The aim of this research was to study the activities of urease and alkaline phosphatase in two natural hazel habitats (Makesh and Fandoghlo) and compare their activities in an artificial habitat (Alborz). Soil sampling was done in spring and summer. The activity of urease and alkaline phosphatase was evaluated by enzyme- substrate reaction. The urease and alkaline phosphatase activity was more in spring in three studied habitats. In addition, results indicated the more enzyme activity in Fandoghlo than their activity in Makesh habitat in both season. In other hand, there was a positive relationship between available phosphorous and nitrogen percentage with urease and alkaline phosphatase activity in Fandoghlo habitats.
