Step 1:
Use
Chart 1
to estimate the number of LBS/1,000 square feet of coverage
(Example: 20 LB. bag with 10,000 square foot coverage = 2.0 LBS/1,000
square feet)
Step 2:
Find the closest LBS/1,000 square feet in
Chart 2
that you estimated using
Chart 1
(Example: 2.0 LBS/1,000 square feet = Spreader Setting of 13)
Step 3:
Determine the Spread W
idth by evaluating the particle or seed size in
Chart 3
to determine the Spread W
idth between Spread Paths

speed of 2-3mph or the
application rate will change.
All spread widths are determined by particle size and weight.
