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.
Soybean Plant Stands: Is Replanting Necessary?
Early in the growing season, abiotic (freezing temperatures, hail, flooding, etc.) and biotic (slugs, deer, disease, insects, etc.) factors often reduce soybean plant stands. A soybean field with poor seedling vigor, slow plant growth, and low plant stand often triggers an “I need to fix this” impulse. However, these fields ...
The Soybean Growth Cycle: Important Risks, Management and Misconceptions
The soybean crop needs to encounter various conditions across growth stages to optimize yield. Sensitivity to stress varies across growth stages, resulting in an array of risks, some of which can be mitigated through management. Learn more about risk and management options across important soybean growth stages from emergence through ...
Understanding Green Stem in Soybeans
Green stem in soybeans is when there is delayed or abnormal senescence or maturation in soybean plants. The disorder can be confusing, as the cause is unknown and there are many factors associated with it. This factsheet describes what green stem is, commonly associated factors of green stem, and management ...
Soybean Plant Population Density
Soybean seed costs are about 40% of the variable costs in soybean production, and optimizing seeding rate will help to produce high yields without overspending on variable costs. Generally, soybeans require higher seeding rates and more plants per acre in the Northern United States and in later-planted fields across the ...
Longleaf pine seed source impacts on seedling performance in southern Georgia through age 10-years
Longleaf pine containerized seedlings from eleven different seed sources gathered throughout longleaf pine’s native range were planted at five sites in central and southeastern Georgia. Trees at each site were regularly inventoried through stand age 10-years. Seed source effects were evident after 10-years
