Abstract

      In the present world where pollutants like chemical fertilizers affect environmental conditions, a kind of organic fertilizer with enough micro and macro elements is very important. African soil is reported by many researchers to be important and having large capacity due to its nutrition materials. The possible effect of variety soils transported through atmosphere besides sunlight and cloud to the chemical and biochemical compositions of Cladophora Glomerata alga is determined for the first time in the scientific world in this study. C. Glomerata is one of the important algae that grow in Iran’s condition; it has a good content of carbohydrates and lipids. In this scientific work, we used soils from Zanzibar (Tansania region east African), Guilan (north of Iran), Tehran (center of Iran) and two type of soils from Zabol and Saravan regions (southeastern of Iran) in a condition simulated like atmospheric ones. The amounts of reduced Fe, Mn, Cu, Zn, pH, Ec, carbohydrate and lipid were examined. Talaghan Dam water and soil were used as our control. We studied the chemical and biochemical composition of C. Glomerata in 5 different feeding conditions, using comparison method. This alga best adapts to Zanzibar, Saravan and Zabol soil feeding conditions as fertilizer compared to other soils.

Key words: Cladophora glomerata, biochemical properties, Iran soils, African soils, feeding condition
