Abstract:
... The effect of Cu on three different microbial endpoints was studied using different Cu sources, in order to check the usefulness of pure Cu salts to estimate the toxicity of commercial Cu fungicides on soil microbes. Cu additions caused similar dose-response curves of substrate induced respiration (SIR) decreases regardless of Cu source, i.e. the use of pure Cu salts to estimate the effect of Cu f ...

Our aim was to evaluate the validity of this concept. Most studies that report ‘positive effects’ of PSM on plant growth have been conducted under controlled conditions, whereas field experiments more frequently fail to demonstrate a positive respo ...

Addition of carbon is a restoration measure that relies on indirect plant–soil relationships by immobilizing soil nitrogen in microbial biomass to manipulate competitive hierarchies between plant species. The aim of ...
