Environmental Factors

Did you know?

Weather is the leading environmental factor that effects soybeans production. Relationships among air temperature, soil water content, and soybean development are complex. It is crucial for all crops to plant in the “optimum” window. For the soybeans that window would be when the soil is above 50 degrees Fahrenheit. The soybeans risk injury if they experience the freezing temperature within the first 24 hours of sowing and the seeds die or become damaged during the germination stage.

The ideal temperature for soybean growth and development is around 86° F. In general, soybeans can tolerate short periods of high temperatures if supplied with adequate moisture. If not the soybeans will experience drought stress and will affect their developmental stages. On the other hand, too much saturation or flooding can reduce the amount of nitrogen in the soybean plant which is crucial for soybean yield potential.
