To put on the 160 lb of required Potassium you'll need to apply 1600 lb. of 10-10-10. That will mean over applying 80 lb. of Phosphorus and 160 lb. of Nitrogen. Some Nitrogen is good as a seed starter but the excess helps the grass more than the clover. You'd be closer to recommendations using a fertilizer with higher P & K numbers and a lower first (N) number.
