Abstract: Soil fauna play important roles in soil processes, e.g., organic matter decomposition, nutrient mineralization, and redistribution. Studies on the effect of fertilizer application on soil fauna community are useful in guiding our understanding about the effect of fertilizer application on the process and mechanisms of soil ecosystems. We used data assimilation to examine the impact of fertilizer application(organic fertilizer, inorganic fertilizer, inorganic fertilizer with organic fertilizer or straw)on the abundance of earthworm, mircroarthropod(Collembola and Acari)and nematode and diversity of soil fauna. Studies of the effect of fertilizer application on soil fauna community were mainly conducted in agricultural ecosystems, but less in forest ecosystems. The effect of fertilizer application generally showed positive, negative, and no significant effects on soil fauna abundance(earthworm, Collembola, Acari and nematode, respectively)and diversity. However, significant effect of organic fertilizer application on the abundance of earthworm and collembola and Shannon-Wiener's index of the soil fauna were found. Fertilizer application is among the most important management practices for agricultural and forest ecosystems. Organic fertilizer is preferable to inorganic fertilizer to increase the abundance of soil fauna while promoting ecosystem productivity. It is necessary to further study the effects of fertilizer application on soil fauna community, especially in forest ecosystems.
