摘要：Today fertilizer has become essential to modern agriculture to feed the growing population. Chemicalfertilizers are used extensively in modern agriculture, in order to improve crop yield. Urea is the most popular andwidely used dry N fertilizer. The objective of the present study is to characterize the effect of fertilizers on theearthworm. The effects of soil fertilization with inorganic and organic fertilizers on earthworm rearing (populations,biomass, number of cocoons, juveniles etc.) were studied under different doses of the fertilizers for 60 days. Whencompared, marked changes were observed in the activity of Eisenia foetida in both type of fertilizers introduced. Thepresent work indicates towards the deleterious effect of inorganic fertilizers on the survival of earthworm community insoil.
