Abstract
The aim of this research was studied the (morphological , chemical and biological ) properties for sulfide fountains in Al-Diwaniyah province were include two region , the first was Al-hisayah and the second was Al-khasif.
The soil samples were taken from the side and the center of sulfide fountains and then the water samples were taken from the center of sulfide fountains.
The results were summarized as :
1. The morphological properties were differ between the two regions , the soil color were yellowish brown (10yr 7/6 and 10yr 7/4 ) to side and center soil consequently of Al-hisayah but the Al-khasif were light brown (10yr 6/2 and 10yr 6/4 ) to side and center soil consequently . The distance of sulfide fountains were (350, 45000)m2 to the Al-hisayah and Al-khasif consequently , the water smell has very terrible in Al-hisayah region with algea ,but in Al-khasif region has terrible water with some small fishes .
2. The chemical properties were measured in two regions . the results showed the al-khasif region in the (side and center) were highest than Al-hisayah region properties in Ec , soluble ions , Calicium carbonate , Total Nitrogen and Potassium but the Al-hisayah region were highest than Al-khasif region properties in pH , Organic matter , Total phosphorus . The sulfide water in Al-hisayah region has the highest values the Al-khasif region properties in Ec, soluable ions , total Potassium and phosphorus but the sulfide water in Al-khasif region has a highest values in total nitrogen.
3. The soil texture were differ between the two regions , the Al-hisayah region were silty and silty loam in the side and center consequently of the fountain, but the texture were loame and silt clay loame in side and center consequently in Al-khasif region . The bulk density were proximate among the soils in both regions .
4. The Al-hisayah region soils (side and center) has the highest values than Al-khasif region (side and center) in the bacteria numbers (12.02 , 13.20, 10.20 , 11.20) ×106 cell . gm-1.drysoil-1 consequently and the Al-hisayah region (center ) has the highest values too in fungi numbers (5.00 and 12.00) ×106 cell . gm-1.dry soil consequently but it has the lowest values in the (side) (13.10 and 7.00) ×106 cell . gm-1.drysoil consequently . The Al-khasif sulfide were the highest values in bacteria numbers but it has the lowest values in fungi values .
The cyano water in the Al-hisayah region has the highest values in bacteria and fungi numbers than the sulfide water in both regions 98.80×106 cell . gm-1.drysoil and 13.00×103 cell . gm-1.drysoil consequently. .
