Soybean Plants per Acre
Soybean plant density for common row widths
based on the average number of plants per foot
of row.
Soybean PPA Using The Hoop Method
When taking stand counts in drilled soybeans, you can use the
hoop method. To count plants using a hoop, randomly toss the hoop
and count plants inside the circle. Convert plants per hoop to plants
per acre by multiplying the number of plants by the appropriate
factor.
The 28-inch hoop, with a
multiplication factor of 10,000,
is the easiest to calculate.
Example:
19 plants in the 28-inch circle x 10,000 =
190,000 PPA
Multiplication factors for other size hoops are listed to the right.
