Resumo: | The soil is one of the natural resources more intensely used for food production, being subject to have its productive capacity reduced by the erosion, as a result of its inadequate use and management. The erosion not only carries particles from the soil, but also carries organic matter, important factor to nutrients availability to the plants. Hence this work aimed to evaluate the influence of conservation practices for the soil and water losses by the hydric erosion, in a Fluvic Neossol in the semiarid zone of Pernambuco State, with the purpose of producing simple and low cost recommendations, for the local farmers, appropriate and efficient in reducing the hydric erosion. Simulated rain with intensities between 54 and 60 mm/h have been applied on the following treatments: bean cultivated in level (N1) with rock barriers between each row of plantation, in the spacing of 0.5 m; bean cultivated in level (N2) with rock barriers in the spacing of 1.0 m; bean planted downslope (DS); bean planted in level with mulching cover (MC), using bean straws; cleared bare soil (CB) and natural covering (CN). The erosive values had been calculated from the collections of the runoff material. Amongst the evaluated treatments, the mulched cover, on average, exhibit reduction of 86,91% in the soil losses, with values close to the one to the ideal condition of covering, which is the natural condition. The results of the total organiccarbon lost in the sediments of the treatment without conservation practice had prresented significant amounts of carbon being carried out to the lower parts of the plot. Conditions MC and CN had presented reduction of 94.73 and 98.70% in relation to the cleared bare soil plot. Amongst the conservation practice studied, the mulching cover presented the highest reduction in the soil erosion. |

Dissertação (Programa de Pós-Graduação em Engenharia Agrícola) - Universidade Federal Rural de Pernambuco, Recife.http://www.tede2.ufrpe.br:8080/tede2/handle/tede2/5705The soil is one of the natural resources more intensely used for food production, being subject to have its productive capacity reduced by the erosion, as a result of its inadequate use and management.

A erosão além de transportar partículas do solo, também transporta matéria orgânica, importante fator para disponibilidade de nutrientes às plantas. Neste sentido este trabalho teve como objetivo avaliar a influência de práticas conservacionistas nas perdas de solo e água por erosão hídrica, num Neossolo Flúvico do Semiárido Pernambucano, com a finalidade de se obter uma recomendação de manejo simples e de baixo custo, para os agricultores, que seja eficaz na redução da erosão hídrica do solo. Para isto foram aplicadas chuvas simuladas com intensidades entre 54 e 60 mm/h sobre os seguintes tratamentos: feijoeiro em nível (N1) com barramentos de pedra entre cada fileira de plantio do feijoeiro, no espaçamento de 0,5 m; feijoeiro cultivado em nível (N2) com barramentos de pedra no espaçamento 1,0 m; feijoeiro cultivado morro abaixo (MA); feijoeiro em nível com cobertura morta (CM), onde a cobertura utilizada foi palha de feijão; desmatada (D) e cobertura natural (N). As taxas erosivas foram calculadas a partir das coletas do material da enxurrada. Dentre os tratamentos avaliados, a coberturamorta permitiu, em média, redução de 86,91% nas perdas de solo, com valores próximos ao da condição ideal de cobertura, que é a condição natural. Os resultados do total de carbono orgânico perdido nos sedimentos das condições sem prática conservacionista revelaram quantidades significativas de carbono sendo transportadas para as partes mais baixas do terreno. As condições CM e CN apresentaram redução de 94,73 e de 98,70% em relação à parcela desmatada. Dentre as práticas conservacionistas estudadas, a cobertura morta apresentou maior redução da erosão do solo.Submitted by (lucia.rodrigues@ufrpe.br) on 2016-10-14T12:14:42Z No. of bitstreams: 1 Thais Emanuelle Santos.pdf: 1022250 bytes, checksum: 063e006c3bb3362ee6f61cb2d0973c61 (MD5)Made available in DSpace on 2016-10-14T12:14:42Z (GMT).
