Effects of tea planting age on soil microbial biomass C:N:P stoichiometry and microbial quotient
Plant, Soil and Environment, 2023 This study aimed to determine the effect of tea planting age on stoichiometric ratios of microbial biomass carbon (MBC), nitrogen (MBN), and phosphorus (MBP) and soil microbial quotient (SMQ, expressed as qMBC, qMBN, and qMBP, respectively).

Survival of the soil microbial biomass at elevated temperatures
Soil Biology and Biochemistry, 1990 Abstract A grassland soil was incubated for 240 days at either 15. 25 or 35°C. Changes in soil microbial biomass were monitored throughout the incubations in three ways: from soil ATP content, by the fumigation-extraction method and by a new version of the fumigation-extraction method in which carbohydrate released by fumigation is measured, rather ...

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,

The adenylate energy charge of the soil microbial biomass
Soil Biology and Biochemistry, 1983 A method was developed for measuring adenosine 5'-triphosphate (ATP), adenosine 5'-diphosphate (ADP) and adenosine 5'-monophosphate (AMP) in soil. All three adenine nucleotides were extracted from soil with a solution of trichloroacetic acid, paraquat and phosphate.

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.

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.
