At least you have a start, that's the good news. You can still do a soil test later. but for now, as the different seeds sprout, pay special attention to the clovers. If they can't seem to compete with the grains that may mean that you may need more lime. Even a bag or two of pelletized lime will help the plot out. Most soils will be on the low side, and it takes a lot of lime to make it go too far. Even if the clovers don't flourish, you still have the grains to give you a fair hunting plot. Good luck.
