Growing Corn after Corn

I have written on the subject before, so maybe this is review.  Researchers have pretty good evidence that there is a 10% yield drag if you grow corn after corn.  This does not mean that it will occur every year.  It also does not mean that corn after corn is a bad idea.  It just means factor it in.  It also means it is important to do everything right.

• Corn after corn will work best in well drained fields.
• Nitrogen management is critical.  Split applications may be helpful.
• In the row fertilizer may be helpful.
• Control rootworms
• Control weeds
• Scouting is more critical, for disease pressures as will as insects.
• If you had hard to control diseases like Goss's Wilt last year, you should probably rotate away from corn.
