Resumo: | Soil is the natural resources the most exploited in the world, mainly due to the current need for food production. However, the use of agricultural practices mistakenly brings the degradation of their properties, especially in rugged areas. Thus the research aimed to evaluate the chemical, physical and mineralogical soil at different positions in the landscape, in soils under the use of Agriculture, Pasture and Forest-native, in Areia-PB, micro-region of Brejo Paraibano. Samples were collected in eighteen (18) points in the areas of agriculture and grazing, and six (6) points in kills native area in three relief positions (Top, middle and bottom) and at three depths (0 -10, 10-20 and 20-40 cm) between January and June 2014. The samples were subjected to soil texture analysis, physical and chemical attributes, and analysis of fluorescence X-ray and diffraction X-ray for the characterization of total oxides and mineralogy. The tests were performed at the Physics Laboratory of Department of Soil Soil and Rural Engineering - DSER / UFPB / Campus II, in the Laboratory of Analytical Chemistry of the National Institute for the Semi-Arid – INSA, in the New Materials Technology Laboratory (LTNM) of Development Institute of the State of Paraíba – UFPB and Rapid Solidification Laboratory of Technology Center of the Federal University of Paraíba (Campus I). In the mineralogical composition of the agricultural area of the samples was evidenced the predominance of primary minerals such as quartz, supporting the textural classification of the soil of the area. In the forest area, the mineralogical composition was homogeneous, with the predominance of quartz and kaolinite and goethite occur in all collected points, while the pasture area is composed mainly of quartz, kaolinite and feldspar. In the physical analysis were observed Sandy and clayey-sandy textures in the areas of use of Agriculture, Forest and Pasture, respectively. According to the results of chemical properties, the area of Agriculture presented a greater supply of nutrients, especially the P content in the soil in the Top Third position (101.50 mg dm-3), showing the effect of transport material on the side and not as differing depths (91,53a, 87,38a and 76,23a mg dm-3, respectively). The forest area showed most of the nutrients concentrated in the depth of 0-10 cm and higher acidity among the evaluated areas, but almost no effect on the positions on the slope. The grassland area had higher Ca2+ levels (1,03a cmolc dm-3) and K + (0,23a cmolc dm-3) in the Bottom third position and a greater concentration of P in the Top Third position (43,10a mg dm-3). In the analysis of total oxide content it was observed that P2O5 content of the agricultural area was higher at shallow depths, as well as in the bottom third position (0.45, 0.42 and 0.36%, in their depths). In the forest area there was higher Al2O3 contents when compared with other areas, while the pasture area presented oxide contents near the Agricultural Area results. |

Entretanto, o uso de práticas agrícolas de maneira equivocada acarreta na degradação de suas propriedades, principalmente em áreas de relevo acidentado. Desse modo a pesquisa teve como objetivo principal avaliar as propriedades químicas, físicas e mineralógicas do solo em diferentes posições na encosta, em solos sob o uso de Agricultura, Pastagem e Mata-nativa, no município de Areia-PB, na Microrregião do Brejo Paraibano. Foram coletadas amostras em 18 (dezoito) pontos nas áreas de agricultura e pastagem, e 6 (seis) pontos na área de mata-nativa, em três posições do relevo (Terço Superior, Terço Médio e Terço Inferior) e em três profundidades (0-10, 10-20 e 20-40 cm), entre Janeiro e Junho de 2014. As amostras foram submetidas a análises de textura do solo, atributos físicos e químicos, e análises de Fluorescência e Difração de Raios-X para as caracterizações de óxidos totais e mineralogia. Os ensaios foram realizados no Laboratório de Física do Solo do Departamento de Solos e Engenharia Rural – DSER/UFPB/Campus II, no Laboratório Lab-Sede de Química Analítica do Instituto Nacional do Semi-Árido – INSA e nos Laboratórios de Tecnologia de Novos Materiais (LTNM) do Instituto UFPB de Desenvolvimento do Estado da Paraíba e de Solidificação Rápida do Centro de Tecnologia da Universidade Federal da Paraíba (Campus I). Na composição mineralógica das amostras da área de agricultura foi evidenciada a predominância de minerais primários como o Quartzo, corroborando com a classificação textural do solo da área. Na área de Mata, a composição mineralógica mostrou-se homogênea, com o predomínio de Quartzo e ocorrência de Caulinita e Goetita em todos os pontos coletados, enquanto a área de pastagem é composta basicamente por quartzo, caulinita e feldspato. Nas análises físicas foram observadas texturas arenosa, argilosa e arenosa, nas áreas do uso de Agricultura, Mata e Pastagem, respectivamente. De acordo com os resultados dos atributos químicos, a área de Agricultura apresentou os um aporte maior de nutrientes, com destaque para os teores de P no solo na posição de Terço Inferior (101,50 mg dm-3), evidenciando o efeito do transporte de material na encosta e não diferindo quanto as profundidades (91,53a, 87,38a e 76,23a mg dm-3, respectivamente). A área de Mata apresentou maior parte dos nutrientes concentrados na profundidade de 0-10 cm e maior acidez dentre as áreas avaliadas, porém quase nenhum efeito relativo às posições na encosta. A área de Pastagem teve maiores teores de Ca2+ (1,03a cmolcdm-3) e K+ (0,23a cmolcdm-3) na posição do terço inferior e maior concentração de P na posição de Terço Superior (43,10a mg dm-3). Na analise de teores de óxidos totais observou-se que os teores de P2O5 da área de Agricultura foram maiores nas profundidades mais superficiais, bem como na posição de Terço Inferior (0,45; 0,42 e 0,36%, nas respectivas profundidades). Na área de Mata observou-se maiores teores de Al2O3 quando comparados com as demais áreas, enquanto a área de pastagem apresentou teores de óxidos próximos aos resultados da área de Agricultura.Universidade Federal da ParaíbaBrasilSolos e Engenharia RuralPrograma de Pós-Graduação em Ciência do SoloUFPBSilva, Kelly Cristiane Gomes dahttp://lattes.cnpq.br/0678485152961068Sousa, Cristiano dos Santos2019-09-03T18:05:06Z2015-06-162019-09-03T18:05:06Z2015-03-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttps://repositorio.ufpb.br/jspui/handle/123456789/15518porAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações da UFPBinstname:Universidade Federal da Paraíba (UFPB)instacron:UFPB2019-09-04T06:09:01Zoai:repositorio.ufpb.br:123456789/15518Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufpb.br/PUBhttp://tede.biblioteca.ufpb.br:8080/oai/requestdiretoria@ufpb.br|| diretoria@ufpb.bropendoar:2019-09-04T06:09:01Biblioteca Digital de Teses e Dissertações da UFPB - Universidade Federal da Paraíba (UFPB)false |
