Multivariate analysis of microbial activity and soil organic matter at a forest site subjected to low-level heavy metal contamination
Article Abstract:
Partial least square regression (PLS) was used to analyze the impact of heavy metal pollution on soil quality. Heavy metals have an impact on soil quality but must be viewed in combination with other factors. Factors include the quality of the organic matter and patterns of decomposition. Analysis revealed the contents of Ca, Mn, K and pH were positively correlated with respiration rates. Hg and Pb were negatively correlated with respiration rates.

Kinetics of substrate-induced respiration (SIR) and denitrification: applications to a soil amended with silver
Article Abstract:
A kinetic method can be used to measure the toxic effects silver has on soil microbial biomass. Measurements can be taken on basal respiration rates of growing and nongrowing microorganisms. Measurements can also be taken on potential denitrification activity. Silver concentrated in sewage sludge can have a serious adverse effect on microbial activity.

Kinetics of substrate-induced respiration (SIR): theory
Article Abstract:
An equation can be established to explain substrate-induced respiration (SIR). The equation assumes that adding the respiration rates for growing and nongrowing microorganisms will equal the respiration increase after substrate addition. SIR is an important tool for measuring soil microbial biomass.
