Soybean Hoop Method
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.
