Resumo: | The objective of this research was to determine changes in properties of a Red-Yellow Podzolic soil, related to the gradual removal of the plow layer through simulated erosion and its effects on survival and growth of Mimosa caesalpiniaefolia Benth seedlings. In 1990, the experiment was conducted in a greenhouse of the Universidade Federal do Ceará, in Fortaleza, CE, Brazil, in layers of 0-15, 5-20, 10-25, 15-30, 20-35 and 25-40 cm which were removed from a Red-Yellow Podzolic profile and contained in plastic bags where seeds were planted and seedlings were grown for 85 days. Higher values of clay percentage, available water, K and Ca contents and of CEC at deeper layers did not reduce the negative impact of erosion on the seedlings survival and growth since they were associated with increases of Al saturation as well as with significant decreases in pH, organic matter, base saturation and N, P and Mg contents in the soil. As depth of the removed layers increased, seedlings survival percentage, seedlings height, root and aerial part dry weights, as well as total dry biomass gradually decreased. Compared to the 0-15 cm layer, at 25-40 cm those decreases were 16.8, 66.3, 67.1, 82.0, and 79.6%, respectively. |

O experimento foi conduzido em casa de vegetação, em 1990, no Departamento de Ciência do Solo, UFC, em Fortaleza, CE, em camadas do solo de 0-15, 5-20, 10-25, 15-30, 20-35 e 25-40 cm, as quais foram removidas e acondicionadas em sacos de plástico, onde as sementes foram plantadas e as mudas desenvolveram-se por 85 dias. Maiores valores de porcentagem de argila, de água disponível, de teores de K e Ca e da CTC determinados nas camadas mais profundas não reduziram o impacto negativo da erosão na sobrevivência e crescimento das mudas, pois eles estavam associados a aumentos da saturação por Al, bem como a significativos decréscimos no pH, na matéria orgânica, na saturação por bases e nos teores de N, P e Mg no solo. À medida que a profundidade das camadas removidas aumentava, a porcentagem de sobrevivência, a altura, o peso seco das raízes e da parte aérea, bem como a biomassa seca total das plantas gradualmente decrescia; esses decréscimos foram de 16,8, 66,3, 67,1, 82,0 e 79,6%, respectivamente, na camada de 25-40 cm, em relação aos dados da camada 0-15 cm.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, José Ronaldo Coelho2000-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5858Pesquisa Agropecuaria Brasileira; v.35, n.5, maio 2000; 1055-1061Pesquisa Agropecuária Brasileira; v.35, n.5, maio 2000; 1055-10611678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5858/2962info:eu-repo/semantics/openAccess2010-07-29T18:30:00Zoai:ojs.seer.sct.embrapa.br:article/5858Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-29T18:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
