Abstract

DAGH and KAVIR are two faces of PALAYA in desert geomorphology. Since Literally there has not been any proper definition of the word KAVIR and DAGH, it is difficult to distinguish between these two types of desert morphology. However the differences between these two features of desert can be explained mainly by the differences appeared in the chemical soil properties between this two formations. As defined, generally the DAGH and KAVIR is the lowest terrain, which formed by streams or drying lakes. When streams or the occasional torrents of water produced by rains move down the mountains, they are heavily loaded with sediment. These streams and run off spread over the gentle slopes and finally accumulate over the extensive area at lowest terrain patterns. As time passes, with on going evaporation of water and depositional processes DAGH and KAVIR are formed. The only distinction between DAGH and KAVIR is the accumulation of precipitated salts in KAVIR formation. Though the aim of this paper is not to distinguish the differences between this two features of desert in details, in fact this paper reports the results of the soil characteristics of four DAGH located in the central desert of Iran, firstly to clarify the distinction between DAGH and KAVIR and secondly investigate the utilization of DAGH for agricultural purposes. The soil analysis of these two features showed that the total dissolved salt was the main distinctive factors between DAGH and KAVIR. DAGH’s soils consist of heavy soil texture and KAVIR's soil was associated with high saline and alkaline salts. In same parts of DAGH areas, farmers use the land for cultivation of different crops and orchards mainly pistachio in the cold desert and date palm in temperate and semi arid zones. The local farmers also practiced reclamation of the DAGH heavy-soil texture with application of sand particles. Sand dune, which spreads extensively over the desert area, is the main source of sand particles. Dune particles analysis also showed that there is no any limitation for pistachio seedlings in terms of sensitivity to soil salinity. Application of coarse sand particles in DAGH areas appeared to be a good technique for utilization of those areas for pistachio plantation.
