The location of extracellular enzyme activities in soil aggregates can be influenced by slope position. This study aims to determine the effect of slope position on aggregate distribution of organic C and L-glutaminase activity. The soils were collected from different slope positions (shoulder, backslope, footslope and toeslope) at two pasture ecosystems (Fereydoonshahr and Chelgerd, central Iran). A wet sieving procedure was used to separate soil aggregates and then mean weight diameter (MWD) was calculated. Soil organic C (SOC) and L-glutaminase activity (LGL) were measured in the separated aggregates. Results indicated that slope position influenced aggregates distribution and stability through its effect on soil physico-chemical properties. The LGL activity significantly influenced by slope position which was consistent with the pattern of SOC content (Fereydoonsahr: r=0.7, P
