Throw it out by the shovel full then lightly rake it about.

A seed spreader could be made to work as could about any fertilizer spreader. You will need to experiment some to find the right settings to do that and you will find that even a light breeze may cover you with that compost as you spread it.

I've spread it using the rolling "box spreader" type when we needed just a light layer over seeds in a flower patch.

You have to be sure it's sifted smaller than the openings, and run a few tests to get the right setting. I rolled on the client's driveway so I could see how much was being spread, then swept it up.

To keep it in place water lightly after you spread.

make sure no seeds in the compost.

Any rental companies around that might rent one of the roller applicators?

I'd lend you mine if you were close. :-)

Spreaders designed for granular stuff (seed and fertilizer) may or may not work on different materials. You just have to try it. I haven't tried compost this way but I did try sifted wood ash in a standard Scott box type spreader once. It was so fine it clumped up around the bottom and stopped coming out in a few minutes.

I don't know why the roller type compost spreaders are so darned expensive. I guess it's a volume thing. If they sold as many as they did fertilizer spreaders, they'd be $99. I'm thinking of building one.
