Soil microbial biomass and its controls

Journal of Forestry Research, 2005
Microbial biomass represents a relatively small standing stock of nutrients, compared to soil organic matter, but it can act as a labile source of nutrients for plants, a pathway for incorporation of organic matter into the soil, and a temporary sink for nutrients. This review describes several factors controlling the dynamics of soil microbial biomass.

Evaluation of soil microbial biomass methodology

Toxicological & Environmental Chemistry, 1991
Six methods, used for the determination of soil microbial biomass/activity, were assessed for their sensitivity to distinguish between four varying soils. Of the methods assessed, substrate‐induced respiration (SIR) demonstrated the greatest degree of sensitivity in detecting differences in microbial biomass/activity between the four soils.

Soil microbial biomass—Interpretation and consideration for soil monitoring

Soil Research, 2011
Since 1970, measurement of the soil microbial biomass (SMB) has been widely adopted as a relatively simple means of assessing the impact of environmental and anthropogenic change on soil microorganisms. The SMB is living and dynamic, and its activity is responsible for the regulation of organic matter transformations and associated energy and nutrient ...

Soil microbial biomass estimates in soils contaminated with metals

Soil Biology and Biochemistry, 1986
Abstract The validity of the chloroform fumigation-incubation procedure for measuring soil microbial biomass in field soils contaminated with metals (e.g. Cu, Ni, Zn, Cd) was assessed. The metal contamination was the result of past sewage sludge additions and the contaminated field soils now contain metals at about current maximum U.K.
