Recommendations:

Recommended pH:6.0 to 6.5. If the pH is less than 6.0, see Lime Table B.
Magnesium:

If soil test Mg level is low and lime is recommended, use dolomitic limestone.

Boron:Apply 0.5 pound of boron (B) per acre in the preplant fertilizer.

Fact Sheet:

Nitrogen

Coarse Textured Soils (sands, loamy sands, sandy loams):
Apply a total of 110-120 pounds nitrogen(N) per acre. Higher rate of N can affect fruit quality. Broadcast 60 pounds nitrogen in the fall prior to bedding. Apply 50-60 pounds nitrogen in the spring through the drip system. Begin applications when vigorous spring growth begins. This is usually early in mid-February in south Georgia and several weeks later in middle Georgia. Apply at a rate equivalent to 0.60 pounds nitrogen per acre per day throughout the flowering and fruiting season. The nitrogen can be injected daily, weekly, or bi-weekly. On very coarse sands daily or weekly is preferable. Nitrogen can be supplied through the drip system using either nitrogen solutions or calcium nitrate (CaNO3).

Heavy Textured Soils (sandy clay loams or heavier):
Apply a total of 80-90 pounds nitrogen per acre. Broadcast 40 pounds nitrogen in the fall prior to bedding. Apply 40-50 pounds nitrogen in the spring through the drip system. Begin applications when vigorous spring growth begins. This is early to mid-February in south Georgia and several weeks later in middle Georgia. Apply at a rate equivalent to 0.50 pounds nitrogen per acre per day throughout the flowering and fruiting season. The nitrogen can be injected daily, weekly, or bi-weekly. Nitrogen can be supplied through the drip system using either nitrogen solutions or calcium nitrate (CaNO3).

Phosphorus and Potassium

All of the phosphorus(P2O5) and potassium (K2O) should be applied in the fall prior to bedding. If a spring application of phosphorus is made apply in one application and limit the application rate to 10 to 15 pounds P2O5 per acre. Recent research shows that all the potassium (K2O) can be applied preplant. If additional potassium is needed it can be injected into the drip system.

Boron

Do not exceed 0.5 pounds boron(B) in the preplant fertilizer application. Base any spring applied boron through the drip system or foliar sprays on leaf analysis.

Sulfur

Sulfur(S) is recommended on sands, loamy sands and sandy loams. Apply 12 pounds of sulfur per acre in the preplant fertilizer or 1 pound sulfur per acre per week for 12 weeks through the drip system. Nitrogen-Sulfur solutions or magnesium sulfate can be used to supply the sulfur.

Plant Analysis

Plants should be monitored throughout the season using plant analysis. Check with your County Agent for sampling procedures.
