چکیده انگلیسی
Interruption of C/S-supply immediately caused reoxidation of the reduced S-compounds in the pore water. S2â decreased from 31.6 mg lâ1 to 5.6 mg lâ1, S0 totally, and sulphate increased from 2.3 mg lâ1 to 16.8 mg lâ1. Continuous high values of total sulphur during the period without C/S-supply can be explained only by remobilization of deposited reduced sulphur. Continuous decrease of ammonia removal and plant transpiration and increase of the wilted state of the plants stopped immediately and started again when C/S-supply was reactivated. Thus, ammonia removal can be regulated by sulphur balance. The results indicate importance of oxygen release by plants and reoxidation of dissolved and immobilized reduced sulphur related to detoxification inside the rhizosphere.
