Soybean Statements:

  1. If fertilizer is recommended:  When planted in 30 inch rows, do not apply fertilizer in contact with the seed.  When planted in 7.5-inch rows, limit seed placed N + K2O to 10 lb/a but do not use urea or UAN.

  2. All Soybeans: Soybeans that have been well inoculated are not likely to respond to additional nitrogen fertilizer.
