Abstract

Soil classification and development of Homand Range Research Station was the aim of the study, For the task, 40 years old results of the last soil survey were compared to new information collected on 2004. The station located in near Damavand city in the east part of Tehran, is 220 hectares covering by Astragalus (Tra) spp.-Euphorbia spp. Its annual rainfall touches 329 millimeters and the mean annual temperature is 10.5 ºC. Dry season is about 5 months and other month soil has leaching regime. Appearing classic and petrocalsic and also clay covers in the sub horizons and ochric in top horizon show the xeric regime in this area. Soil characteristics were collected from 19 soil profiles studied in detail scale. On the basis of the results and using the Key of Soil Taxonomy (1998) and Soil map of world FAO/Unesco 1989. Soil of the station were put into inceptisols order with xeric moisture regime. Sequence of formation shows that the soils have calcic and petrocalcic horizon formed on tree land types; terraces, gravelly alluvial fans and pediment plain. They classified in typical calcixerepts and Petrocalcic calcixerepts. Finally soils were separate in 4 series and 7 phases in station. The consequences shows that the territories of station have deep to very deep development soil and according to texture, clay loam to heavy clay loam with brown to brown near the yellow. The direct compression between organic carbon and nitrogen data in tow different period shows redaction in amount of organic carbon in most of samples in 2004 in compared with 1969. The average compression between organic carbon and nitrogen in 4 series soil with using t statistic method declared that the differences for organic carbon in tow period was not significant but for nitrogen was significant controversy.
