Recommendations:

Recommended pH:6.0. If the pH is less than 6.0, see Lime Table C.
Nitrogen:160 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 grown on sandy soils and following a non-legume crop, apply 160 pounds nitrogen (N) per acre. To improve nitrogen efficiency on these soils, apply nitrogen as follows: 40 pounds nitrogen per acre at planting, 40 pounds nitrogen per acre 45 days after planting, and 80 pounds nitrogen per acre just prior to crop bolt (rapid stem elongation).

For canola following a legume, such as peanuts or soybeans, reduce the amount of nitrogen applied at planting to 20 pounds nitrogen per acre.

On deep sandy soils or where sulfur (S) deficiency is likely, apply 10 pounds of sulfur (S) per acre with the spring nitrogen application.

On soils testing low in boron (B) or on deep sandy soils where boron deficiency is likely, apply 1 pound of boron (B) per acre with the preplant fertilizer.
