Evolução do uso e valorização do Tachigali vulgaris (Tachi) para produção de biochar na agricultura familiar da Amazônia.

Abstract

The native species Tachigali vulgaris has been conquering space in the market, with different types of use, due to scientific and technological discoveries with emphasis on the production of bioenergy that has been presented as a promising source of biomass for the steel industry, which it has led to studies of alternatives that present productive potential in function of the world energy demand. In the production of charcoal, there is generation of residues that can be used in different ways. Environmental, social, economic and sustainability issues, among others, lead to the need to supply biofertilizers, such as biochar, through the use of residues from the production of charcoal. The objective of this work is to describe the evolution of the use of T. vulgaris and analyze the indicators for its performance as a biochar, considering the yield in charcoal production and a literature review. Thus, in this work, the method of bibliographic survey and field study was adopted with quantification of the yield of the production of charcoal of the Eucalyptus genus in a masonry oven with a cylindrical wall. So, it was concluded that there is a tendency to use the species in different functions, in addition to energy, and that residues from the production of charcoal of Tachigali vulgaris have recommended properties of biochar used in the market. Therefore, it is recommended to carry out future research related to efficiency, productivity increase, performance and the effect of the application of biochar on T. vulgaris charcoal residues for the recovery and improvement of soil quality, increased productivity in plantations, and others.
