Abstract

In soybean like other crops, application of inorganic fertilizers lead to decline in the fertility of soil in addition to indirect negative effects on soil organisms. Organic manures increase the soil fertility, and the activities of soil fauna. This study is on the impact of application of organic manures and fertilizers on the relative abundance of soil fauna in soybean. Significant difference in the relative abundance of soil fauna was observed due to varied soil fertility levels. It was observed that the habitats supported seven families of beetles viz., Passalidae, Scarabaeidae, Nitidulidae, Staphylinidae, Tenebrionidae, Curculionidae and Chrysomelidae; and nine ant species along with the mesofauna like Collembola, cryptostigmatids and other Acari (Mesostigmata, Prostigmata and Astigmata). Application of farm yard manure and chemical fertilizer combination treatments led to more relative abundance of fauna than use of fertilizer alone.
