Soil microbial biomass and gas-production activity (CO2) in Chernozems of different land use

Effects of elevated atmospheric CO2 on soil microbial biomass, activity, and diversity in a chaparral ecosystem.

This study reports the effects of long-term elevated atmospheric CO2 on root production and microbial activity, biomass, and diversity in a chaparral ecosystem in southern California. The free air CO2 enrichment (FACE) ring was located in a stand dominated by the woody shrub Adenostoma fasciculatum. Between 1995 and 2003, the FACE ring maintained an average daytime atmospheric CO2 concentration...

Evaluation of Microbial Biomass and Soil Carbon as Well as Weed Parameters on Potato Production Affected Different Weed Management

BACKGROUND: Application of plant mulches plays a significant role in development and expansion of sustainable farming systems. OBJECTIVES: Assessment effect of chemical and non-chemical weeds management methods on weeds density and biomass and the properties of soil, including microbial biomass carbon (MBC) and soil organic carbon (SOC) in potato cultivation. ...

Alterations in soil microbial community composition and biomass following agricultural land use change

The effect of agricultural land use change on soil microbial community composition and biomass remains a widely debated topic. Here, we investigated soil microbial community composition and biomass [e.g., bacteria (B), fungi (F), Arbuscular mycorrhizal fungi (AMF) and Actinomycete (ACT)] using phospholipid fatty acids (PLFAs) analysis, and basal microbial respiration in afforested, cropland and...

Regional-Scale Analysis of Soil Microbial Biomass and Soil Basal CO2-Respiration in Northeastern Germany

Soil Microbial Biomass Determination

Basic Idea: The quantity of microbial biomass in a given soil sample is inherently difficult to measure. To some degree, any measurement of microbial biomass is relative – different methodologies or variations in methodologies will yield microbial biomass estimates that are not directly comparable. For this reason, if you want to measure microbial biomass – choose a method and stick with it exa...
