Abstract:
The algal communities of cultivated land, reclaimed desert and waste land in relation to physico-chemical characters were followed during the study period (1996-1997). Organic carbon, ammonia-N and Phosphate levels of soil samples are the major controlling factors affecting algal growth and distribution of algae in these sites. Also, the diversity of algal species was strongly affected by vegetation seasons. The decrease number of algae in the waste land compared to other soil samples may be due to high salinity of this soil. A positive correlation of algal abundance and diversity (mainly diatoms and green algae) during succession with levels of PO4-P was observed in reclaimed desert. Blue-green algae were more dominant in the cultivated soil and waste soil than in reclaimed desert.
