Resumo: The soils of Espírito Santo State are low natural fertility level, which frequently limit crop yields due to deficiencies of some soil elements, however, it presents high production potential. The purpose of this work was to describe the spatial variability of attributes related to soil acidity (pH, potential acidity, aluminum, calcium, magnesium), organic matter and liming requirement in a conilon coffee plantation (Coffea canephora Pierre) in a typical dystrophic Yellow Latosol (LAd). The study was carried out in a farm area, in the Northern part of the state of Espírito Santo, Brazil. The experimental area was 20 x 61.6 m (1.232 m2) in a regular grid where 60 samples were equally spaced in grids of 5.6 x 5 m, at a soil depth of 0-20 cm. All property semivariograms disclosure were satisfactorily described by spherical model with a moderate and strong spatial structure with ranges of spatial structure varying from 8.0 m to 33.58 m.

Objetivou-se, no presente trabalho, descrever a variabilidade espacial dos atributos relacionado à acidez do solo (pH em água, acidez potencial, alumínio, cálcio e magnésio), matéria orgânica do solo e necessidade de calagem em uma lavoura de café conilon (Coffea conephora Pierre), localizada no Norte do estado do Espírito Santo. O experimento foi conduzido em uma lavoura de café conilon, plantada no espaçamento 1,8 x 1,0 m (5.555 plantas ha-1), em um Latossolo Amarelo distrófico típico (LAd). As análises de solo foram realizadas no Laboratório Agronômico de Análise de Solo, Folha e Água no Centro Universitário do Norte do Espírito Santo da Universidade Federal do Espírito Santo. O presente estudo foi instalado em uma malha retangular de 20 x 61,6 m (1.232 m2). Em cada ponto amostral foram coletadas amostras de solo, na profundidade de 0,0 – 0,2 m, totalizando 60 pontos amostrais, distanciados de 5,6 m entre linhas e 5,0 m na linha de plantio, as fileiras da lavoura estão dispostas no sentido Norte-Sul.2014-05-142017-08-01T20:08:22Z2017-08-01T20:08:22Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttp://www.coffeescience.ufla.br/index.php/Coffeescience/article/view/635http://repositorio.ufla.br/jspui/handle/1/13813Coffee Science; v. 9, n. 2 (2014); 275-283Coffee Science; v. 9, n. 2 (2014); 275-283Coffee Science; v. 9, n. 2 (2014); 275-2831984-39091809-6875reponame:Repositório Institucional da UFLAinstname:Universidade Federal de Lavras (UFLA)instacron:UFLAenghttp://www.coffeescience.ufla.br/index.php/Coffeescience/article/view/635/pdf_94http://www.coffeescience.ufla.br/index.php/Coffeescience/article/downloadSuppFile/635/487http://www.coffeescience.ufla.br/index.php/Coffeescience/article/downloadSuppFile/635/488http://www.coffeescience.ufla.br/index.php/Coffeescience/article/downloadSuppFile/635/489Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/openAccessSantos, Eduardo Oliveira de JesusGontijo, IvoneySilva, Marcelo Barreto daSantos, Eduardo Oliveira de JesusGontijo, IvoneySilva, Marcelo Barreto da2021-03-16T17:17:17Zoai:localhost:1/13813Repositório InstitucionalPUBhttp://repositorio.ufla.br/oai/requestnivaldo@ufla.br || repositorio.biblioteca@ufla.bropendoar:2021-03-16T17:17:17Repositório Institucional da UFLA - Universidade Federal de Lavras (UFLA)false
