title: The influence of some herbicides on selected groups of microorganisms in loess and sandy soils. II. The effect of nitrification.
abstract: Studies on the effect of herbicides on nitrification in field and laboratory conditions have shown that steady use of these substances in the same field does not exert a significant effect on this process in the soil. The herbicides caused only shortlasting disturbances. Nitrification usually returned to a relative equilibrium in several days after the herbicide application.
