Two experiments were carried out in parallel: one under controlled conditions with semi-permanent water tables using lysimeters equipped with oxygen measurers, and the other under conditions of artificially drained plots by continually monitoring their hydraulic functioning. The root system

Research paper thumbnail of Effect of selenite additions on microbial activity and dynamics in three soils incubated under aerobic conditions

Soil Biology and Biochemistry, 2007

The same soil was also incubated for up to 6 weeks, with and without straw and selenite (0–2mg Se kg−1). Changes in microbial activity (oxygen respiration) and dynamics (total, fungal biomass; bacterial density number) were assessed. Selenium fractionation and volatilization were also quantified. Selenium addition had no marked effect on respiratory activity, total and fungal biomass whatever the incubation period, but inhibited the growth of heterotrophic bacteria in the longer term. When straw was added, the same trend was observed with more variability. The volatilization losses of Se differed between soils but did not vary significantly over the 6-week period and were not affected by straw addition. Freshly added Se was more easily extracted than native soil Se and its extractability decreased with time, whereas no change in the fractionation of native Se was observed. This study shows that moderate additions of Se may influence microbial dynamics in aerated soil but could not establish a causal link with changes in Se fractionation.
