1. Cover cropping system and mulching can shape soil microbial status in fruit orchards
ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial gro

2. CARBON DIOXIDE BIOFIXATION BY Chlorella sp. IN A BUBBLE COLUMN REACTOR AT DIFFERENT FLOW RATES AND CO2 CONCENTRATIONS
Abstract CO2 biofixation of the microalgae Chlorella sp. for different CO2 concentrations and gas flow rates in a bubble column reactor has been investigated in this study. Microalgae were cultivated under different CO2 concentrations (at 1.75% and 9.45% v/v) and gas flow rates (at 30, 50 and 70 ml/min). The maximum specific growth rate of Chlorella sp. was

3. Mitigation Of Climate Change Of Coffee Production Systems In Cundinamarca, Colombia
ABSTRACT Production systems with woody perennial plants, ideally timber trees, are technologies accepted in carbon (C) projects to mitigate climate change. This research had as purpose the estimation of C storage and fixation in coffee production systems in Cundinamarca, Colombia. Carbon in biomass, necromass and soil were estimated in coffee plantations wit

4. Photosynthetic gas exchange and antioxidative system in common bean plants infected by Colletotrichum lindemuthianum and supplied with silicon
This study investigated the effects of silicon (Si) on the resistance of common bean plants to anthracnose caused by Colletotrichum lindemuthianum. The plants were grown in a nutrient solution containing 0 (control) or 2 mM Si (+Si) and both photosynthesis and antioxidative metabolism levels were evaluated. The Si concentrations in the leaf tissues of +Si pl

5. Seasonal changes in photosynthesis and water-use efficiency of savanna species and eucalypts in Venezuela
Eucalypt plantations in Venezuela occupy 14% of land covered by savannas. Since water use by plantations in the savannas of Mapire (Venezuelan Llanos) was apparently similar to or lower than in the natural vegetation, evaluating how carbon fixation by plantations compares to the natural vegetation could help to elucidate whether plantations have higher water

6. Physiological and symbiotic diversity of Cupriavidus necator strains isolated from nodules of Leguminosae species
Biological nitrogen fixation, performed by diazotrophic bacteria, plays an important role in the maintenance of agricultural systems, as it contributes with significant amounts of the nitrogen (N) needed for plant growth, totally or partially exempting the use of industrial N fertilisers. Twenty-five bacterial strains isolated from nodules of Leucaena leucoc

7. Estudo da utilização de microalgas e cianobactérias para a captura de dióxido de carbono e produção de matérias-primas de interesse industrial. / Study on the use of microalgae and cyanobacteria for the fixation of carbon dioxide and production of raw materials for industrial applications.
O uso de microalgas e cianobactérias para a produção de biocombustíveis e outros produtos e matérias-primas de interesse comercial tem sido amplamente divulgado como uma tecnologia sustentável bastante promissora, em função das elevadas produtividades areais, potencial para fixação de CO2, uso de terras não adequadas para cultivo e possibilidade d

8. Elephant grass genotypes for bioenergy production by direct biomass combustion.
The objective of this work was to evaluate elephant grass (Pennisetum purpureum Schum.) genotypes for bioenergy production by direct biomass combustion. Five elephant grass genotypes grown in two different soil types, both of low fertility, were evaluated. The experiment was carried out at Embrapa Agrobiologia field station in Seropédica, RJ, Brazil.

9. Utilização das técnicas de ELISA e BIOLOG para estudos de diversidade intra-específica em isolados de Azospirillum amazonense associados a diferentes espécies de brachiaria.
ABSTRACT: This limitation of nitrogen is considered one of the most important factors influencing the Brazilian pastures degradation. However there are evidences that pastures formed by some species of the Brachiaria genus could be benefited by the biological fixation (BNF), guaranteeing a higher longevity to these pastures. Previous studies showed that the

11. Acúmulo de carbono no solo e na biomassa de três espécies arbóreas associadas a fungos micorrízicos arbusculares (FMAs)
Os fungos micorrízicos arbusculares (FMAs) têm papel fundamental no processo de produção de mudas para que as mesmas tornem-se mais tolerantes no processo de transplante, apresentando conseqüentemente maior sobrevivência no campo. Esses benefícios são importantes, tanto no aspecto ambiental, como em projetos de revegetação de florestas fluviais, qu

12. Parâmetros genéticos obtidos por modelos mistos em progênies e procedências da Mimosa scabrella Bentham (bracatinga) / Genetic parameters obtained by mixed models in progenies and provenances of Mimosa scabrella Bentham (bracatinga)
The bracatinga (Mimosa scabrella Bentham) is a leguminous tree naturally occurring in Brazil, between latitudes 21°30S (state of Minas Gerais) and 29°40S (state of Rio Grande do Sul) at low temperatures. Being a perennial tree species, pioneer of rapid growth and meliferous, is commercially used for multiple purposes (sawmill, firewood, coal, construction)
