Biomass production and nutrient content in different Eucalyptus genotypes in Pa...
Santos, Kristiana Fiorentin dos; Ludvichak, Aline Aparecida; Queiroz, Tulio Baroso [UNESP]; Schumacher, Mauro Valdir; Araujo, Elias Frank deMade available in DSpace on 2020-12-10T17:03:14Z (GMT). No. of bitstreams: 0 Previous issue date: 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 stands. The selected trees were fractionated into leaves, branches, stembark and ...

Santos, Kristiana Fiorentin Dos; Ludvichak, Aline Aparecida; Queiroz, Túlio Baroso [UNESP]; Schumacher, Mauro Valdir; de Araújo, Elias FrankMade available in DSpace on 2020-12-12T01:33:37Z (GMT). No. of bitstreams: 0 Previous issue date: 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 in the municipality of Eldorado do Sul, RS, Brazil, where six Eucalyptus clones w...
Tree growth and nutrient dynamics in pine plantations in southern Brazil
Barros Filho, Nairam Felix de; Schumacher, Mauro Valdir; Neves, Júlio César Lima; Barros, Nairam Felix de; Valadares, Samuel VasconcelosFor the development of nutrient budget models to recommend lime and fertilizers for agricultural and forestry crops, curves of plant growth and nutrient accumulation are required. Information about how nutrients are partitioned between the different plant organs is also necessary, but still scarce for pine in Brazil. This study evaluated the growth, biomass partitioning, and nutrient dynamics in pine forests in...
Biomass and nutrients in Eucalyptus urograndis stands in southeastern Mountain ...
Viera, Márcio; Bonacina, Darlan Michel; Schumacher, Mauro Valdir; Calil, Francine Neves; Caldeira, Marcos Vinícius Winckler; Watzlawick, Luciano FarinhaThis study had as objective to quantify biomass and nutrients, in an 18 months Eucalyptus urograndis stand in southeastern mountain range, Piratini-RS. Twenty-four (24) plots (15.0 m x 22.5 m) were allocated; after that, one tree (with diameter at breast height) was felled in each plot. The tree was fractionated in the following fractions of above ground biomass: wood, bark, branches and leaves. Total biomass w...
Comparison among three different methods of vegetable tissue analysis.
Vaccaro, Sandro; Brun, Eleandro José; Schumacher, Mauro Valdir; König, Flávia Gizele; Kleinpaul, Isabel Sandra; Ceconi, Denise EsterThe objective of the present work was to compare three different methods of chemical analysis of vegetable tissue: the method of nitro-percloric digestion, Tedesco et al. and Adler & Wilcox. As material was analyzed 03 samples of the fraction leaves of the litter collected in each one of the two Seasonal Deciduous Forest fragments, collected in August of 1990 in the forest of the “Hill of the Elephant” (San...
Influence of different phosphorus doses on growth of Peltophoru dubium (Sprenge...
Schumacher, Mauro Valdir; Ceconi, Denise Ester; Santana, Cedinara ArrudaThis experiment was conducted with the objective to study the effects of different phosphorus doses in the growth of Canafístula seedlings (Peltophorum dubium). As substratum was used yellow-reddish argisoil, collected on the superficial layer (0-20 cm), which was discloded, homogenized, draught in the air, passed in a sieve of 2 mm and after a analyzed chemically. As complementary fertilization were added 10 m...
Hypsometrical Relation for Acacia mearnsii with Different Ages
Caldeira, Marcos Vinicius Winckler; Schumacher, Mauro Valdir; Scheeren, Luciano Weber; Barichello, Leonir Rodrigues; Watzlawick, Luciano FarinhaThis work had as objective to select mathematical models to predict the height of trees in function of DBH and age, in black wattle stands, Acacia mearnsii De Wild., in Southeastern region of the State of Rio Grande do Sul, Brazil. For the adjustment of the height data 19 mathematical equations were tested, being used arithmetic and logarithmic linear equations and one no-linear equation (Chapman-Richards). The...
Nutrients Concentration and Retranslocation in the Leaves and Branches of Acaci...
Caldeira, Marcos Vinicius Winckler; Schumacher, Mauro Valdir; Rodrigues, Loiva MariaThe senescence and fall of the leaves and branches are mechanisms where thetrees can recycle the nutrients by biochemical cycling and by biogeochemical cycling. The objective of this paper was to evaluate the nutrients retranslocation in the non-deciduous leaves and branches and also in the deciduous leaves and branches. The leaves and branches for analysis were collected in the subplots of Acacia mearnsii stan...
