Recommendations:

Recommended pH:6.0. If the pH is less than 6.0, see Lime Table C.
Nitrogen:120-160 pounds nitrogen (N) per acre
Magnesium:

If soil test Mg level is low and lime is recommended, use dolomitic limestone; if soil test Mg is low and lime is not recommended, apply 25 pounds of Mg/Acre.

Coastal PlainLow: 0 - 60 lbs/acre Medium: 61 - 120 lbs/acre High: >120 lbs/acre
Piedmont Low: 0 - 120 lbs/acre Medium: 121 - 240 lbs/acre High: >240 lbs/acre
Other:See sulfur (S) recommendations below.

Fact Sheet:

*For small grain following a legume apply 120 pounds nitrogen (N) per acre; for small grain following cotton, corn, etc. apply 140 pounds nitrogen per acre; for small grain following grain sorghum apply 160 pounds nitrogen per acre. Apply 20 to 40 pounds of the recommended nitrogen per acre in the fall and the remainder in February.

On deep sandy soils, apply 10 pounds of sulfur (S) per acre. The sulfur should be applied when the topdress nitrogen application is made.
