Resumo: The objective of this work was to identify the spatial structure dependence of soil attributes and its interference on the production of epigeal biomass of Urochloa brizantha. A Typic Hapludox was sampled at geocoded grid points in order to determine soil physical and chemical properties and the epigeal biomass production of pasture during the summer and fall seasons of 2010/2011. Spatial dependence of variables was verified by geostatistical analysis using construction and adjustment of semivariograms, ordinary kriging interpolation, and spatial maps. Spatial dependence occurred for some physical and chemical soil properties (sand, density, penetration resistance, infiltration, pH, MO, P, K, Ca, Mg, H+Al, Al, CEC, and base saturation), and for pasture biomass measured in the summer and fall seasons. Spatial analysis of soil physical attributes allows identifying areas with the highest pasture degradation. Biomass pasture is more influenced by the soil physical attributes than by the chemical ones.

Amostras de Latossolo Vermelho‑Amarelo foram coletadas em rede de pontos georreferenciados, para a determinação de atributos físicos e químicos do solo e da produção de biomassa epígea da pastagem, no verão e outono de 2010/2011. Verificou-se dependência espacial das variáveis, por meio de análise geoestatística com construção e ajuste de semivariogramas, interpolação por krigagem ordinária e espacialização em mapas de isolinhas. A dependência espacial ocorreu para alguns atributos físicos e químicos do solo (areia, densidade, resistência à penetração, infiltração, pH, MO, P, K, Ca, Mg, H+Al, Al, CTC e V), e para a biomassa da pastagem medida nas estações verão e outono. A análise espacial de atributos físicos do solo permite identificar áreas degradadas da pastagem. A biomassa da pastagem é mais influenciada pelos atributos físicos do solo do que pelos químicos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmbrapa SEGGrego, Celia ReginaRodrigues, Cristina Aparecida GonçalvesNogueira, Sandra FurlanGimenes, Flávia Maria AndradeOliveira, Alex deAlmeida, Caio Gusmão Ferrer deFurtado, André Luiz dos SantosDemarchi, João José Assumpção de Abreu2012-11-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/11484Pesquisa Agropecuaria Brasileira; v.47, n.9, set. 2012: Número Temático Geotecnologias; 1404-1412Pesquisa Agropecuária Brasileira; v.47, n.9, set. 2012: Número Temático Geotecnologias; 1404-14121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/11484/8005https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11484/7021https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11484/7022info:eu-repo/semantics/openAccess2012-11-13T21:40:10Zoai:ojs.seer.sct.embrapa.br:article/11484Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-11-13T21:40:10Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
