Depending on the crop and environmental conditions, agronomists might typically use the 1/1,000th acre method for determining stand density. For example, growers will count every corn plant in a 17.5-feet-length row plant, counting for 30-inch row spacing to obtain an estimate of plants per acre. However, these traditional counting methods cannot give a reliable guarantee about stand rates in the whole field. Typically, growers will sample various areas where damage has occurred. If a grower samples five locations within a 150-acre field using the 1/1,000th acre method, it will only represent 0.003% of the field. This means that growers are forced to make replanting decisions based on extremely limited field data.
