| Abstract | ||
| This study was conducted in a private vineyard in Babylon Province during the growing seasons of 2001 to study the effect of different levels of foam sulfur on some soil chemical characters around vines. Foam sulfur at levels (0,250,500,750,1000,1250 g/vine) was dressed on 25 Febreuary using RCBD design with three replicates (one vine per replicate). The resullts showed that the addition of foam sulfur lead to reduction in soil pH.The peak of pH decrease was after 65 days from the sulfur addition at 750g S /vine where the pH value reached 7.5 at 750 g S/vine, and 7.56 at 500g S/vine, while it was 7.82 at control. Electrical conductivity, sulfate ion concentration were increased with the increasing of sulfur levels with respect to time , the highest value of each was after 4 months from sulfur addition by 3.91dSm" and 430 mg/kg soil at the level of 750 g / vine respectively while were 3.70 dSm" and 311 mg / kg soil in control. | ||
