If a player has the disc and calls timeout and put the disc on the ground but discovers that no timeout left for his team. Is it a turnover considering that he released the disc on the ground ?

Not turnover in my opinion.

20.4. If the thrower attempts to call a time-out while play is live and when their team has no remaining time-outs, play is stopped. The marker must add two (2) seconds to the stall count they would have restarted play on before restarting play with a check. If this results in a stall count of ten (10) or above, this is a “stall-out” turnover.

According to the rule, the play is stopped once the person made the timeout call, so not turnover is possible. The play should restart with a check and adding two to the stall.
