71 Apply 220 lbs Epsom Salts (magnesium sulfate) per acre or a fertilizer containing magnesium. (When lime is not recommended and soil test magnesium is low)

73 Apply 2,200 lbs gypsum per acre. (When lime is not recommended and soil test calcium is less than 400 lbs calcium per acre)

560 Alternate nitrogen fertilizer application with that of a complete fertilizer, such as 16-4-8, modified to maintain desired growth and color. Fertilize bentgrass in fall, winter, and very early spring months (September through February) and only sparingly in the summer.
