Correlación de actividades enzimáticas con la respiración basal en suelos cacaoteros del occidente venezolano [PDF]

open access: yesAvances en Química, 2009
Samples of three cocoa soils from the Venezuelan west, discriminated in six samples of Pedregal farm (Tucaní, Mérida State), four samples of San Juan Lagunillas Experimental Station (Mérida State) and six samples of Chama Experimental Station (Zulia ...

Are Chondrocytes Overlying Cam Morphology Suitable for Therapeutic Use?

open access: yesOrthopaedic Journal of Sports Medicine, 2020
Objectives: Cam-type femoroacetabular impingement (FAI) results in extra bone and cartilage on the anterolateral femoral head-neck junction, causing abnormal contact between the femur and the acetabulum. We investigated whether chondrocytes isolated from

Arbuscular mycorrhizal fungi activity in the rhizosphere of tree seedlings subjected to residual herbicides

open access: yesBrazilian Journal of Biology, 2021
Trees occurring on the margins of agricultural areas can mitigate damage from residual herbicides. Rhizospheric microbial activity associated with trees is one of the main remedial capacity indicators.

Ammonia volatization from conventional and stabilized fertilizers, agronomic aspects and microbiological attributes in a Brazilian coffee crop system

open access: yesFrontiers in Plant Science, 2023
We aimed to quantify the N losses through volatilization of the main conventional and stabilized N fertilizers applied in coffee plantations. Additionally, we also assessed microbiological attributes of the soil (microbial biomass carbon (MBC); microbial

Effects of tramadol on respiration and basal metabolism

open access: yes, 2022
Estudiamos la acción del Tramadol (un potente analgésico), en ratones, sobre el centro respiratorio y el metabolismo; como parámetros tomamos el volumen respiratorio minuto y el metabolismo basa!. Encontramos que las variaciones de ambos parámetros guardan estrecha relación y tanto el volumen minuto respiratorio como el metabolismo basal se incrementan

The influence of long-term organic and mineral fertilization on soil organic matter

open access: yesSoil and Water Research, 2008
Parameters evaluating soil organic matter quantity (organic C and N content) and quality (hot water extractable C content, aliphatic compounds, microbial biomass C content, basal respiration activity) were determined in soils differently fertilized (NPK -

Basal Respiration as a Proxy to Understand Spatial Trends in CO2 Emissions in the Moscow Region

open access: yesRUDN Journal of Agronomy and Animal Industries, 2016
Soil respiration (Rs) is an important terrestrial CO2 efflux and receives significant attention at different scale levels. However, the sampling density is limited and global Rs databases are biased towards natural ecosystems. Urbanization is among the most important current land-use trends and its role will likely grow in the future. Urban soils store

Aliphatic compounds, organic C and N and microbial biomass and its activity in long-term field experiment

open access: yesPlant, Soil and Environment, 2005
The content of aliphatic compounds, hydrophobicity index, organic C and N content and the microbial biomass and respiration activity were analysed in soil samples originating from different plots of a long-term field experiment (variants: nil, NPK ...

Positive effects of plant diversity on soil microbial biomass and activity are associated with more root biomass production

open access: yesJournal of Plant Interactions, 2017
This study aims to explore relationships between plant diversity and soil microbial function and the factors that mediate the relationships. Artificial plant communities (1, 2, 4 and 8 species) were established filled with natural and mine tailing soils,

Impact of Olive Saplings and Organic Amendments on Soil Microbial Communities and Effects of Mineral Fertilization

open access: yesFrontiers in Microbiology, 2021
Plant communities and fertilization may have an impact on soil microbiome. Most commercial olive trees are minerally fertilized, while this practice is being replaced by the use of organic amendments.
