This project includes efforts to maintain, enrich, and characterize Embrapa's forest speciesgermplasm banks. Embrapa has an extensive network of germplasm for forest species, bothexotic and native, which has strategic value for the present and the future. These species wereprioritized for comprising germplasm banks maintained in the field for decades, in many casesexclusive material with strategic importance to society. Although this genetic material plays animportant role in leveraging improvem

Biochar is a carbon-rich material that is distinct from charcoal and other similar materials dueto its use as a soil conditioner to improve soil quality. One factor limiting understanding andvalidation of biochar as a soil conditioner and carbon sink is the lack of long-duration studies inthe field. Such studies are essential, since biochar can be produced from a wide variety of rawmaterials and thermic processes, leading to very diverse products. Most studies are done ingreenhouses; due to cost

Psyllids are small jumping insects in the superfamily Psylloidea (Hemiptera) which damage tovarious agricultural and forest crops. Some psyllids can transmit bacterial diseases to plants:the Asian citrus psyllid (Diaphorina Citra Kuwayama) transmits Huanglongbing disease (citrusgreening), currently considered the most serious citrus disease in Asia and America. There arean estimated 1000 psyllid species in Brazil, but approximately 90% have not yet beendescribed; as of 2012, only 73 species had

The west of Paraná state produces large volumes of grains due to the availability of land well-suited for agriculture. Alongside significant grain production in the region, there are alsoproduction chains for pork, poultry, and fish, and collaborative efforts between producers,cooperatives, agroindustry, and rural extension. Grain and animal protein production createsmajor demand for forest biomass to dry grains, fire boilers in plants, heat poultry sheds, andother agribusiness activities that r ...

The bronze bug (Thaumastocoris peregrinus) is a sap-sucking insect that was introduced inBrazil in 2008, and causes significant losses in eucalyptus plantations. This pest can bebiologically controlled by releasing the parasitoid Cleruchoides noackae, which is native toAustralia and was introduced in Brazil in 2012. Although this parasitoid is being established inmany places, bronze bug outbreaks continue to be variable and severe. This project is intendedto minimize this situation by boosting t

According to data from the IPCC (2007), agriculture is one of the economic sectors accountingfor the most greenhouse gas emissions. Conventional nitrogen-based fertilizers are mostcommonly used in agriculture, and nitrogen is lost very quickly as their componentsdecompose. The generally low efficacy of nitrogen-based fertilizers not only leads to technicaland economic losses, but also contributes to higher concentrations of greenhouse gases in theatmosphere by releasing nitrous oxide (N 2 O), a

This project involves activities and research related to clonal forestry, nutrition, and health foryerba mate involving pest and disease monitoring. These activities involve partnerships withthe Brazilian Yerba Mate Institute (IBRAMATE) and Ervateira Baldo S.A., which provide financialresources, space, labor, and raw materials. Research will be conducted to improve the yerbamate production system in the states of Rio Grande do Sul and Paraná. The objectives are toassess progeny tests and clones ...

Araucaria spp. is a species that can be used to produce wood and pine nuts. Vegetationpropagation techniques to produce Araucaria seedlings via grafting and cuttings/mini-cuttingsand establish orchards to produce wood and pine nuts have been developed and are alreadyunderway at Embrapa Florestas. These techniques are being assessed at a research scale andprotocols need to be tested in rural properties and companies for validation and technologytransfer, as well as to develop and assess improved

Concentrations of greenhouse gases (GHG) in the atmosphere have increased considerably asa result of anthropic activities such as changes in land use, farming, and actions involvingburning fossil fuels. In Brazil, there is considerable action in the global effort to address climatechange, mainly to comply with the international agreements mediated by the United NationsFramework Convention on Climate Change (UNFCCC). Brazil's various commitments includereducing GHG emissions and increasing remova
