Banana crops require higher amounts of chemical fertilizers to meet the demand of productivity international markets, which represent high costs and can be hazardous to the environment. Plant growth-promoting rhizobacteria can improve the nutrients use efficiency through their bio-chemical abilities, eventually, partially replace chemical fertilizers without reducing productiv-ity. So, this study was aimed to evaluate the agronomic efficiency of several bacterial strains, in combination with levels of N fertilization, on morphophysiological, biochemical, and nutritional characteristics related to the growth of banana seedlings, Prata Ana cultivar. The experiment was conducted in greenhouse in a 6 x 5 factorial scheme with the following factors: (1) inoculation with BR11005, BR11674, BR12137, BR12157 or BR12158, and a treatment without inoculation; and (2) doses of N (0, 50, 100, 150 or 200 mg kg-1 of substrate). Bacterial strains were character-ized with respect to genetical, biochemical and physiological aspects. Ninety days after trans-planting, plant height, pseudostem diameter, number of leaves, total leaf area, root volume, total dry mass, total content of chlorophyll, carotenoids, and proline contents, N concentrations and their use efficiency were evaluated. Only strains BR11005 (Azospirillum baldaniorum) and BR12157 (Bacillus velezensis) showed potential to improve the performance of growth-related morphophysiological traits and N use eficiency. The strains are effective for biological N fixation, potassium, and phosphate solubilization, auxin synthesis, and production of siderophores, and hydrolytic enzymes. The performance of plants treated with these strains exceeded those of fertil-ization with 200 mg kg-1 of N treatment.

Interpreting the geological record of Amazon biomass combustion requires comparing charcoal accumulation rates in various biomes at different time scales. Charcoal accumulation rates, a proxy for palaeofire records, were obtained in sediment cores from Amazon lakes surrounded by several vegetation types and from a reservoirs in an intense land use change region. The records presented in this study were obtained in the following areas i) a reservoirs in Alta Floresta region (northern Mato Grosso State); ii) Lago do Saci (southern Pará State), a lake close to Alta Floresta and located at the southern border of Pará State; iii) a bog in an ecotone area in the Humaitá region (southern Amazonas State); iv) lakes in lateritic iron crust of the Carajás Hills (southeastern Pará State); v) Lago Comprido, a floodplain lake close to the Amazon River and surrounded by tropical rain forest (Monte Alegre, Pará State; vi) Lagoa da Pata in the Morro dos Seis Lagos alkaline complex (São Gabriel da Cachoeira, Amazonas State) and vii) Lago Caracaranã, a secluded lake in the northern Amazon cerrado (Roraima State). The highest charcoal accumulation rates were observed for modern records related to an intense change in land use at Alta Floresta, which had no precedent during the Holocene history of the Amazon. High charcoal accumulation rates that were observed in the Carajás region during low lake level phases in the Amazon in the mid-Holocene were comparable to those at the onset of the human settlement in Alta Floresta region. An increase in charcoal accumulation rate was observed in the late Holocene when the lake level was high, suggesting an interaction between climates and human presence. Low charcoal accumulation rates are typical of modern high rainfall environments, as observed in Lagoa da Pata where the environment is not susceptible to occurrences of wildfires even during relatively drier climatic phases. Low charcoal accumulation rates also exist in the relatively dry cerrado (savanna type) biome even during relatively dry phases in the Caracaranã region where the savanna-type vegetation biomass is lower and thus generates less charcoal particles than forest ecosystems.
