I'm not an expert as far as ground effect goes, but here is my educated guess.

You can bring the plane in at a safe speed for a landing, then just above the ground flare out and keep the plane just above the ground (less than a foot). The ground effect will induce a pitch down effect so you need to feed in a little more elevator. The ground effect will also increase effective lift and allow you to increase your angle of attack, futher increasing your drag and slowing the plane down. As the plane slows the lift will decrease and the plane will descend onto the ground.

Sound reasonable? This is all assuming you can fly the plane well enough to accoumplish the task.
