Performance of Eucalyptus species to be used in forest-livestock integration sy...
Ribaski, JorgeThe objective of this study was to evaluate the performance of Eucalyptus grandis, E. dunnii, E. benthamii, E. badjensis and E. urograndis hybrid, in relation to survival and forest productivity in an experimental area located in Alegrete county, Rio Grande do Sul State, Brazil. The forest-livestock integration systems were composed of triple lines of trees, planted in 3 m x 2 m spacing, apart 30 m of each line...

Soil fertility and pasture productivity in a Grevillea robusta silvopastoral sy...
Radomski, Maria Izabel; Ribaski, JorgeThe “silver oak” is an Australian native tree species that was introduced in Brazil to shade agricultural species and forages (agrosilvopastoral systems).The aim of this work was to evaluate the silver oak effects on the soil fertility and the Brachiaria brizantha productivity in a silvopastoral system located at Arenito Caiuá geology, Tapejara, Paraná State, Brazil. Seven equidistant places were selected betwe...
Silvopastoral Systems as a Support for Rural Development in the Southwest Regio...
Ribaski, Sônia Aparecida Guetten; Hoeflich, Vitor Afonso; Ribaski, JorgeAn economic viability analysis was performed for different eucalypt wood production systems (Eucalyptus grandis Hill ex. Maiden) in two rural properties located in Alegrete County, RS. The traditional pasture system was compared with two other alternative systems, one of them represented by a pasture land converted to homogeneous eucalypt plantation by using two plant densities (2,222 and 1,111 trees.ha-1) and ...
Production, Carbon and Economical Profitability of Pinus elliottii and Eucalypt...
Oliveira, Edilson Batista de; Ribaski, Jorge; Zanetti, Éderson Augusto; Penteado Junior, Joel FerreiraThis work objective was to estimate wood production, CO2 stocks and economical profitability, including carbon credits sale from pasture associated eucalyptus and pine plantations. For each species, two experimental plots were used, all installed at natural pasture land in Alegrete, Rio Grande do Sul State. Experimental plots were submitted to three treatments: two of them with silvipasture systems at triple...
