Nematodes enhance plant growth and nutrient uptake under C and N-rich conditions [PDF]

, 2016
The role of soil fauna in crucial ecosystem services such as nutrient cycling remains poorly quantified, mainly because of the overly reductionistic approach adopted in most experimental studies.

The Influence of Selected Meteorological Factors on Microbial Biomass and Mineralization of Two Organic Fertilizers

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2011
A mesocosm study was conducted in order to evaluate the effects of short-term rainfall and temperature variation on soil microbial biomass and bacteria to fungi ratio. In addition, the relation between the decomposition process of two organic fertilizers,

Nitrogen additions and microbial biomass: a meta-analysis of ecosystem studies. [PDF]

, 2008
Nitrogen (N) enrichment is an element of global change that could influence the growth and abundance of many organisms. In this meta-analysis, I synthesized responses of microbial biomass to N additions in 82 published field studies.

Mineralization of nutrients from soil microbial biomass

Mineralization of nutrients from soil microbial biomass, 1982
Soil samples of parabrown earth and chernozem, each having a different amount of microbial biomass, were used to investigate the contribution of microbial cells to the pool of mobile plant nutrients in soils. The quantities of nutrients mobilized in soils which had been dried or fumigated were closely related to the quantities available in freshly ...

Effects of ZnO nanoparticles on microbial biomass and enzyme activity in soils containing cellulose and lignin [PDF]

E3S Web of Conferences, 2020
In order to investigate the effect of ZnO nanoparticles (ZnONPs) on soil ecosystem in soil with added cellulose and lignin, five treatments were set up: cellulose, cellulose + ZnONPs, lignin, lignin + ZnONPs, and no addition.

RESPONSE OF SOIL MICROBIAL BIOMASS TO CeO2 NANOPARTICLES

EQA, 2011
But de ce travail a été d'évaluer l'impact d'une exposition chronique de nanoparticules de CeO2 (NP diamètre compris entre 50 et 150 nm), sur la biomasse microbienne du sol. L'évaluation de l'effet qui peuvent avoir sur la qualité du sol a été expérimentée sur horizons A1 et A2 d'Epileptic Cambisols en utilisant concentrations de 100 ppm avec des ...

Assessment of tillage systems in organic farming: influence of soil structure on microbial biomass. First results [PDF]

, 2007
Soil tillage modifies environmental conditions of soil microorganisms and their ability to release nitrogen. We compare the influence of reduced tillage (RT) and mouldboard ploughing (MP) on the soil microbial functioning in organic farming.

Parallel Electrical Integration of Photo Bio Electrochemical Systems (photo‐BESs): Performance Gains and Load Dependency

Advanced Materials Technologies, EarlyView.
Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.
