Soils characterization and classification in clean field, dirty field and fores...
Franciscon, Uilson; Costa Campos, Milton César; Campos Mantovanelli, Bruno; Coutrim dos Santos, Luís Antonio; Cunha, José Maurício da; Chechi, LeonardoThe soil and vegetation characteristics of the southern Amazonas region include highly weathered soils, high aluminum content and some hydromorphic conditions, its vegetation is composed from grasslands to small isolated trees and forest galleries along the rivers streams. In this way, this work aims to characterize and classify the soil in areas of clean field, dirty field, and forest in Humaitá region AM. Soi...
Spatial variability of aggregates and organic carbon under three different uses...
Gomes, Romário Pimenta; Campos, Milton César Costa; Soares, Marcelo Dayron Rodrigues; Silva, Douglas Marcelo Pinheiro; Cunha, José MaurícioIndian Black Earths (IBEs) are distributed throughout the Amazon. They are characterized by their high chemical fertility and agricultural potential. IBEs have high organic carbon, favouring the improvement of soil structure. This work aimed to evaluate the aggregates and organic carbon (OC) spatial variability in different IBEs in southern Amazonas. We evaluated the organic carbon spatial variability, mean wei...
Spatial variability of physical attributes of the soil in amazonian black soil ...
Cardoso Mota Júnior, Pedro; Costa Campos, Milton Cesar; Campos Mantovanelli, Bruno; Franciscon, Uilson; da Cunha, José MauricioThe conversion of natural ecosystems into agricultural systems causes significant changes in soil properties associated with the growing deforestation in the Amazon region influencing the destabilization of the ecosystem. Thus, it is aimed with this study was to evaluate the spatial variability of physical attributes of the soil in black Indian land area (ICC) under Conilon coffee cultivation. It was marked a s...
Chemical soil attributes evaluated by multivariate techniques and geostatistics...
Aquino, Renato Eleoterio de; Campos, Milton Cesar Costa; Soares, Marcelo Dayron Rodrigues; Oliveira, Ivanildo Amorim; Franciscon, UilsonStudies on the spatial behavior of soil attributes in the Amazon region are still very incipient. In this sense, the objective of this work was to evaluate the chemical attributes through multivariate techniques and geoestatistics in the area with agroforestry and sugarcane in Humaitá, AM, Brazil. The study was carried out in a farm in Humaitá city, Amazonas State. The studied area was divided into 70.00 m x 70...
Variabilidade espacial dos atributos físicos do solo em área de Terra Preta Arq...
SOARES, MARCELO DAYRON RODRIGUES; CAMPOS, MILTON CESAR COSTA; Souza, Zigomar Menezes; Brito, Wildson Benedito Mendes; Franciscon, UilsonNa Região Amazônica, as áreas com Terras Pretas Arqueológicas (TPAs) são cada vez mais fragmentadas devido ao desmatamento e ao uso agropecuário, o que provoca modificações principalmente nos atributos físicos do solo. O objetivo foi verificar a variabilidade espacial dos atributos físicos do solo em área de terra preta arqueológica sob pastagem na região de Manicoré, AM. Foi estabelecida uma malha amostral co...
Avaliação dos atributos do solo sob diferentes usos na região de Humaitá, Amazonas
CAMPOS, MILTON CESAR COSTA; MANTOVANELLI, BRUNO CAMPOS; SILVA, DIOGO ANDRE PINHEIRO; SANTOS, LUIS ANTONIO COUTRIN; GOMES, ROMARIO PIMENTAA implantação de atividades florestais, agrícolas e pecuária vem modificando a cobertura vegetal original de grande parte do território brasileiro. Ecossistemas naturais, como o cerrado e a floresta amazônica, vêm perdendo suas características originais e cedendo lugar para essas atividades. O objetivo foi avaliar os atributos do solo sob diferentes usos na fazenda Santa Rita, em Humaitá, Amazonas no período de...
