Microbial activity and metabolic quotient of microbes in soils amended with biochar and contaminated with atrazine and paraquat

Acta Agriculturae Scandinavica, Section B — Soil & Plant Science, 2017
The study was conducted to determine how biochar as a soil amendment maintained the microbial community in pesticide contaminated soils. Alfisol (Adenta series – Typic Kandiustalf) and Vertisol (Akuse series – Typic Calciustert) were amended with biochar (0 t/ha biochar, 10 t/ha cocoa husk biochar (CHB), 10 t/ha rice husk biochar (RHB)) and pesticides (

Paddy soil fertility shifts microbial metabolic quotient by regulating the selective enrichment of specific bacterial groups

Geoderma
The heterogeneous distribution of specific microbial taxa with diverse physiological traits, caused by changes of soil fertility level, controls community-level functions. However, how specific microbial taxa mediate community-level carbon (C) metabolic efficiency across various fertility conditions in paddy soils is limited.

Industrial and urban organic wastes increase soil microbial activity and biomass

Revista Brasileira de Ciência do Solo, 2012
Microbial processes have been used as indicators of soil quality, due to the high sensitivity to small changes in management to evaluate, e.g., the impact of applying organic residues to the soil.

The effect of deforestation and land use change on ecophysiology indices of soil carbon and nitrogen [PDF]

مجله جنگل ایران, 2015
Carbon dioxide, methane and nitrous oxide are the most important greenhouse gases. The changes of these gases are mainly affected by the variability of carbon and nitrogen ecophysiology indices.

Asymptotic analysis of noisy fitness maximization, applied to metabolism and growth

, 2016
We consider a population dynamics model coupling cell growth to a diffusion in the space of metabolic phenotypes as it can be obtained from realistic constraints-based modelling.

Effect of a radioactive waste of oil-producing complex on microbial community of gray forest soil

RUDN Journal of Ecology and Life Safety, 2011
In the laboratory-scale experiment effects of the wastes containing oil components and elements of natural radioactive families U238, Th232 and K40, on a microbial biomass, soil respiration, metabolic quotient, dehydrogenase activity and number of ...

Seasonal variations in soil characteristics control microbial respiration and carbon use under tree plantations in the middle gangetic region

Heliyon
Seasonal variations directly impact the biochemical and microbial properties of the soil, influence carbon and nutrient cycling within the soil system. Soils under tree plantation (TP) are rich in organic matter and microbial population, making them more

Factors affecting ammonium uptake in streams - an inter-biome perspective [PDF]

, 2003
The Lotic Intersite Nitrogen experiment (LINX) was a coordinated study of the relationships between North American biomes and factors governing ammonium uptake in streams. Our objective was to relate inter-biome variability of ammonium uptake to physical,
