Speed Planting Soybean
Optimal planting dates are critical to acheiveing high soybean yields, but planting windows can be slim. Planting at higher speeds can help get more acres planted during the ideal windows. This factsheet outlines the benefits of optimal planting and management considerations for planting at higher speeds.

Effect of Hurricane Helene on US soybean production
Hurricane Helene reached Florida's coast on September 26, 2024, resulting in strong winds and heavy rainfall over a four-day period throughout the eastern U.S. The objective of this report is to document the prevalence of damage to soybean production after Hurricane Helene. Hurricane damage to soybean plants was variable depending ...

Understanding green stem in soybeans
Green stem is a term that describes abnormal patterns of maturation in soybean, where the seeds and pods mature fully even though the stems stay green. This diagnostic guide describes the symptoms of green stem, field conditions that may increase green stem risk, and management options for fields with widespread ...

Harvest aid applied at soybean growth stage R7 rarely impacted seed, protein, or oil yield
Soybean harvest can be delayed due to extreme weather events like heavy rainfall. Delayed harvest results in soybean seed losses, which reduces farmer profits. Harvest aids are commercially available products that are applied to plants with the purpose of desiccating the foliage so that harvest can occur earlier. The objective ...

Impact of sulfur and nitrogen fertilization on seed composition of soybean
U.S. soybean (Glycine max [L.] Merr) is an important source of nutrition worldwide, with a 2022 export value of $34.3 billion. Nitrogen (N) and sulfur (S) fertilizer inputs can influence nutritional quality of seed due to their roles in amino acid biosynthesis. However, the role of N and S fertilizers needs ...

Soybean yield response to sulfur and nitrogen additions across diverse U.S. environments
As soybean [Glycine max (L.) Merr.] yields reach record hights, more nutrients are required to maintain these production levels. This study was conducted to evaluate the effect of sulfur (S) and nitrogen (N) on soybean yield in diverse environments across the United States. Results indicated that soil and environmental factors ...

Soybean yield response to nitrogen and sulfur fertilization in the United States: contribution of soil N and N fixation processes
Soybean [Glycine max (L.) Merr.] is the most important legume grown worldwide. The effect of nitrogen (N) and sulfur (S) fertilization on seed yield is commonly studied in the United States (US). However, soybean yield response to fertilization remains inconsistent, partly due to the lack of standardized field designs and ...

Low soybean plant population: Is replanting necessary?
The objectives of this management guide are to (a) address the necessary considerations prior to replanting a soybean field; (b) provide images depicting common early season stressors affecting soybean; and (c) explain the potential yield limitations from early season soybean injuries

Foliar fertilizers rarely increase yield in U.S. soybean
There is interest among farmers and agronomists to test different fertilizer products to improve soybean yield. We tested an array of foliar fertilizers in 46 environments across the United States. The following article outlines the results of our studies conducted independently by Science for Success team members and funded by ...

Soybean Yield Response to Nitrogen (N) and Sulfur (S) Fertilization: Contribution of Soil N and Biological N Fixation Processes
Soybean has a high demand for the nutrients nitrogen (N) and sulfur (S). There is also a demonstrated interaction between these nutrients, where S can help improve plant N utilization. This research summary outlines some of our previous research on soybean yield response to N and S fertilization.
