O levantamento de solos e um dos ramos da pedologia que trata da cartografia de solos. No presente estudo o objetivo foi realizar um mapeamento de solos na escala 1:25.000 na area da bacia do rio Natuba que esta localizada na Zona da Mata Centro de Pernambuco abrangendo uma area de aproximadamente 39 km². Inicialmente foi realizado um reconhecimento morfologico dos solos da area, em diferentes topossequencias, com exames de solos na proporcao de 3 a 4 por km². O mapeamento e a classificacao taxonomica dos solos foram realizados conforme normas, procedimentos, e criterios adotados pela Embrapa Solos. Com as informacoes morfologicas dos solos foi possivel delimitar as unidades de mapeamento da area e definir os locais para amostragens dos perfis solos. Em acordo com a escala de trabalho, foram descritos e coletados 15 perfis de solo e realizados 144 exames morfologicos de solos em toda area mapeada. Foram identificadas oito classes de solo, a nivel de subordem, e definidas dezenove unidades de mapeamento de solos. Ficou evidente o forte controle exercido pelo material de origem e pelo relevo na geografia e na fertilidade natural dos solos. As subordens de solos identificados foram Latossolos Amarelos, Argissolos Amarelos, Argissolos Vermelho-Amarelos, Argissolos Vermelhos, Argissolos Acinzentados, Neossolos Fuvicos, Neossolos Litolicos e Gleissolos Haplicos. 800x600 Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif";} A B S T R A C T The soil survey is a branch of pedology that deals with the mapping of soils. In this study the objective was to conduct a soil mapping at the scale 1:25,000 in the area of the river basin which is located in Natuba at Zona da Mata Center of Pernambuco covering an area of, approximately, 39 km². Initially we carried out recognition of morphology of the soil at region, at different toposequence, with tests of soil in a proportion of 3 to 4 km 2 . The mapping and taxonomic classification of soils were performed according to standards, procedures and criteria adopted by Embrapa Solos. With the morphological information of the soils was possibble to delimit the units of mapping the area and set the locations for sampling of soil profiles. In accordance with the scale of work, were described and collected 15 soil profiles and 144 morphological examinations soil, performed throughout the mapped area. Were identified eight classes of soil, at suborder level, and were defined nineteen units of soil mapping. It was evident the strong control exercised by the parent material and by topography, at the geography and at the natural soil fertility. The Suborders of soil were identified Oxisols Yellow, Yellow Ultisols, Red-Yellow Ultisols, Red Ultisols, Gray Ultisols, Fluvisols, Lithic Entisols and Gleysols Haplic. Keywords: pedology, cartography, physical properties and chemical of soil.
