1. AVANÇOS NA PRODUÇÃO E FORMULAÇÃO DE INOCULANTES MICROBIANOS VISANDO UMA AGRICULTURA MAIS SUSTENTÁVEL
The wide application of beneficial microorganisms in agriculture as inoculants to combat pests and diseases and/or to improve soil fertility and the nutrients availability for plants has been considered as an effective and more sustainable alternative than chemical fertilizers and agricultural defensives. However, it is necessary to examine all processing st

2. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

3. In vitro biological activities of silver nanoparticles synthesized from Scedosporium sp. isolated from soil
One of the important fields in nanotechnology is the development of an environment friendly method for the synthesis of nanoparticles. Many approaches show that microorganisms are the most reliable tools for biosynthesis of nanoparticles compared to physical and chemical methods. In our study, fungi have been exploited for extracellular production of metal n

4. Meloidogyne javanica control in lettuce with fertilizers applied isolated or associated with biological product
RESUMO Os nematoides das galhas limitam a produtividade da cultura da alface e o controle eficiente dá-se por meio do manejo integrado, sendo necessárias pesquisas em relação à eficiência de novos produtos para nutrição e controle biológico. Assim, objetivou-se avaliar o efeito de fertilizantes, aplicados isoladamente, ou em associação com produto

5. Microbiological Indicators of Soil Quality Under Native Forests are Influenced by Topographic Factors
Abstract: Several microbiological indicators of soil quality present high sensitivity, but little is known about the influence of topographic factors on them. This work aimed to evaluate variability of biological indicators of soil quality across a hillslope under native forest and the influence of topographic factors on them. Four positions on a hillslope w

6. Free-living diazotrophs drive castor bean nitrogen input in tropical semiarid soils
RESUMO: Existem poucos estudos sobre a diversidade microbiana em solos de mamona no ambiente semiárido tropical. Os produtos de mamona têm sido amplamente utilizados em todo o mundo e justificam a importância comercial da ricinocultura no semiárido nordestino brasileiro. Como não há qualquer tipo de fertilização, ou manutenção de resíduos da cult

7. Torulaspora globosa: rhizosphere yeast promoting lettuce growth on seedlings and under field conditions
RESUMO Micro-organismos promotores de crescimento vegetal (MPCV) auxiliam as plantas pela produção de fitormônios, disponibilização de nutrientes e manutenção da sanidade vegetal. Dentre os MPCV, as leveduras apresentam grande potencial ainda inexplorado. O objetivo deste trabalho foi avaliar a inoculação da levedura rizosférica Torulaspora globos

8. Conversion of ammonium to nitrate and abundance of ammonium-oxidizing-microorganism in Tropical soils with nitrification inhibitor
ABSTRACT The use of nitrification inhibitors (NIs; dicyandiamide - DCD) is an alternative to reduce oxidation of ammonium (NH4+-N) to nitrate (NO3–-N) in the soil, reducing NO3–-N losses from fertilization practices. Based on the hypothesis that DCD reduces conversion of NH4+-N to NO3–-N in tropical soils and inhibits ammonia oxidizing microorganisms (

9. EXOTIC ARBUSCULAR MYCORRHIZAL FUNGI AND NATIVE DARK SEPTATE ENDOPHYTES ON THE INITIAL GROWTH OF Paspalum millegrana GRASS
RESUMO Os fungos micorrízicos arbusculares (FMA) e os endofíticos “dark septate” (DSE) podem promover o incremento da biomassa vegetal, a depender das condições edafoclimáticas e da interação com a planta hospedeira. O objetivo deste trabalho foi avaliar a interação de fungos micorrízicos arbusculares exóticos e fungos endofíticos DSE nativos

10. Impact of agro-farming activities on microbial diversity of acidic red soils in a Camellia Oleifera Forest
ABSTRACT The production of Camellia oleifera (oil tea), typically planted in acidic red soils in southern China, is limited by low soil fertility. Agro-farming is one way to promote soil fertility by increasing organic matter and microbial communities. To understand the impact of agro-farming activity on soil fertility, three types of agro-farming, namely, r

11. Methane emission induced by short-chain organic acids in lowland soil
ABSTRACT Methane (CH4) is the second major greenhouse gas after CO2, exerting a significant influence on the climate and the chemistry of the atmosphere. In lowland soil, acetate and H2/CO2 are the most important precursors of CH4 and formed from organic matter fermentation in an anaerobic environment, giving rise to short-chain organic acids (ethanoic, prop

12. Maize yields and carbon pools in response to poultry litter, rock phosphate and P-solubilizing microorganisms
ABSTRACT: The acid release of phosphates from rock phosphates (RP) and the retention of ammonium by inorganic phosphates have been studied separately in composting; however, there is a gap in the knowledge of combined application of RP with organic residues and microorganisms. The objectives were to evaluate the combined application of fresh poultry litter (
