Soybean Lodging

scouted Oct. 3, 2023

Soybeans were scouted at the R6-8 growth stage and plants tangled in each other were observed. Many plants were also observed to be laid down to the ground. These were soybeans planted in research plots and these observations were noted across many different maturity groups and planting dates, ranging from March to June. It is also worth noting that this environment experienced damage from Tropical Storm Ophelia two weeks prior to the scouting date.
This issue was confirmed by an NC State Extension Specialist as Soybean Lodging. Soybean lodging can be caused by strong winds and by water flow across the field. There are two types of yield losses associated with lodging including restriction of maximum physiological development (reduced photosynthesis in more productive leaves) and harvest loss. Harvest loss from lodging can range from 3-10%. It is suggested to closely inspect areas of the field where flooding has occurred. As well as follow the recommended seeding rates for your location and planting date.
