Use of airborne radar images and machine learning algorithms to map soil clay, silt, and sand contents in remote areas under the Amazon rainforest. Authorship: FERREIRA, A. C. de S.; CEDDIA, M. B.; COSTA, E. M.; PINHEIRO, E. F. M.; NASCIMENTO, M. M. do; VASQUES, G. M. Soil texture has a great influence on the physical-hydric and chemical behavior of soils. In the Amazon regions, due to the presence of dense forest cover and limited access to roads, carrying out sur... ... Repository: BDPA Publication year: 2022
Soil carbon stock and particle size fractions in the Central Amazon predicted from remotely sensed relief, multispectral and radar data. Authorship: CEDDIA, M. B.; GOMES, A. S.; VASQUES, G. M.; PINHEIRO, E. F. M. Soils from the remote areas of the Amazon Rainforest in Brazil are poorly mapped due to the presence of dense forest and lack of access routes. The use of covariates derived from multispectral and rad... ... Repository: BDPA Publication year: 2017
Prediction of soil physical and chemical properties by visible and near-infrared diffuse reflectance spectroscopy in the Central Amazon. Authorship: PINHEIRO, E. F. M.; CEDDIA, M. B.; CLINGENSMITH, C. M.; GRUNWALD, S.; VASQUES, G. de M. Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physic... ... Repository: BDPA Publication year: 2017
Biogas production from dairy cattle manure, under organic and conventional production systems. Authorship: MATOS, C. F.; PAES, J. L.; PINHEIRO, E. F. M.; CAMPOS, D. V. B. de The purpose of this study was to evaluate the production of biogas, as well as the biogas production potential resulting from the anaerobic biodigestion of dairy cattle manure under organic (CMOS) and... ...
