| Abstract | ||
| Laboratory study was conducted to show the Role of phosphogypsum on leaching efficiency for soils different in salinity type and texture using saline and River water .The experiment content three treatments soil texture ( clay loam and sandy loam ), type of soil salinity ( saline and sodic saline) and phosphogypsum levels (0,9,18 T.H-1). The soil were sieved by 2mm diameter size and packed in plastic columns of 120 cm length and 10 cm diameter. .The experiment was factorial in a complete randomized design(CRD) with three replicates using Leaching continuous method in the first stage was used saline water 8.3 ds.m-1 and then using river water 1.0 ds.m-1 in the second stage .soil columb was cutted before leaching cutting to four parts 0-20 , 20-40,40-60,60-80cm. The result showed that Soil texture caused a significantly effect on ECand SAR The which showed that the high mean in clay loam soil while the low mean was in sandy loam this decreased was 33.17%,57.3%,was respectively . Type Quality of soil salinity caused a significant effect on EC, and SAR ,the high values were in saline sodic of soil compared with saline soil significant decrease was4.2% and 67.6% respectively. Addition of phosphogypsum levels showed significantly effected on Ece ,SAR and PH high addition( 18 T.H-1) of phosphogypsum compared with control (0 T.H-1) caused asignificantly increase on Ece was 7.5% and caused significantly decrease pH and SAR ( 5.6% , 52.3% )respectively | ||
