Here is your answer

As we know the objects with less density than water will float

In some seeds nutrients won't be there they are dead seeds they won't have nutrients in them they will not be suitable for seeding if sow also they won't germinate

We can sow sunk seeds because they have nutrients in that and they will germinate very well
