ENERGY DISPERSIVE X-RAY FLUORESCENCE APPLIED TO MAPPING OF TREE STEMS IN CAMPINAS, SAO PAULO
(Soc Brasileira QuimicaSao PauloBrasil, 2009)
Light absorption, light use efficiency and productivity of 16 contrasted genotypes of several Eucalyptus species along a 6-year rotation in Brazil
(2019-10-01)
Stemwood productivity in forest ecosystems depends on the amount of light absorbed by the trees (APAR) and on the Light Use Efficiency (LUE), i.e. the amount of stemwood produced per amount of absorbed light. In fertilized ...
Potassium fertilization increases water-use efficiency for stem biomass production without affecting intrinsic water-use efficiency in Eucalyptus grandis plantations
(Elsevier B.V., 2016-03-15)
Adaptive strategies to improve tree water-use efficiency (WUE) are required to meet the global demand for wood in a future drier climate. A large-scale throughfall exclusion experiment was set up in Brazil to study the ...
Biomass production and nutrient content in different Eucalyptus genotypes in Pampa Gaucho, Brazil
(Univ Federal Rural Pernambuco, 2019-01-01)
The objective of this study was to estimate the biomass, nutrient stocks, and simulate the export of nutrients, in different genotypes of Eucalyptus. The experiment was conducted in Sao Gabriel, RS, Brazil, in 43-month-old ...
Biomassa e estoque de nutrientes em diferentes materiais genéticos de Eucalyptus no sul do Brasil
(Universidade Federal de Santa MariaBrasilRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalCentro de Ciências Rurais, 2018-02-23)
The study of biomass production and nutrient accumulation in Eucalyptus stands as the basis for understanding nutrient dynamics in forest sites. The objective of this work was to estimate the biomass and nutrient stock of ...
The interactions of climate, spacing and genetics on clonal Eucalyptus plantations across Brazil and Uruguay
(Elsevier B.V., 2017-12-01)
Intensively managed plantations account for 1.5% of the world's forests, but they meet one-third of the demand for wood products. Eucalyptus plantations are among the most productive, with rates of growth depending heavily ...
Estimation of nutrient export in eucalypts genotypes under different harvest intensities in Southern BrazilEstimación de la exportación de nutrientes en genotipos de eucalipto bajo diferentes intensidades de cosecha en el sur de Brasil
(2020-03-01)
The study of the nutrients removed with forest harvesting is presented as an essential fator favoring the sustainable use of forest stands. The research was carried out in an experimental area in Horto Florestal Terra Dura ...
Quantificação da biomassa e nutrientes em uma floresta estacional decidual em Itaara-RS, Brasil
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2005-09-23)
This study was conducted in a farm belonging to Military Brigade in the Itaara county, RS. The main objective was to quantify the nutrient stocks in the soil and the above ground biomass. The second aim was to evaluate the ...
Can intensive management accelerate the restoration of Brazil`s Atlantic forests?
(ELSEVIER SCIENCE BV, 2010)
Only 7% of the once extensive forest along the eastern coast of Brazil remains, and much of that is degraded and threatened by agricultural expansion and urbanization. We wondered if methods similar to those developed to ...
