The perfect spatial intervention to manage the cultivation of the land, deriving from specific regions of the soil mapping, increases the agricultural productivity, as well as its clear gain. The relationships, spatial and Pearson, between eucalyptus data plant with some physical and chemical attributes of soil, in the growing season of 2011, in Selviria County, Mato Grosso do Sul State, Brazil (20° 20' S lat.; 51° 24' W long.), were studied in order to obtain the one that could have the best relationship in order to improve the wood productivity. Thus, a geostatistical grid was installed for the soil and plant data collection, it contained 120 sample points, in plantation of Eucalyptus camaldulensis of 2 years old. The soil was a Dystrophic Red Latosol (Haplic Acrustox) whit slope of 0.025m [m.sup.-1]. Due to their excellent relationship with wood productivity, the basis diameter of the crown and the bulk density showed management specific regions of soil whit high relation to eucalyptus wood productivity. Key words: soil management, precision agriculture, Eucalyptus camaldulensis. A correta intervencao espacial na administracao da lavoura, decorrente das zonas especificas de manejo do solo, aumenta a produtividade e a lucratividade agricola. No ano de 2010, em Selviria, Mato Grosso do Sul, Brasil (20° 20' S lat.; 51° 24' W long.) foram empregadas correlacoes, espaciais e de Pearson, entre dados da planta de eucalipto e alguns atributos fisico-quimicos do solo, visando encontrar aquele que se correlacionasse bem com a produtividade de madeira. Para tanto, instalou-se uma rede geoestatistica para a coleta de dados de solo e planta, com 120 pontos amostrais, num talhao de Eucalyptus camaldulensis de 2 anos. O solo foi um Latossolo Vermelho distrofico (Haplic Acrustox) com declive de 0,025m [m.sup.-1]. O diametro basal da copa e a densidade do solo, por resultarem estreitas correlacoes com o volume de madeira, evidenciaram zonas especificas de manejo do solo intimamente associadas a producao de madeira do eucalipto.
