Hydrothermal processing of biomass and related model compounds [PDF]

, 2012
Future energy supplies, as a result of governmental policy and environmental legislation, will increasingly be borne from renewable sources. Use of biomass to provide fuels and chemicals to replace those derived from coal and oil will be crucial in ...

The nitrogen cycle in the Broadbalk wheat experiment : a model for the turnover of nitrogen through the soil microbial biomass

, 1989
A simple four-compartment model is presented for the turnover of N through the soil microbial biomass, based on measurements made in the Broadbalk Continuous Wheat Experiment at Rothamsted.

Altitudinal patterns of soil and microbial C:N:P stoichiometry in subtropical forests in Daming Mountain, South China

Frontiers in Earth Science
IntroductionAltitude-induced variations in hydrothermal conditions and vegetation affect the carbon (C), nitrogen (N), and phosphorus (P) contents in both soil and microbial biomass.

Seasonal Changes in the Soil Microbiome on Chernozem Soil in Response to Tillage, Fertilization, and Cropping System

Agronomy
Soil microbial communities are crucial for ecosystem services, soil fertility, and the resilience of agroecosystems. This study investigated how long-term (31 years) agronomic practices—tillage, NPK fertilization, and cropping system—along with measured ...

Estimation of microbial biomass based on water-extractable organic matter from air-dried soils from Japanese forests and pasture

Discover Soil
Water-extractable organic matter (WEOM) obtained from air-dried soil samples can be used to estimate microbial biomass instead of chloroform fumigation extraction (CFE) using fresh, moist soils and toxic solvents. However, the accuracy of such WEOM-based

Bacterioplankton community composition and activity in the Atlantic Ocean [PDF]

, 2007
Temporal and spatial patterns of bacterioplankton in six different provinces of the AtlanticOcean were examined between 1996 and 2004. The abundance and integrated biomassof three prokaryote groups (Prochlorococcus spp., Synechococcus spp.

Soil microbial biomass and activity in long-term grassland: Effects of management changes

, 1995
The effects of long-term N fertilizer management history and field drainage on soil microbial biomass N and C and its activity in the surface soil of a poorly-drained pasture soil in S.W. England were examined periodically for 1 year.

A hitchhiker’s guide: estimates of microbial biomass and microbial gene abundance in soil

Biology and Fertility of Soils
AbstractInformation on microbial biomass carbon (MBC) is crucial to assess their stocks and role for plant nutrient release in soil. Next to fumigation-extraction, molecular methods are routinely used to estimate the contribution of fungi, bacteria, and archaea to the soil microbial community.

Cover crop and tillage effects on soil microbial communities in a corn cropping system

Agrosystems, Geosciences & Environment
Soil microbial communities have numerous soil ecological and physiological functions. However, knowledge is lacking on the interaction effects of no‐till and cover crops (CC) practices on these soil health indicators.

Effects of goat manure and inorganic phosphate addition on soil inorganic and microbial biomass phosphorus fractions under laboratory incubation conditions

, 2009
Changes in inorganic phosphorus (P) and soil microbial biomass P following the addition of goat manure and different amounts of inorganic P to an Umbric Ferralsol were assessed over 12 weeks under laboratory incubation conditions using a sequential ...
