The purpose of this study was to determine the halophytic forage crops and some microbiological properties i.e. catalase activity, dehydrogenase activity, microbial biomass carbon and basal soil respiration of rhizosphere soils. Halophytic forage crops like Salsola crassa, Salsola dendroides, Cressa cretica, Salsola soda, Alopecurus myosuroides, Prosopis farcta, Alhagi pseudalhagi, Tamarix smyrnensis, Chenopodium album, Chenopodium sp. were widely determined in Harran Plain, Turkey. Rhizosphere soil samples of these crops were collected from rhizosphere of each plant. The rhizosphere soils were analyzed by measuring microbiological properties i.e. basal soil respiration, microorganism population, microbial biomass carbon, catalase and dehydrogenase activities. Basal soil respiration and microbial biomas carbon content of samples were between 10.67-62.3 μg CO2 /g dry soil and 104.47-216.59 μg C/ g dry soil, respectively. Soil basal respiration was obtained highest in the rhizosphere of Salsola soda. Enzyme activities were affected by the rhizosphere soils, depending on the plant species. Catalase activity and dehydrogenase activity were highest in the rhizosphere of Alopecurus myosuroides, 12.3 ml O2 /5g soil and 348.36 μg TPF/ g dry soil, respectively.
