Posted on June 15, 2009 by Fred
The hoop method of determining soybean plant population is an accurate method to use for solid seeded soybean fields. By using the table below, the number of plants per acre can be determined by measuring the diameter of the hoop, counting the number of plants that are found within the hoop and multiplying that by the predetermined factor listed. Assess several locations in your field to determine the average number of plants found in the hoop.
