MICROBIAL BIOMASS MEASUREMENT IN ACIDIC SOIL
Soil Science, 1991The chloroform fumigation-incubation method for estimating soil microbial biomass is applicable to most soils; but, problems are associated with its use with extremely acidic soils and with soils amended with carbonaceous substrates. To evaluate the basis for these difficulties, this project was commenced with the objectives of (a) evaluating the ...

Arylsulfatase Activity of Microbial Biomass in Soils
Soil Science Society of America Journal, 1999Abstract Quantification of the different pools of enzyme activity in soils (intra‐ and extracellular) is desired to assess the contribution of the microbial community to specific enzyme reactions and ecological changes in soils.

Ergosterol and microbial biomass relationship in soil
Biology and Fertility of Soils, 1996Ergosterol and microbial biomass C were measured in 26 arable, 16 grassland and 30 forest soils. The ergosterol content ranged from 0.75 to 12.94 μg g-1 soil. The geometric mean ergosterol content of grassland and forest soils was around 5.5 μg g-1, that of the arable soils 2.14 μg g-1.

Quantifying microbial biomass phosphorus in acid soils
Biology and Fertility of Soils, 2000This study aimed to validate the fumigation-extraction method for measuring microbial biomass P in acid soils. Extractions with the Olsen (0.5 M NaHCO3, pH 8.5) and Bray-1 (0.03 M NH4F–0.025 M HCl) extractants at two soil:solution ratios (1 : 20 and 1 : 4, w/v) were compared using eight acid soils (pH 3.6–5.9).

Influence of macroclimate on soil microbial biomass
Soil Biology and Biochemistry, 1989Soils from 12 agricultural long-term experimental fields located in contrasting climatic regions were used to assess the influence of macroclimate on soil microbial biomass (Cmicr). Cmicr was measured using the substrate-induced respiration technique.

2023
The last two decades soil organic matter research developed rapidly, uncovering a central role of soil microorganisms in the sequestration and storage of soil organic carbon (C), especially through accumulation of their necromass. However, despite strong evidence that the so-called soil microbial carbon pump is an important process, the direct ...

Soil microbial biomass: The eco-physiological approach
Soil Biology and Biochemistry, 2010Abstract In the 1980s ecosystem research projects were implemented world-wide since there was a pressing need to quantify the impacts of anthropogenic pollutants. Soil ecosystem analyses concentrated first on the quantification of the element and energy transfer between pools.

Urease activity of microbial biomass in soils
Soil Biology and Biochemistry, 1999Separation of the diAerent pools of enzyme activity in soils (intra- and extracellular) is needed to assess the contribution of the microbial community to specific enzyme reactions. Microbial biomass C and N were determined by the chloroform fumigation method, and urease activity was assayed at the optimal pH (THAM buAer, pH 9.0) in 10 surface soils ...

The Significance of Soil Microbial Biomass Estimations
2017This chapter discusses the significance of utilizing microbial biomass values for investigating nutrient cycling in disturbed and nondisturbed ecosystems. Most biomass estimations are from temperate zone soils under agricultural cultivation, grassland, or forest.

Soil Microbial Biomass and Activity Estimations in Forest Soils
1992The study of the relationship between the three carbon compartments: soil organic carbon, organic Utter and soil microbial biomass has high priority in recent microbial ecological research. With respect to terrestrial ecosystem analysis studies on carbon input and microbial biomass size have provided a basis for estimating nutrient and energy budgets.
