What I've always learned is 4 lbs of nitrogen is all a fescue lawn needs per year. And this includes any nitrogen you gain from mulching, side discharging, leaves, etc. If the lawn is not acceptable after 4 lbs of nitrogen a year, then you need to look at when you're fertilizing, watering techniques/schedules, soil structure, soil PH, and lastly Micro nutrients (iron, etc.) Am I off base here? I understand Customer satisfaction drives our industry but when do you say enough is enough and start worrying about our environment we're destroying?
You are right on the money. I deal with soils so bad that 2 lb of N applied at once hardly phases the grass. If grass does not get green and grow like mad on even 1/2 lb of N, more needs to be looked into. Looking into those other things can give you grass that is extremely fertilizer responsive.
