Microbial, chemical and geotechnical characteristics of tropical heterogeneous soil. Author(s): OSTERREICHER-CUNHA, P.; VARGAS JUNIOR, E. do A.; ANTUNES, F. dos S.; GUIMARÃES, J. R. D.; COUTINHO, H. L. da C. Despite the presence of relevant biomass in the subsurface, soil microbiology has traditionally focused on superficial soils, where plant roots grow and microorganisms thrive, because of the importanc... ... Repository: BDPA Publication year: 2009
Soil structure and its influence on microbial biomass. Author(s): SILVA, A. P. da; BABUJIA, L. C.; FRANCHINI, J. C.; RALISCH, R.; HUNGRIA, M.; GUIMARÃES, M. de F. Soil and crop management have a fundamental role in the maintenance and improvement of soil quality, as they have a direct influence its structure and on microorganisms habitats. The aim of this study... ... Repository: BDPA Publication year: 2015
Soil carbon and microbial processes in agriculture ecosystem. Author(s): SAITO, M.; NOVOTNY, E. H.; CHEN, Y. As global warming progresses, concerns also arise regarding the decline in agricultural productivity and soil degradation. On the other hand, the demand for food is increasing as the population grows,... ... Repository: BDPA Publication year: 2023
Soil fertility, mineral nitrogen and microbial biomass in upland soils of the Central Amazon under different plant covers. Author(s): MOREIRA, A.; FAGERIA, N. K. Amazon is the largest State of Brazil and major area of the State is covered by a largest tropical rainforest of the world. Most soils of the Amazon region soils are characterized as acidic and infert... ... Repository: BDPA Publication year: 2009
Short-term effect of Eucalyptus plantations on soil microbial communities and soil-atmosphere methane and nitrous oxide exchange. Author(s): CUER, C. A.; RODRIGUES, R. de A. R.; BALIEIRO, F. de C.; JESUS, J.; SILVA, E. P.; ALVES, B. J. R.; RACHID, C. T. C. C. Soil greenhouse gas (GHG) emissions are a significant environmental problem resulting from microbially-mediated nitrogen (N) and carbon (C) cycling. This study aimed to investigate the impact of Eucal... ... Repository: BDPA Publication year: 2018
Shifts in microbial and physicochemical parameters associated with increasing soil quality in a tropical Ultisol under high seasonal variation. Author(s): LOPES, L. D.; FONTES JUNIOR, R. C.; PACHECO, E. P.; FERNANDES, M. F. Combination of conservation agricultural practices such as reduced tillage and complex cropping systems can improve soil quality. However, the different effects of conservation practices on soil physi... ... Repository: BDPA Publication year: 2021
Microbial activity in soil cultivated with sugarcane: effect of the amount of straw retained in the soil. Author(s): VIEIRA, R. F.; PAZIANOTTO, R. A. A. Sugarcane cultivation has gone through intense changes in the management practices due to the introduction of mechanical harvesting and the possibility of using nitrogen fixing bacteria (NFB). The use... ... Repository: BDPA Publication year: 2017
Agricultural management systems affect on physical, chemical and microbial soil properties. Author(s): LOURENTE, E. R. P.; SILVA, E. F. da; MERCANTE, F. M.; SERRA, A. P.; PEIXOTO, P. P. P.; FERREIRA, R. C. F.; ENSINAS, S. C.; NETO NETO, A. L.; ALOVISI, A. M. T.; MARCHETTI, M. E.; CORTEZ, J. W. The purpose of this research was to assess the effects of replacement of native ?Cerrado? vegetation (NV) into croplands on soil chemical, physical and microbial properties. This research was carried... ... Repository: BDPA Publication year: 2016
Microbial biomass and enzyme activity of soil under clonal rubber tree plantations. Author(s): DINIZ, A. R.; SILVA, C. F. da; PEREIRA, M. G.; BALIEIRO, F. de C.; SILVA, E. V. da; SANTOS, F. M. dos Our study aimed to evaluate the influence of rubber tree plantations (Clones IAN 873 and FX 3864) on microbial activity, total organic carbon (TOC), and soils chemical attributes, using as reference p... ... Repository: BDPA Publication year: 2020
Soil microbial sensitivity to temperature remains unchanged despite community compositional shifts along geothermal gradients. Author(s): MOINET, G. Y. K.; DHAMI, M. K.; HUNT, J. E.; PODOLYAN, A.; LIÁNG, L. L.; SCHIPPER, L. A.; NUÑEZ, J.; NASCENTE, A. S.; MILLARD, P. Climate warming may be exacerbated if rising temperatures stimulate losses of soil carbon to the atmosphere. The direction and magnitude of this carbon-climate feedback are uncertain, largely due to l... ... Repository: BDPA Publication year: 2021
