Responses of Soil Macrofauna to Variation of Land Use System, Crop Type and Crop Management The effect of land use, crop type and agricultural management on soil macrofauna was investigated with survey of four habitats in Jajarm region of Iran. The habitats included of rangelands, alfalfa fields and low-input and high-input wheat fields with four replicated. Results showed that in rangelands the taxonomic richness, Simpson diversity index and abundance of macrofauna families tremendously were lower than agricultural habitats. In alfalfa fields, higher abundance of key macrofauna than wheat fields was due to use not of chemical inputs, low disturbance and perennial of alfalfa. The kind of crop management had not significant impact on soil macrofauna. Although, key soil macrofauna show great tend to occupancy in low-input wheat fields. The community of soil macrofauna in four habitats and their ecological implications will be discussed.
