Oat fertilizer guidelines

In Minnesota, the oat crop is used for either grain and straw or as a nurse crop for seeding legumes. The recommendations in the tables that follow are intended for situations where the crop is grown for grain and straw.



Phosphate, potash and other nutrients

The rates listed are appropriate for both broadcast and banded (drill applied) application. There is no research evidence with this crop to suggest that the banded placement is more efficient than a broadcast application.


CAUTION! Do not apply more than 20 lb. N per acre as urea (46-0-0) with the drill. Do not place ammonium thiosulfate (12-0-0- 26) in direct contact with the seed. Do not place fertilizers containing boron in direct contact with the seed.
