dois anos, em uma área com queima em set./95 e ago./96, e outra sem queima. A PPLA foi estimada através das diferenças de biomassa aérea viva coletada mensalmente. A queima reduziu a biomassa aérea acumulada em aproximadamente 36% no primeiro ano e 50% no segundo. Houve uma tendência de redução de biomassa acumulada com a repetição da queima. A PPLA do estrato herbáceo nas áreas sem queima e com queima foi 3.850 kg/ha e 4.980 kg/ha no primeiro ano, e 5.090 kg/ha e 2.880 kg/ha no segundo, respectivamente. A cobertura do solo 30 dias após a queima foi de aproximadamente 30%, e somente quatro a seis meses depois foi restabelecido o porcentual da área sem queima.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCardoso, Evaldo LuisCrispim, Sandra Mara AraújoRodrigues, Cristina Aparecida G.Júnior, Waldomiro Barioni2000-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5924Pesquisa Agropecuaria Brasileira; v.35, n.8, ago. 2000; 1501-1507Pesquisa Agropecuária Brasileira; v.35, n.8, ago. 2000; 1501-15071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5924/3028info:eu-repo/semantics/openAccess2014-08-19T19:02:06Zoai:ojs.seer.sct.embrapa.br:article/5924Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-19T19:02:06Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
