Abstract

The aim of this work was to study some physiochemical characteristics in
salt affected soils collected from Tawrga and Kasher Ahmed regions. The
study includes determination of pH, water content, organic matter and some
elements content also fungal identification. The obtained results showed that
all soil samples were slightly alkaline in reaction and containing low
concentration of organic matter 0.802 g – 2.824 g. Soil water content ranged from %29.88 to 45.74%. Soil pH ranged between 7.86 to 7.9 with no
appreciable differences between localities. Soil samples differed in their
content of elements. Most tested localities contained high amounts of Cl
compared to normal soil samples. All tested elements recorded high contents in
samples collected from Tawrga. Five genuses belong to five species including
yeasts were identified. The most frequent genus was Yeasts from which high
number of colonies isolates were detected. In addition Aspergillus were
isolated. Aspergillus and Yeasts may be considered one of the resistant fungi to
high soil salinity (NaCI) due to its large colonies numbers isolated from these
areas.
