A study was installed from 2000 to 2002 in two recently thinned slash pine stands in the flatwoods region of southeastern Georgia to investigate growth response to various single midrotation vegetation control via herbicide and/or NPK fertilization and/or lime. Stand growth along with soil and foliage nutrients were assessed annually ...

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 ...

Japanese beetle is an invasive insect with a host range of over 300 plant species and known pest on turf, ornamentals, fruit crops, and field crops. It has established across the eastern US and found as scattered reports in the western US. Report observations to EDDMapS (website or app) to help track ...

Some invasive plants have sticky or spiny seeds that can hitchhike on clothing, shoes, and gear.

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 ...

Imidacloprid is an insecticide commonly used for hemlock woolly adelgid management. The Environmental Protection Agency (EPA) has recently released new aquatic endpoints. Often these numbers are misunderstood by the public. The purpose of this document is to provide guidance to federal and state employees, as well as concerned citizens, on ...

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 [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 ...

In many areas of the US, Iron Deficiency Chlorosis (IDC) is a common limiting factor for soybean yields. Dr. Ana Carcedo at North Dakota State University explains the causes and management options for farms with IDC.

This is the second webinar in the two-part series, Soybean Resilience Blueprint: Adapting to Climate, Cost, and Change. This webinar features Dr. Paul Mitchell, Dr. Shawn Conley, Dr. Seth Naeve, Dr. Nicole Fiorellino, and Dr. Michael Plumblee. Topics include an overview of the current economic projections in soybean and what ...

Planting soybeans faster could make it easier to meet the optimal planting window for your state. Dr. Mike Mulvaney from Mississippi State University explains the importance of early planting and the current research on different planting speeds.

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 ...

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

Biological or biostimulant seed treatments are growing in popularity and often advertise promising results for crop growth, function, and yield. The Science for Success team wanted to test several commercially available products across a wide array of field environments to see how things played out in the real world.

Understanding soybean nitrogen (N) nutrition is key to producing high-yielding soybean crops. Dr. Nicolas Cafaro La Menza from the University of Nebraska explains soybean N requirements and how to overcome a nitrogen limitation.
