Resumo: | Soil attributes may be influenced by the relief generating homogeneous productivity zones. From this hypothesis, we identified soil attribute groups, its spatial variability and relationship with productivity and relief by Factor Analysis (FA) and geostatistics methods. The study was conducted in a Oxisol cultivated with Conilon coffee in the State of Espírito Santo. The AF group in Factor 1 (F1) attributes related to soil aggregation was not associated with relief and productivity. Its spatial variability is influenced by management as showed by the lower spatial continuity and dependence in 0 – 0.10 m depth and by pure nugget effect in 0.10 – 0.20 m depth. From the factor 2 (F2), obtained in two depths, can be grouped soil attributes related to water retention, mainly the clay, microporosity and moisture which together increase at a higher altitude and lower slope where occur higher productivity areas. The spatial variability of F2 indicates greater continuity and spatial dependence, suggesting influence of relief in the spatial variation structure. |

Partindo-se dessa hipótese, foram identificados grupos de atributos do solo, sua variabilidade espacial, assim como sua relação com a produtividade e relevo, utilizando conjuntamente a Análise de Fatores (AF) e a geoestatistica. O estudo foi realizado em um Latossolo Vermelho-Amarelo cultivado com café Conilon no Estado do Espírito Santo. A AF permitiu agrupar no fator 1 (F1) atributos relacionados a agregação do solo que não apresentou relação com relevo e produtividade. Sua variabilidade espacial foi influenciada pelo manejo como demonstrado pela menor continuidade e dependência espacial na profundidade de 0 - 0,10 m e pelo efeito pepita puro na profundidade de 0,10 – 0,20 m. A partir do fator 2 (F2), obtidos das duas profundidades, consegue-se agrupar atributos do solo relacionados à retenção de água, destacando-se os teores de argila, a microporosidade e a umidade que aumentam conjuntamente em maior altitude e menor declive onde ocorrem zonas de maior produtividade. A maior continuidade e dependência espacial do F2 sugerem a influência do relevo na sua estrutura espacial.Editora UFLA2017-03-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1115Coffee Science - ISSN 1984-3909; Vol. 11 No. 4 (2016); 455 - 466Coffee Science; Vol. 11 Núm. 4 (2016); 455 - 466Coffee Science; v. 11 n. 4 (2016); 455 - 4661984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1115/pdf_1115https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1115/1618Copyright (c) 2017 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessBurak, Diego LangSantos, Danilo AndradePassos, Renato Ribeiro2017-03-23T14:17:28Zoai:coffeescience.ufla.br:article/1115Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:57.561064Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
