Response of Soil Microflora, Microbial Biomass and Some Soil Enzymes to Baythroid (An Insecticide)

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...

Heavy metal Impact on Soil Microbial Biomass , Soil dehydrogenase activity and Soil Respiration rate

The contamination of agricultural soils by heavy metals is a global problem. Soil texture as a biotic factor represents one of the most important factors that influences the distribution of organic matter and ultimately play decisive role in retention of heavy metals in soil ecosystem. The effects of heavy metals on soil microbial processes were investigated. Analytical grade sulphate and chlor...

DIVISION S-3—SOIL BIOLOGY & BIOCHEMISTRY Soil Nitrogen, Microbial Biomass, and Respiration along an Arctic Toposequence

than other regions of the world (Mitchell et al., 1990; Maxwell, 1992). Summer air temperatures in northern To investigate the interactions among mineral N, C availability, Alaska are predicted to increase 3 to 68C over current microbial biomass, and respiration in arctic soils, we sampled soils five times during a growing season from a toposequence on a slope levels, whereas precipitation duri...
