8 This is a manganese sensitive crop. Apply 10 lbs manganese per acre with the fertilizer when manganese deficiency has been observed in previous years. If manganese deficiency symptoms are confirmed, apply foliar manganese as soon as possible (1 lb manganese per acre) and reapply if symptoms recur.   

33 Reduce nitrogen fertilizer rate by 20 lbs nitrogen per acre for Piedmont soils. (Soil Code 4).

35 When not grazed, apply 30 lbs nitrogen per acre and recommended rate of phosphate and potash at planting. Apply the balance of nitrogen as a top-dress in February. Depending on soil type and residual nitrogen levels, optimal yield response typically occurs at 90 lbs per acre for dryland wheat and 120 lbs per acre for irrigated wheat. When grazed, apply 60 lbs nitrogen per acre in the fall at planting and 60 lbs nitrogen per acre in February. Increase nitrogen rate by 80 to 100 lbs nitrogen per acre for above normal stocking rates.

651 The soil test boron is low, however, this is not a boron sensitive crop, therefore no boron is recommended. (When soil test boron is low)

653 The soil test zinc is low, however, this is not a zinc sensitive crop, therefore no zinc is recommended. (When soil test zinc is low)

If manganese deficiency symptoms are confirmed, apply foliar manganese as soon as possible (1 lb manganese per acre) and reapply if symptoms recur.   

15 When recommended rates of phosphate and potash fertilizer were applied to previous crop, additional phosphate and/or potash may not be needed.
