| Abstract | ||||
| The investigation was conducted to find out the fungal diversity, and chemical characteristics of agricultural soils in Sohag governorate, Upper Egypt. Examined soils have mean values of 1.66% organic matter, 0.03% total dissolved salts, 7.02% pH value and 12.8 % moisture content. All agricultural soil samples proved to be contaminated by filamentous fungi. A total of 87 fungal species + 8 varieties of 27 genera were isolated and identified from fifty soil samples on Czapek’s-glucose and potato-dextrose agar media using dilution plate method. The gross fungal count on Czapek’s-glucose was higher 1409649 CFU/g of dry soil, 25 genera & 86 species + 8 species-varieties) than 1212310 CFU/g dry soil, 19 genera & 66 + 6 on potato-dextrose agar media. Aspergillus was the most dominant genus on both media (100 % & 94 % of the samples tested), respectively followed by Mucor, Trichoderma, Fusarium and Talaromyces. On the other hand, Chaetomium herbarum, Cunninghamella spp., Humicola spp., Rhizopus stolonifer and Stachybotrys cartarum appeared on Czapek’s-glucose and completely disappeared on PDA, while Cephalosporium trigonosporum and Rhodtorula mucillignosa appeared in rare on PDA and completely missed on Czapek’s-glucose. Finally, microorganisms especially fungi played an important role in fertility of agricultural soils in this region of Upper Egypt. | ||||
