Comments

For peanuts apply 0.3 to 0.5 pound B per acre in the fertilizer, gypsum, or disease control spray or dust.

Apply 250 pounds of gypsum at blooming time. (Where calcium is medium and no lime is recommended or calcium is low and lime is recommended.)

Apply 500 pounds of gypsum at blooming time. (Where calcium is low and no lime is recommended.)
