THE LOOK OF A "FIRED UP" PLANT

AS A SIGN OF LACK OF NITROGEN

AND POTENTIAL YIELD LOSS. MANY

LIKE TO ADD EXTRA NITROGEN TO

MAKE SURE THIS DOES NOT OCCUR.

WE HAVE SEEN THAT DIFFERENT

METHODS OF NITROGEN APPLICA-

TION AND WHEN IT IS APPLIED PLAY

A CRITICAL ROLE IN DETERMINING

THE AMOUNT OF NITROGENACTU-
