Resumo: Landscapes formed on Barreiras Formation sediments occupy signifi cant area on Brazilian territory. Many of these landscapes have highly intensive agricultural use, dueto favorable climate and topography. The objective of this study was to characterize and to compare soil profi les situated on non-dissected coastal plains from southern Bahia to Alagoas, occurring under natural vegetation (forest) and agricultural use. Seven soil profi leswere analyzed and data from six soil profi les obtained in other works were incorporated. Particle size distribution, organic C (OC), Al, Ca, Mg, Al+H, K, Na, P, Fe, Ti and Si were determined. Clay mineralogy was analyzed by X-ray diffraction. Soil profi les occur on fl at relief, have yellow color, weak small to medium subangular blocky structure on B horizon and sub-superfi cial cohesive character. Texture was the most signifi cant attribute thatdifferentiated soil profi les from each other. All soils have low Fe content. X-ray diffraction results showed kaolinite dominance in the clay fraction. The soil OC was the only attribute tested that signifi cantly varied between the surface materials of forest soils and the cultivatedsystems (sugarcane, orange, coconut and eucalyptus).

Muitas dessas paisagens apresentam elevada intensidadede uso agrícola, por uma combinação de clima e ocorrência de relevo plano a quase plano. O presente trabalho teve como objetivo caracterizar e comparar perfis de solo de superfícies pouco a medianamente entalhadas dos tabuleiros costeiros entre o sul da Bahia e Alagoas, descritos sob coberturas vegetais naturais (florestas) e cultivadas. Foram analisados sete perfisde solo e utilizados mais seis perfi s, de outros trabalhos. Nas amostras, foi determinado: granulometria, C orgânico, Al, Ca, Mg, Al+H, K, Na, P ,Fe, Ti e Si. Foi também analisada a difração de raios-X na fração argila. Os perfis de solo apresentam relevo plano, cores amarelas, estrutura do horizonte B fraca pequena a média em blocos subangulares e caráter coeso em subsuperfície. A textura é o atributo que mais diferencia os solos estudados entre si. Todos os solos são hipoférricose as difrações de raios-X mostram a predominância de caulinita na fração argila dos solos estudados. O CO foi o único atributo de solo testado que variou significativamente entre os materiais superficiais dos solos de floresta, comparativamente aos dos sistemas cultivados (cana, laranja, coco e eucalipto).Embrapa Florestas2012-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/32410.4336/2012.pfb.32.71.233Pesquisa Florestal Brasileira; v. 32 n. 71 (2012): jul./set.; 233Pesquisa Florestal Brasileira; Vol. 32 No. 71 (2012): jul./set.; 2331983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/324/pdfCopyright (c) 2012 Joao Bosco Vasconcellos Gomes, José Coelho de Araújo Filho, Nilton Curihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessGomes, Joao Bosco VasconcellosAraújo Filho, José Coelho deCuri, Nilton2017-04-28T12:56:05Zoai:pfb.cnpf.embrapa.br/pfb:article/324Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:56:05Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
