With most of our peanuts out of the ground, we’re looking at putting in cover crops with talk of an El Niño year. UGA Extension Soil & Fertilizer specialist Dr. Glenn Harris answers the question: Should we give that cover crop which follows peanuts a nitrogen (N) credit (lower than normal N fertilization) since our peanut harvest was good?
Short answer: No!
UGA Extension recommends 20 to 40 pounds per acre credit to a cover crop after peanuts.
UGA Nitrogen recommendations for Rye, Wheat & Oat fall planting are 20 to 40 pounds per acre at planting following peanuts and another side dress application in February are the standard nitrogen recommendation in Georgia.
