Not sure what the 80/100 mix is or what your soil tests recommended, but I will assume your ph is good and that you're adding the right amount of P & K, for soybeans or something close to it. We're not harvesting a crop, but both soybeans and clover do well with P&K.
Assuming you get a good crop of soybeans and they don't get wiped out and they last until early October, the soybeans will add "some" nitrogen back in to your soil, so that is a component, you don't need to add. You will still want to add some P&K.
If you have a bad crop and the soybeans are wiped out in June, then adding some nitrogen for the next clover crop, just a little, will help get it started. If you've added lots of P&K to start with (again, I don't know what you're adding), then you might not need to add anything else for the clover crop. It didn't get used and is still there.
Is this going to be a perennial clover crop? If it is, go ahead and add 200 lbs/acre of 0-20-20 and you won't need to add any more till next fall. Take a soil test again in March of 2018 and let it guide you.
