After planting, the effects of saturated or flooded fields can have a severe and potentially long-lasting impact on corn. The degree of the effect depends on the length of saturated conditions and the growth stage of the crop. Following corn emergence, saturated soils inhibit root growth and nutrient uptake due to a lack of oxygen in the soil. In higher organic matter soils, nitrate-nitrogen (N) rapidly converts to N gases and is lost to the atmosphere. As a result, under persistent saturation, corn roots stop functioning and plants turn yellow as photosynthesis slows.

Heavy or persistent rains can lead to saturated soils that can injure or kill a seed, seedling, or growing plant. Saturated
soils have an impaired ability to exchange air between the atmosphere and soil. This deprives the seed or plant tissues
of oxygen required for respiration.
Often, we focus our understanding of soil biology on invasive, harmful pathogens. However, within soils are
numerous beneficial microorganisms vital to crop development. Mycorrhizae fungi make up such a segment of soil
biology, critical to the overall supply of water and nutrients to many crops.
These are the aspects of “planting” will help to mitigate cold and saturated soils following planting.
In this video, Austin Scott takes us on a virtual tour of our Dicamaba in the PRE plot at Beck's PFR. The goal of this study is to evaluate different pre-emerge herbicides that look at utilizing dicamaba as a PRE vs. other residuals.
What options do we have/how can we keep soybean fields clean in non-GMO scenarios?
In the video, field agronomist, Luke Schulte discusses a study we are conducting to evaluate what options we have and what the efficacy is like when we no longer want to use a growth regulator in the POST.

Can you get away with a one-pass herbicide system if you delay cover crop termination? Well, with really good biomass and a product with great residual activity, we think you can!
When it comes to suppressing winter annual weeds, cover crops are on your side.

What are effective ways to control weeds with the Enlist system? Check out this video for more info on your three options when it comes to POST herbicides for ultimate weed control.
2020 was the second year we conducted our Enlist System Study where we evaluate different combinations of herbicides both with an in-season residual and without.

Wondering what the best carrier rate for Enlist One? Check out this video featuring Joe Bolte, PFR Technician/Herbicide Specialist, to learn more about our findings from our 2020 demo plots.
When should you make your POST herbicide applications?
The most important thing to remember is to actively scout your fields and make sure you're spraying when weeds are less than 4 in. tall!
Over the last few years, we've focused on honing in on the Liberty/glyphosate and the tank-mix combo, including things like proper coverage, spray tips. This year, we've also started running surfactants.
This PFR study is designed to evaluate Liberty and glyphosate and their carrier rates. Why is this important? Because one is a contact and one’s systematic herbicide, their coverage requirements are different.
This study looks at both Liberty and glyphosate applications (individual and mixed) testing carrier rates from 10-20 gal./A.
Curious about what impact delayed pre-emergent herbicide applications have on overall plant establishment and weed control?
Going into 2021, a lot of the trait platforms available have Liberty in them. Liberty is a great product that can help control those glyphosate-resistant weeds we've struggled with the past few years.
In this video, Jonathan Perkins discusses our 2020 Tillage Weed Management Study which was set up as a prevent plant scenario stemming from the 2019 season.
What do row width and population have to do with weed control? As it turns out, a lot.
