A review on the effect of herbicides on the earthworms

Author(s): Krishan Kumar, Pooja Kumawat
Abstract: The herbicides, used to fight against the weeds in the agriculture are very toxic to soil biota. To some extent, these herbicides are unrestrainedly used by farmers without considering the long or short term effects in soil medium. It is evident that most of these herbicides may cause the reduction of sensitive populations of certain groups of biota in soil medium. It is believe that in cases where these herbicides are used to treat soils, they are considered harmful to nematode, earthworms and other biological organisms. Studies on this aspect are important because earthworms are the common prey of many terrestrial vertebrate species such as birds and small mammals, and thus they play a key role in the biomagnifications process of several soil pollutants. It is now emphasized that, whereas higher concentrations of a pollutant can easily be assessed with the acute (mortality) test, contaminated soils with lower pollutant concentrations require more sensitive test methods such as reproduction test in their risk assessment. The aim of this paper was to provide a synopsis review of the effects of some herbicides to soil biological community.
