Recommendations:
| Recommended pH: | 6.5 to 7.0. If the pH is less than 6.5, see Lime Table A. | ||||||||
| Nitrogen: | 0 pounds nitrogen (N) per acre | ||||||||
| 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.
| ||||||||
| Other: | See boron (B) and molybdenum (Mo) recommendations below. |
Fact Sheet:
Per 60 pounds of seed, apply 1/4 ounce of molybdenum (2/3 ounce of sodium molybdate) in just enough water to slightly moisten the seed. (CAUTION: DO NOT EXCEED THE RECOMMENDED AMOUNT OF MOLYBDENUM.)
Apply 3 pounds of boron (B) per acre.
Piedmont only:
Gypsum subsoil test: Research has shown significant yield increases to gypsum application on some piedmont and mountain soils with red, acidic subsoils. A subsoil sample must be tested to determine if gypsum is needed. Take samples by removing and discarding the topsoil down to a depth of 15 inches. Collect a subsoil sample from the 15-inch depth from several locations, mix and place in a soil test bag. There is a fee for this special test.
