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...
متن کاملEvaluation of cement dust effects on soil microbial biomass and chlorophyll content of Triticum aestivum L. and Hordeum vulgare L.
ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...
متن کاملMeasurement of microbial biomass N:C by chloroform fumigation-incubation
Harris, D., Voroney, R. P. and Paul, E. A. 1997. Measurement of microbial biomass N:C by chloroform fumigation-incubation. Can. J. Soil Sci. 77: 507–514. We present a calculation for soil microbial biomass N:C ratio determined from a 10-d incubation following chloroform fumigation. The calculation is based on a mathematical model of the N content of the preand post-fumigation soil microbial bio...
متن کاملEstimation of Microbial Biomass Carbon and Nitrogen in Bangladesh Soils
In order to estimate the microbial biomass content and to quantify the amount of available plant nutrients derived from microbial biornass in Bangladesh soils, biomass-C, -N, and available-N eoptents using samples from 8 soils were measured by applying the chloroform fumigation and drying-rewetting methods, respectively. 1)
متن کاملSoil Microbial Biomass Carbon and Nitrogen in Himalayan Rangeland of Eastern Nepal: A Comparison between Grazed and Non-grazed Rangelands
Soil microbial biomass plays an important role in nutrient transformation in terrestrial ecosystems. Microbial biomass is also an early indicator of changes in total soil organic carbon. Thus, the main objective of this study was to identify and quantify the present status of soil microbial biomass carbon and nitrogen with various management practices in Himalayan rangeland. To meet the aforeme...
