19-19-19 Starter- All Mineral Stock Fertilizer
50 lb. Bag which covers 10,000-12,000 sq. ft., which is roughly a quarter (1/4) acre.
For Fertilizing- Take half the highest setting, and subtract one or two.
Most of our fertilizer bags will tell you to spread 4-5 lbs. of material per 1,000 sq. ft., and this formula will work for almost any broadcast spreader- Half of highest setting minus 1 or 2
Example: If the highest setting on your spreader is 20, then set your spreader at 8 or 9to spread fertilizer.
