I am hoping that someone with more BFO experience answer your question, but I think what you propose should work. If the BFO seed size is similar to wheat, it should be covered. The clover spread on top will work as long as it rains decently. The only thing you may want to do different is to create more soil/seed contact in regards to the clover. This may be more important in fall planted clover then winter broadcast clover.

If you read the label onImperial clover I think they suggest about 3-5 lbs per acre, but I am not sure. So a1 to 1.5 poundsshould be adequate ifthis is true. I have noclue about BFO.
