Taking Stand Counts In Solid-Seeded Soybeans

Roll a hula hoop, let it fall, and count the number of plants inside the hoop. Repeat at least eight times at random locations in the field. Multiply the average of all counts taken by the factor below to determine the approximate population per acre.

Hoop Diameter	30”	32”	34”	36”	38”
Multiply by	8,900	7,800	6,900	6,200	5,500

If a hula hoop is not available, make a one-square-yard frame of metal or wire and take counts in a similar manner. The multiplication factor for a square-yard frame is 4,840.
