Recommendations:

Recommended pH:6.0. If the pH is less than 6.0, see Lime Table C.
Nitrogen:135-175 pounds nitrogen (N) per acre. Rate will depend upon cropping system.
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.

Piedmont Low: 0 - 120 lbs/acre Medium: 121 - 240 lbs/acre High: >240 lbs/acre
Other:See sulfur (S) and boron (B) recommendations below.

Fact Sheet:

*For canola following a non-legume crop, apply 160 to 175 pounds nitrogen (N) per acre. Following a legume crop, apply 135 to 150 pounds nitrogen per acre. Apply 40 to 50 pounds of the recommended nitrogen per acre in the fall and the remainder in early February prior to crop bolt (rapid stem elongation).

On soils where sulfur deficiency is likely, apply 10 pounds of sulfur (S) per acre with the sidedress nitrogen.

On soils testing low in boron (B), apply 1 pound of boron (B) per acre with the preplant fertilizer.
