Coast = Coastal Plain    Pied = Piedmont, Mountain, and Limestone Valley


Recommended pH:6.0 to 6.5. If the pH is less than 6.0, see Lime Table B.
Nitrogen:Coastal Plain 100-150 pounds nitrogen (N) per acre.

Piedmont, Mountain, Limestone Valley 80-120 pounds nitrogen (N) per acre.


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
Zinc:If the Zn soil test level is low, apply 5 pounds of zinc per acre.
Sulfur:Apply 10 pounds of sulfur (S) per acre.
Boron:Apply 1 pound of boron (B) per acre.

Fact Sheet:

Nitrogen (N) rates will vary depending on rainfall, soil type, irrigation, plant population and method and timing of applications.

For early growth stimulation apply a pop-up fertilizer using 100 to 150 pounds of 10-34-0 or similar material per acre. Apply the fertilizer 2 to 3 inches below the seeds or roots.

Sulfate of potash magnesia may be used to supply a portion of the recommended potash (K2O) and to also supply magnesium (Mg) and sulfur (S).

For more efficient use of fertilizer split the applications, apply one-third to one-half down (banded or incorporated in the bed) and the remainder in 1 to 3 applications. If the fertilizer is broadcast, increase the application rates of phosphate (P2O5) and potash (K2O) 1½ to 2 times.
