Resumo: | The objective of this work was to assess the spatial variability of the chemical attributes of two coffee areas, managed in conventional and organic crop systems, and to calculate the percent of variation between them. In each area, a 40-point-mesh was sampled at 0-0.10 m and 0.10-0.20 m layers, within the crown projection, for pH, SB, K, P, Ca and Mg analysis. The data were analyzed through descriptive statistics and geostatistics. From the soil chemical attributes map, the percent of variation between the systems’ chemical attributes was determined by GIS algebraic operations. The results show that the soil chemical attributes present a spatial dependence in both systems and layers. Analysis of the soil chemical attributes showed less spatial variability in the organic system, in relation to the conventional, indicating homogeneous zones for different fertilizer applications. The percent of variation of the chemical attributes in the conventional system, in relation to the organic, at 0-0.10 m and 0.10-0.20m layers are 54.80% and 35.61%, respectively. |

Em cada área foi construída uma malha com 40 pontos georreferenciados com amostragens do solo realizadas nas camadas de 0-0,10 m e 0,10-0,20 m, na projeção da copa do cafeeiro, para análises de pH, SB, K, P, Ca e Mg. Os dados foram analisados por estatística descritiva e geoestatística. A partir dos mapas dos atributos químicos do solo foi calculado o mapa do porcentual da diferença dos atributos químicos do manejo convencional em relação ao manejo orgânico, por meio de operações algébricas no sistema de informações geográficas. Os resultados indicam que todos os atributos químicos do solo apresentam dependência espacial nos dois manejos e nas duas camadas. Na análise dos atributos químicos do solo observa-se menor variabilidade espacial na área de manejo orgânico em relação ao manejo convencional, indicando zonas homogêneas para a aplicação de adubos de forma diferenciada. O porcentual das diferenças do manejo convencional em relação ao manejo orgânico dos atributos químicos na área, na camada de 0-0,10 m e 0,10-0,20 m é de 54,80% e 35,61%, respectivamente.Editora UFLA2011-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/350Coffee Science - ISSN 1984-3909; Vol. 5 No. 2 (2010); 173-182Coffee Science; Vol. 5 Núm. 2 (2010); 173-182Coffee Science; v. 5 n. 2 (2010); 173-1821984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/350/pdfCopyright (c) 2011 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessFagioli da Silva, AlessandraSoares de Souza Lima, JuliãoSoares de Souza, GustavoBatista de Oliveira, Rone2013-02-24T14:09:42Zoai:coffeescience.ufla.br:article/350Revistahttps://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:2024-05-21T19:53:38.644056Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
