Resumo: The chemical characteristics of soils in the Brazilian Cerrado are easily changed by human interventions. The aim of this study was to evaluate the spatial variability of chemical properties in Entisol Typic due to Cerrado cleaning substited by pasture in the region of Araguaina (TO), Brazil. Samples were taken in an irregular grid in an area of 13.11 ha, in the depth of 0 to 20 cm, to determine the levels of organic matter (OM), Al3+, P, K+, Ca2+, Mg2+ and pH values, sum of bases (SB), capacity cation exchange to pH 7.0 (CECpH 7), ability to effective cation exchange (CECe), base saturation (V%) and aluminum saturation (m%). The soil chemical properties were analyzed using descriptive statistics and had average compared by the Tukey test, at 5% probability, using geostatistics and interpolated by ordinary kriging. The ranges of spatial dependence of the chemical variables pH and Ca2+ in the soil were lower than the others (OM, Al3+, P, K+, Mg2+, SB, CTCpH7, , CECe and V%), indicating that they have a smaller continuity in the spatial distribution in Entisol Typic depending on the conversion of the Cerrado grasslands.

O objetivo desse estudo foi avaliar a variabilidade espacial das propriedades químicas em um Neossolo Quartzarênico Órtico típico, em função da substituição do Cerrado por Pastagem, na região de Araguaína (TO), Brasil. Foram feitas amostragens do solo em uma malha irregular em área de 13,11 ha, na profundidade de 0 a 20 cm, para determinação dos teores de matéria orgânica (MO), Al3+, P, K+, Ca2+, Mg2+ , valores de pH, soma de bases (SB), capacidade de troca de cátions em pH 7,0 (CTCpH 7), capacidade de troca de cátions efetiva (CTCe), saturação por bases - V% e saturação por alumínio - m%. As propriedades químicas do solo foram analisadas por estatística descritiva e tiveram suas médias comparadas pelo teste de Tukey, a 5% probabilidade, utilizando geoestatístico e interpolação por krigagem ordinária. Os alcances de dependência espacial dos atributos químicos pH e Ca2+ do solo foram menores que os demais (MO, Al3+, P, K+, Mg2+, SB, CTCpH 7, CTCe e V%), indicando que eles apresentam menor continuidade na distribuição espacial em Neossolo Quartzarênico Órtico típico, em função da conversão do Cerrado em Pastagem.Universidade Federal de Viçosa - UFV2011-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/16410.13083/reveng.v19i4.182Engineering in Agriculture; Vol. 19 No. 4 (2011); 334-347Revista Engenharia na Agricultura - REVENG; v. 19 n. 4 (2011); 334-3472175-68131414-398410.13083/reveng.v19i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/164/134da Silva Neto, Sabino Pereirados Santos, Antonio ClementinoSilva, José Expedito Cavalcante dainfo:eu-repo/semantics/openAccess2023-01-19T12:54:59Zoai:ojs.periodicos.ufv.br:article/164Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:54:59Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
