I don't think you want to get rid of your clover - it fixes nitrogen so feeds the soil without recourse to bagged fertiliser. Great for feeding livestock as it's often higher in protein and mineral content, partcularly calcium, phosphorus, magnesium, copperand cobalt, than grass. Also the nutritive value falls less with age than in grass. Too much can cause bloat though. You also shouldn't feed breeding stock on red clover as it can have high levels of oestrogen-like substances that can affect the breeding cycle.
It's frequently sown with ryegrass and others in a mix. Application sof nitrogenous fertilizer suppresses clover and encourages ryegrass to grow.
