Plant species identity and richness influence microbial respiration of soil microorganisms on various functional groups in northeastern Patagonia, Argentina
(MedCrave, 2018-03-20)
Studies on basal soil respiration (i.e., under undisturbed conditions) are very important because they can be used as indirect indicators of the biological activity in those soils; this ecological process is recognized as ...
Soil microbial communities respond to an environmental gradient of grazing intensity in south Patagonia Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2021-01)
Soil microorganisms communities regulate key functions in terrestrial ecosystems and contributes to the formation of stable organic matter and hence climate change mitigation. The structure, diversity and activity of soil ...
Soil Microbial Community-Level Physiological Profiling as Related to Carbon and Nitrogen Availability Under Different Land Uses
(Science Press, 2016-04)
The goal of this work was to assess soil microbial respiration, determined by the assay of community-level physiological profiling in an oxygen-sensitive microplate (O2-CLPP), in response to endogenous C and several ...
Microbial activity effect on aggregate stability after residue addition in a Mollisol and a Vertisol in the Pampas, Argentina
(Elsevier, 2020-12)
Crop residue addition to the soil promotes an increase in microbial activity and, as a consequence, may improve soil aggregate stability. However, this effect may be different in soils with contrasting aggregation agents. ...
Assessment of microbial community function and structure in soil microcosms exposed to glyphosate
(Elsevier Science, 2012-10)
The large scale use of glyphosate to control weeds in transgenic crops and in no-till management systems emphasizes the need to understand its effects on soil microbial communities. The herbicide may change the soil ...
Land cover does not affect microbial and plant response to glyphosate and nitrogen application in the Pampas (Argentina)
(Elsevier Science, 2021-04)
Many complex, natural landscapes have been transformed into simpler agroecosystems by continuous cropping and the application of glyphosate and fertilizers. The current mosaic with different land cover types can harbor ...
A new microtitre plate screening method for evaluating the viability of aerobic respiring bacteria in high surface biofilms
(Wiley Blackwell Publishing, Inc, 2010-09)
Aims: It is difficult to determine the effects of bactericidal compounds against bacteria in a biofilm because classical procedures for determining cell viability require several working days, multiple complicated steps ...
Soil microbial communities under different soybean cropping systems: Characterization of microbial population dynamics, soil microbial activity, microbial biomass, and fatty acid profiles
(Elsevier, 2008-12-05)
This work analyzes the direct effect of soil management practices on soil microbial communities, which may affect soil productivity and sustainability. The experimental design consisted of two tillage treatments: reduced ...
Evaluación de indicadores biológicos en suelos de la región semiárida pampeana central = Evaluation of biological indicators in soils of the central semiarid Pampa region
(Asociación Argentina de Ecología, 2018-04)
En la región semiárida pampeana aún no se han usado indicadores biológicos para valorar cambios en la calidad del suelo relacionados con el uso de la tierra. El objetivo de este trabajo fue caracterizar, evaluar y obtener ...
A calorimetric analysis of soil treated with effective microorganisms
(Elsevier Science, 2013-07)
Effective microorganisms or EM is a consortium of beneficial microorganisms (primarily photosyntheticand lactic acid bacteria, yeast, actinomycetes, and fermenting fungi) that can be applied as inoculants toincrease the ...
