I don't know what hybrid willows are, but I'm very familiar with willows in general.
They respond very well to being pollarded (whacked off at some height in the end of the dormant season) and put out copious shoots within a month or two, so you wouldn't have to let them grow to full height. We pollard ours in Ladakh every 3 years or so, once they are well established. We cut them at about 7 feet, and they reshoot to like 20 within the same season. Every three years we get a harvest of poles and twigs.
Yeah, if that would be a long line of the same trees, do consider varying it instead and putting in some other things that would give you joy or food or something, not only block the view.
What do you mean by they enhance nitrogen?
