Wondering of anyone can help me with this one. I tried something new to me this year by using a fescue seed blend that was treated with what was explained to me as a liquid starter fertilizer at my supply house. This is my own personal lawn which is fairly shaded so i'm trying to keep an accurate measurement of the nitrogen amounts applied. Is there any formula that someone knows of that can tell me how much nitrogen I put down on this yard? I used 50 lbs of this seed to cover 8,000 sq. ft.
