13. Effect of biochar, chicken litter and NPK on soil fertility, growth and nutrition of sweet orange Pêra-Rio in with Antropic Soil (Terra Mulata) in the Amazonas / Efeito do uso de biocarvão, cama de frango e NPK na fertilidade do solo, no crescimento e na nutrição da laranjeira "Pêra-Rio" em Latossolo Amarelo com a Antrópico (Terra Mulata) no Amazonas
The Amazonian soil presents mostly low natural fertility, however, patches of dark colored soil have been discovered, and are characterized by intense high fertility called Anthropogenic Dark Earths. Adjacent to these soils, Terra Mulata calls attention to the less dark coloration, lower fertility and higher extensions. The orange Pêra-Rio is an important c

14. A estrutura e composição de comunidades microbianas (Bacteria e Archaea) em fragmentos de carvão pirogênico de Terra Preta de Índio da Amazônia Central / Structure and composition of bacterial communities (Bacteria and Archaea) in fragments of pyrogenic charcoal from Amazonian Dark Earth in the Central Amazon
Amazonian Dark Earth (ADE), also known as Terra Preta de Índio, present tropical A horizon, high pH, important nutrients for plant growth, high pyrogenic charcoal levels and intense biological activity when compared to its soil of origin. Soil microbial community is essential for ecosystem function, which is involved in fundamental processes such as the dec

15. Identificação e quantificação do gene pirrolnitrina (prnD) em Terra Preta Antropogênica da Amazônia por PCR em tempo real / Identification and quantification of pyrrolnitrin gene (prnD) in Anthropogenic Dark Earth by Real-time PCR
Anthropogenic Dark Earth (ADE) is considered one of the world\ s most fertile soils and receives this name because it originated from human action, probably by pre-Columbian populations who lived in these archaeological sites. Because of the common trend in agriculture towards sustainability antibiotic-producing bacteria is an alternative for biocontrol to p

16. Análise integrada do uso e aptidão agrícola dos solos na Amazônia Legal visando o desenvolvimento sustentável
Encroachment of the agricultural frontier over the Brazilian Amazon (Amazônia Legal) forest and savanna (cerrado) areas generates an array of negative environmental impacts, such as deforestation and fires. The conflict between the pressing agricultural front, mainly represented by cattle and soya productions, and the preservation of such forest and cerrado

17. Diversidade funcional em solos de Terra Preta de Índio da Amazônia e carvão pirogênico / Functional diversity in Amazonian Dark Earth soils and black carbon
Solos com horizonte superficial antrópico, conhecidos como Terra Preta Antropogênica (TPA), Terra Preta de Índio (TPI) ou simplesmente Terra Preta, representam um dos mais marcantes registros da antiga ocupação humana na região amazônica, sendo comumente localizados ao longo de rios e interflúvios, ocupando várzeas, elevações marginais adjacentes

18. Density and diversity of diazotrophic bacteria isolated from Amazonian soils using N-free semi-solid media
Non-symbiotic diazotrophic bacteria are amongst the most important functional groups of soil-dwelling microorganisms. These bacteria contribute to plant growth predominantly through biological N2 fixation. Here, we evaluated the density and diversity of non-symbiotic diazotrophic bacteria in soils taken from diverse land use systems (LUS) in Amazonia using n

24. DESENVOLVIMENTO INICIAL DE SANGUE-DE-DRAGÃO (Croton lechleri MÜLL. ARG.) SOB DIFERENTES CLASSES DE SOLOS, CORRETIVOS E NÍVEIS DE LUMINOSIDADE NA AMAZÔNIA CENTRAL / DESENVOLVIMENTO INICIAL DE SANGUE-DE-DRAGÃO (Croton lechleri MÜLL. ARG.) SOB DIFERENTES CLASSES DE SOLOS, CORRETIVOS E NÍVEIS DE LUMINOSIDADE NA AMAZÔNIA CENTRAL
The specie dragons blood (Croton lechleri) having been calling international attention due the presence of an alkaloid in its latex called taspine known for its antinflammatory, antibiotic and cicatrizing properties, being largely used in the healing of gastric ulcers, diarrhea and different types of viruses. The latex indiscriminated extraction from native
