Assessing the capability of MODIS to monitor mixed pastures with high-intensity...
Silva, Yane de Freitas da, 1990-; Reis, Aliny Aparecida dos; Werner, João Paulo Sampaio, 1993-; Valadares, Rafael VasconcelosAbstract: MODIS time series carries valuable long-term data essential to support several studies such as biogeochemical modelling. However, there is a lack of validation studies applying MODIS data at a fine-scale to monitor pasture management practices. In this study, we assessed the potential of MODIS sensor in monitoring at a fine-scale four intensively managed mixed-pastures fields located in São Paulo Stat...
Monitoring pasture aboveground biomass and canopy height in an integrated crop–...
Reis, Aliny Aparecida dos; Werner, João Paulo Sampaio, 1993-; Silva, Bruna Caroline da, 1990-; Figueiredo, Gleyce Kelly Dantas Araújo, 1984-Abstract: Fast and accurate quantification of the available pasture biomass is essential to support grazing management decisions in intensively managed fields. The increasing temporal and spatial resolutions offered by the new generation of orbital platforms, such as Planet CubeSat satellites, have improved the capability of monitoring pasture biomass using remotely sensed data. Here, we assessed the feasibilit...
Efeito de local e espaçamento na qualidade do carvão vegetal de um clone de Euc...
Reis, Aliny Aparecida dos; Melo, Isabel Cristina Nogueira Alves de; Protásio, Thiago de Paula; Trugilho, Paulo FernandoO objetivo desse trabalho foi avaliar o efeito do local e do espaçamento de plantio na produção e na qualidade do carvão vegetal de um clone de Eucalyptus urophylla. Amostraram-se cinco discos ao longo do fuste das árvores do clone 3336. As carbonizações foram realizadas em uma mufla com temperatura final de 450 ºC. Foram avaliados os rendimentos da carbonização, a análise química imediata, a densidade básica d...
Using remote sensing images for stratification of the cerrado in forest invento...
Silva, Sérgio Teixeira da; Mello, José Marcio de; Acerbi Junior, Fausto Weimar; Reis, Aliny Aparecida dos; Raimundo, Marcel RegisRemote sensing imagery can be a very useful auxiliary tool for native forests inventory. Thus, the objective of this study was to evaluate the stratification of a cerrado (Brazilian savanna) patch based on visual image interpretation techniques as well as to compare the errors from two sampling designs, the Stratified Random Sampling (SRS) and the Systematic Sampling (SS).The study area corresponds to a cerrado...
Steel and energetic potential of charcoal of Eucalyptus spp. clones at 42 month...
Protásio, Thiago de Paula; Couto, Allan Motta; Reis, Aliny Aparecida dos; Trugilho, Paulo Fernando; Godinho, Tayana PedrozoThe aim of this study was to evaluate the steel and energetic potential of charcoal of clones of Eucalyptus grandis and Eucalyptus urophylla at 42 months of age. Wood from seven clones were used. The carbonizations were performed in an electric furnace (muffle) with final temperature of 450 °C. The carbonization yields, immediate and elemental chemical composition, higher and low heating value, apparent relativ...
Wood composition and charcoal of Eucalyptus urophylla in different planting loc...
Reis, Aliny Aparecida dos; Protásio, Thiago de Paula; Melo, Isabel Cristina Nogueira Alves de; Trugilho, Paulo FernandoThis work aimed to evaluate the effect of planting sites on the elemental chemical composition of Eucalyptus urophylla wood and the quality of its charcoal and to verify the statistical relations among the properties measured in wood and charcoal. It was used twelve 7-years old trees from E. urophylla clone from Curvelo, Itacambira and Turmalina counties located in Minas Gerais State, Brazil. The elemental chem...
