According to this news article

the next attempt at a booster landing on a barge will be
“SpaceX’s next resupply mission to the space station is due for liftoff April 8. Its launch profile will be identical to the Jan. 10 launch in which the Falcon 9 booster first attempted a shipboard landing, ending with a crash after the rocket ran out of hydraulic fluid to move its aerodynamic grid fins.
SpaceX plans to move its booster recovery operations to landing pads on the coast when the larger Falcon Heavy rocket begins flying. Its first launch is scheduled for no earlier than the third quarter of 2015 from launch pad 39A at the Kennedy Space Center in Florida.
Air Force and Federal Aviation Administration safety regulators must approve the land touchdowns once SpaceX wrings out the process at sea.”
Ok thanks.
