Variability and spatial correlation of aggregates and organic carbon in Indian Dark Earth in Apuí region, AM.

Variabilidade e correlação espacial de agregados e carbono orgânico em Terra Preta de Índio na região do Apuí, AM. The study of variability associated to the soil attributes spatial correlation, as OC and its relations with other physical attributes in anthropogenic environments with a so-intimate character like the IDEs, is unprecedented in the Amazonian region. Based on we presented before, in this work we evaluated the variability and spatial correlation of organic carbon, bulk density, as well aggregates classes in area of Indian Dark Earth in Apuí, southern of Amazonas
