Measured 4 quarts (1 gallon) of AGRI-AFC 15-0-15 and it weighed 6 lbs. 14 oz. Therefore, it is a “Course Grain Fertilizer” per the chart below.
- Running in 1H goes 0.7 MPH faster than the 3 MPH cited or about 25% faster so 25% less will be spread. The following reduces the “Quantity to be Spread” by 25%.
- Lever setting 2 = 88-22 = 66 lbs. per acre = 1.5 lbs/1000 SF
- Lever Setting 3 = 206-51 = 155 lbs. per acre = 3.55 lbs/1000 SF
- Lever Setting 4 = 297- 74 = 223 lbs per acre = 5.12 lbs/1000 SF
- Lever Setting 5 = 697-174 = 523 lbs. per acre = 12.0 lbs/1000 SF
- Running in 2H will be accurate for the center row of the Course Grain portion of the chart below.
1/8/2022 – Spread mix of 13-13-13 and Winter Ryegrass in the new little pond yard. Setting above did not discharge enough so had to increase it 50% and should have been a little more. Likely due to the seed mixed in made it flow slower????
