The effect of different concentrations of phosphate and nitrate and soil extracted on the isolated growth isolation of Scendesmus acutus which is isolated from some local aquatic areas has tested in this research, the number of cells and growth range and duplicated time of all algal cultures among thirty five days has counted. The highest growth range was 3.90 by using a mixture of the three solutions in concentrations (1g/l nitrate + 0.05g/l phosphate + 10 ml / 100 of soil solution), the numbers of cells reached to 8861.11 in the twenty fourth day of culture, and in the lowest duplicated time 10.85, whereas the highest growth range was by using soil solution alone 2.86 and the lowest duplicated time 2.13 at concentration 16/100ml, whereas the growth range decreased and duplicated time increased by using nitrate and phosphate solution all by its own, while the highest growth range reached to 2.13 and 1.76 and lowest duplicated time 3.39 and 4.11 in order.
