1. How to do standard counts: NH3 hose works well for determining populations
of drilled soybeans. A 127 inch length of this hose fastened together at the two ends with a barb,
wooden dowel or duct tape makes a good hoop that can be tossed on the field to determine the population.
Each soybean found within the center fo the hoop represents 5000 plants per acre.
2. A 28" diameter hoop, take the plants counted in the hoop times 10,000. Due to the smaller
sample size take a few more counts with this size hoop.

3. A real hula-hoop can be used to estimate drilled or broadcasted soybean populations.
Randomly throw the hula-hoop in at least five locations in a soybean field and average the results. If you know
the inside diameter of the hoop you can estimate the number of plants per acre.
