Why does everyone still need the spring fert app across the board? Is it just so client thinks he's getting his money's worth?
I must admit I am working in better soils than most anyone else. But I have found that spring fert is only needed in a couple of heavy soil situations, and there it is just a lite app of starter fert. Most of my properties have not had any N application before Memorial Day, about 4-6 weeks after growth initiation and after KBG goes to seed.
Research over the last 20 years has constantly shown that spring N only increases leaf elongation and seedhead production. It does nothing for the overall health of the plant.
