Resumo: | In regions of ecotone soil chemical properties show a wide variation, resulting from the interplay between the factors of formation, vegetation cover and use. The aim of this study was to evaluate the spatial variability of chemical attributes of a Entisol transition zone between the Savannah and Amazonian biome in different forms of land use and management (forest, scrub, bare soil, crop, pasture and savanna) in the region of Araguaína city (TO). Samples were ground in an irregular mesh in an area of 26.08 ha, the depth of 0 to 20 cm to determine the levels of organic matter, P, K+, Ca2+, Mg2+ and pH, sum of bases, CECpH 7, CECe, V%, m%. The soil chemical properties were analyzed using descriptive statistics, comparison of average by Tukey test at 5% significance to the study and geostatistical kriging. The ranges of spatial dependence of the chemical organic matter, Al3+, K+, Mg+, and SB CECe soil were higher than the others (pH, P, Ca2+, CECpH 7, V%, m%), indicating that these are more discontinuity in the spatial distribution in Entisol three forms of agricultural use and vegetation cover three of the transition Savannah-Amazon. Thus, management strategies of correction and mineral fertilizers in an ecotone can be fitted according to the representations of studies and geostatistical kriging interpolation in homogeneous areas. |

O objetivo do presente estudo foi avaliar a variabilidade espacial de atributos químicos de Neossolo Quartzarênico Órtico típico na zona de transição entre o Bioma Cerrado e o Amazônico sob diferentes formas de uso e manejo (floresta, capoeira, solo desnudo, cultura agrícola, pastagem e cerradão) na região de Araguaína (TO). Previamente a implantação do experimento foram realizadas amostragens de solo em uma malha irregular com área de 26,08 ha, na profundidade de 0 a 20 cm para determinação dos teores de matéria orgânica (M.O.), P, K+, Ca2+, Mg2+ e os valores de pH, Soma de bases (SB), capacidade de troca de cátions (CTCpH 7,0), capacidade de troca de cátions efetiva (CTCe), saturação por base (V%) e saturação por alumínio (m%). Os dados obtidos de cada um dos atributos químicos do solo foram submetidos à analises de estatística descritiva, à comparação de média pelo teste de Tukey ao nível de 5% de significância, ao estudo geoestatístico e interpolação por krigagem. Os alcances de dependência espacial dos atributos químicos M.O. Al3+, K+, Mg+, SB e CTCe do solo foram maiores que os demais (pH, P, Ca2+, CTCpH 7, V% e m%), indicando que esses apresentam maior descontinuidade na distribuição espacial em Neossolo Quartzarênico Órtico típico sob três formas de uso agrícola e de três coberturas vegetais de zona de transição Cerrado-Amazônia. As estratégias de manejo de correção e fertilização mineral em região de ecótono podem ser montadas em função das representações dos estudos geoestatísticos e de interpolações por krigagem nas zonas mais homogêneas.UEL2011-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/392510.5433/1679-0359.2011v32n2p541Semina: Ciências Agrárias; Vol. 32 No. 2 (2011); 541-552Semina: Ciências Agrárias; v. 32 n. 2 (2011); 541-5521679-03591676-546Xreponame:Semina.
