Now is a great time to assess how well crops emerged. Determining the plant population for corn and soybeans at this time of year will allow you to evaluate management decisions made at planting, as well as identify any emerging concerns from weeds, insects or diseases.
When estimating the population:
- Measure 1/1,000 of an acre. See table below.
- Count the number of plants in the measured area.
- Count at least six representative places across the field.
- Multiply the average number of plants by 1,000 to calculate the final plant population per acre.
