How it works
Soybean population = (Plants × 43,560) ÷ (Row spacing × Row length)
How to Calculate Soybean Population
Soybean population estimates the number of plants growing per acre.
Count plants in a known row length and scale the count to one acre.
This helps evaluate emergence success and determine replant needs.
FAQ
What is an ideal soybean population?
Most soybean fields perform well between 100,000 and 140,000 plants per acre.
When should soybean stands be evaluated?
After full emergence, typically at V2–V3 growth stages.
Does row spacing affect soybean population?
Yes. Narrow rows often require different target populations.
Is this calculator accurate?
Yes, when counts are taken from representative areas of the field.
