Speaking from personal experience at least for my area and my lawns Synthetic N is not necessary EVER but can be beneficial in lowering the annual N expense or may be beneficial during low temperature times. I am not sold that turf quality is better by using synthetic N and in fact may be worse, its a hard call as weather changes from year to year so doing a controlled test is hard.
