The Azotobacter population in any of the nonirrigated semiarid soils tested was too small to contribute significantly to nitrogen fixation.

The influence of various pesticides on the growth of Azotobacter vinelandii was tested under nitrogen fixing conditions. Growth was stimulated in nearly all cases. The presence of nitrogenase in bacterial extracts was greatly reduced. Inhibition experiments showed that organochlorine compounds have no influence on the reduction of acetylene. Derivatives of 2,4-dinitrophenol inhibit in a specific way. A wide range of pesticides were tested.
