You can leave the grass grow for aesthetics, to slow golf balls or for environmental reasons but I don't think it does much for keeping geese away. Geese live in marshes so a bit of tall grass does not really matter to them.
In the spring we harass geese constantly with bird bangers and chasing them until they leave. They nest early is we often need to start on them before we open for the season.
In fall for the migratory geese we use fishline around the ponds, milorganite applications, coyote decoys, scarecrows, alligator decoys and we run short random irrigation sets near the ponds to keep the geese uncomfortable at night.
I think geese bring geese so I assume they can smell their own crap and are attracted to areas they have been so its important to keep them away early in the fall.
