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; if soil test Mg is low and lime is not recommended, apply 25 pounds of Mg/Acre.

Fact Sheet:

*First year vines - apply 0.15 pounds nitrogen (N) per vine divided into 3 applications; 0.05 pounds nitrogen just before growth begins, 0.05 pounds nitrogen in late May, and 0.05 pounds nitrogen in early July. Broadcast evenly over a 2-foot diameter circle.

*Second year vines - double first year rate and diameter of broadcast circle. Apply in 3 applications as done during first year. Broadcast evenly over a 3-foot diameter circle.

*Third year vines - apply 0.2 pounds nitrogen per vine before growth begins in early spring. After fruit set, apply 0.1 pound of nitrogen per vine if a good crop is set. Broadcast evenly under the vines.

*Mature vineyards - apply 0.25 pounds nitrogen per vine in the early spring before growth begins. After fruit set, apply 0.15 pounds of nitrogen per vine. Broadcast evenly under the vines.
