Soybean Foliar Fertilizer Evaluation: What is Working
Presented by: Dr. Jeremy Ross
Extension Agronomist – Soybean Professor, University of Arkansas, Division of Agriculture Cooperative Extension Service
Many soybean producers apply foliar nutrient products during soybean reproductive growth as a routine production practice. These applications are made in addition to the use of commercial fertilizer products applied to the soil. Due to the narrowing of production margins, many have questioned if these foliar nutrient products increase soybean grain yield and are profitable. In 2019 and 2020, Arkansas collaborated with 12 other soybean producing state to compare the soybean grain yield response to six commercially available foliar nutrient products. Results from the two locations in Arkansas showed no significant yield increase with any of the products evaluated compared to the untreated check. From these initial results, using these products as a routine production practice would not be recommended.
Soil Fertility In Soybeans And When, And When Not, To Use Foliar Fertilizer
Presented by: Robb Dedman
Arkansas Consultant: Ultimate Ag Consulting
Dedman has studied the importance of fertility in soybeans as good fertility relates to yield. “There are four things that contribute or fail to contribute to good yields,” he says. “In soybeans, we don’t typically get a good response from foliar type fertilizer.” However, there are times when the opposite is true. He will discuss when to use foliar fertilizer.
His first experience with consulting was when he starting scouting rice while in high school under Dr. Nathan Slaton who was the Extension agent at the time. Dedman holds a bachelor’s degree in agronomy from the University of Arkansas, and presently owns his own ag consulting firm, Ultimate Ag Consulting.

Harvest Management Strategies to Optimize Soybean Yield Potential
Presented by: Dr. Trent Irby
Extension Soybean Specialist, Mississippi State University
Environmental conditions during the latter part of the soybean growing season can present a multitude of challenges. Excessive rain may prevent timely application for disease and insect management, or result in delayed harvest due to poor field conditions. Soybean harvest aids have become common practice across much of the Mid-South and can be used to facilitate a faster, more efficient harvest. Given the environmental conditions that are common during the harvest season, it is important to understand harvest aid performance as well as the impact that delayed harvest may have on soybean yield and grain quality.

Alternative Farming Practices Due To Necessity
Presented by: Brett Stewart
Arkansas Farmer: Soybeans
Necessity has led Brett Stewart to toy with some alternative farming practices. No-till has been a good fit going into soybeans. He has been able to establish good stands and maintain yield going straight no-till into both corn stubble and rice stubble with an ordinary Great Plains drill. Most of his patty rice has been converted to furrow-irrigated rice to take away the challenges that levees present post harvest. Also he has had no trouble drilling furrow-irrigated rice straight into both soybean stubble and corn stubble. No-tilling corn has been more challenging, as stands have been a little too uneven and yields are not where they should be, but there is still a cost savings in both tillage and herbicide applications. “I don’t want to give up on no-tilling corn yet though because I have observed better yields for all crops as we get into the third year of no-till in a particular field,” he says. “Right now I am crediting that to compaction issues in the first and second years following conventional tillage. I am excited to continue these cost-saving and time-saving experiments.”
Stewart farms approximately 2,000 acres total of rice, corn, soybean. Currently, each crop consists of about1/3 of his total acres. Some years he plants about 200 acres of wheat, which is then double cropped to soybeans. A first generation farmer, he started his own operation in 2016 and moved into full-time farming in 2017. This is his fourth crop as a full-time farmer. He did not grow up on a farm, but he admired farmers and their lifestyle. His first experience in agriculture was working in entomology for Dr. Gus Lorenz as a seasonal technician during the summers of 2009, 2010 and 2011.
Reevaluation of Fertilizer Recommendations for Soybean Production in Louisiana
Presented by: Dr. Rasel Parvej, PhD
Assistant Professor & Soil Fertility Specialist, Louisiana State University AgCenter, Scott Research & Extension Center, Macon Ridge Research Station
Most land-grant universities have developed fertilizer-P and K recommendations based on topsoil (0- to 4-, 0- to 6-, or 0- to 8-inch depth) P and K availabilities. Although topsoil-based fertilizer recommendations are fairly accurate for soybean production across a range of soil types, it sometimes gives false positive error i.e., soil-test results indicate a positive yield response to fertilization but in fact it does not occur. This may be due to a small amount of subsoil-P and K availabilities at 6-12-inch or deeper depth that soybean roots can easily access and fulfill both P and K need and resulting in no yield response to added fertilizer. Therefore, both topsoil and subsoil nutrient availabilities need to be considered to develop better fertilizer recommendations for soybean production in Louisiana. We reevaluated soybean yield response to five different fertilizer-P (0, 30, 60, 90, and 120 lb P2O5 acre-1) and K (0, 40, 80, 120, and 160 lb K2O acre-1) rates and two different soil-P and K concentrations from 0- to 6- and 0- to 12-inch depths across 14 sites in Louisiana. The results will be presented in meeting. This study will be continued in 2021 and 2022.
Redbanded Stink Bugs: A Louisiana Perspective and Management Tactics
Presented by: Dr. Sebe Brown
Research & Extension Field Crops Entomologist, LSU AgCenter
Redbanded stink bugs (RBSB) are the most economically important insect pest in Louisiana soybeans. RBSB can outcompete and cause more seed yield and quality losses than native stink bugs. Management tactics utilized by Louisiana agricultural professionals, against RBSB, have constantly evolved since the stink bug’s introduction to Louisiana in 1999. This presentation will address the RBSB’s biology, mechanisms for injury, control tactics and management considerations in Louisiana.
Thoughts and Considerations for the 2021 soybean cropping season
Presented by: Dr. Jason A. Bond
Weed Scientist, Mississippi State University, Delta Research and Extension Center
In Mississippi, soybean production is spread across a large window of planting dates encompassing varying environmental conditions. Challenges to include replant decisions, herbicide options, resistant weed biotypes, and environmental conditions just to name a few make soybean management extremely complex. Therefore, research at the Mississippi State University Delta Research and Extension center was conducted to address some of these challenges in hopes to aide soybean producers.
