Agronomy Talk: Seedling Disease

Author: Alex Long

Any disease requires three things to flourish: a viable host, suitable environmental conditions, and the presence of a pathogen. When we attempt to manage a disease, we must manage one of these three factors in order to be successful.

Agronomy Talk: Terminating a Failed Corn Crop

Author: Austin Scott

There are many reasons a corn crop may fail. In some years it’s a late frost and in others, soil surface crusting. Regardless of the reason the stand fails, it is important to destroy the original crop before replanting. Yield losses can occur if just 5,000 of the original corn plants remain to compete with the new stand. Therefore, it is imperative to successfully eradicate as much of the existing stand as possible.

Agronomy Talk: 10 Reasons Why You Should Stick To Your Planting Plan

Author: Luke Schulte

As the rain is delaying planting, many farmers are becoming concerned that their corn maturities are too long. In my opinion (based on facts), here are the Top 10 reasons why you should stick with your original plan.

Agronomy Talk: Weed Identification and Compaction Issues

Author: Austin Scott

Can you pick a palmer from a redroot? 

Weeds are off to the races this season and the first, and most important step to controlling broadleaf weeds is correct identification.

Agronomy Talk: EARLY CORN DEVELOPMENT

Author: Steve Gauck

When a corn kernel is planted into warm, moist soil, water is absorbed through the seed coat and the kernel begins to swell. The critical soil moisture required for corn to germinate is 30%, and a corn seed will absorb 1.5 to 2 times its weight in water during the germination process.

Agronomy Talk: EARLY-SEASON FLOODING

Author: Steve Gauck

During rainy springs, fields may flood or even stay saturated for long periods of time. Flooded fields have two forms: saturated or waterlogged (where only the roots are flooded) or submerged (where the entire plant is under water). Saturated or waterlogged soils are more common than completely submerged plants, but they can both be damaging to yield.

Agronomy Talk: DELAYED PLANTING

Author: Eric Wilson

In delayed planting situations, there are some key concepts to consider when deciding to whether or not to continue as planned with corn, move to an earlier maturity hybrid, or switch to soybeans altogether.

Agronomy Talk: PFR Proven Fungicides in Wheat

Author: Jim Schwartz

It’s that time of year again. It's the time of year for our wheat to start flowering, so fungicide applications should be top of mind. With the kind of spring we are experiencing throughout much of the Midwest, many factors favor Fusarium head blight (head scab) onset.

Agronomy Talk: Soybean Seeding Rate Considerations for Delayed Planting

Maximizing soybean yield is a simple concept…grow as many harvestable soybeans per acre as possible. What is not so simple is the complex dance we play with Mother Nature who has great influence over the best management decisions required to obtain maximum yields. For multiple years, Beck’s PFR has promoted increasing returns on investment (ROI) by lowering soybean seeding rates.

Agronomy Talk: PURPLE CORN

Author: Dale Viktora

Typically, purple corn leaves are automatically diagnosed as a phosphorus deficiency early in the spring. Although purple corn leaves are a symptom of phosphorus deficiency, this does not always mean there is a soil phosphorus deficiency per se. It could be that the plants are unable to access soil phosphorus due to problems with the root system, excess soil moisture, or cool temperatures.

Agronomy Talk: Delayed Planting Reminders - Stick With Your Plan!

Author: Jim Schwartz

Some areas of our marketing footprint have started planting and are slowly progressing while others have not yet started field operations. Here is some information to review as many of you may have questions regarding delayed planting and switching hybrids.

Agronomy Talk: SULFUR DEFICIENCIES IN CORN

Author: Chad Kalaher

In the past, plant nutrition management was largely focused on nitrogen, phosphorus, potassium, and calcium, since these nutrients are needed in the greatest quantity. Reports and field observations of early-season “striped corn” have become more common across the Midwest over the past decade.

Agronomy Talk: Seed Size and Crop Establishment

For a crop to become established, the seeds must germinate and emerge uniformly. Seed size and shape (also called grade size) is not correlated to germination, vigor, nor yield. If planting conditions are good, all grades have equal quality and the size and health of the embryo within the seed does not change with grade size.

Agronomy Talk: EARLY SOYBEAN GROWTH AND DEVELOPMENT

Author: Denny Cobb

A soybean seed has two distinct parts: the cotyledons and the embryo. The two cotyledons are the main food storage structure, which supply food during emergence and for the seven to ten days after emergence through the V1 growth stage.

Agronomy Update: Southern Illinois Wheat

Earlier this week I scouted some fields in Southern Illinois following the rains we received last weekend. 

With this wheat in this field pushing Feekes 7, I plan on taking some soil and tissue samples in a few different spots to see what's going on in these plants.

Agronomy Talk: SPRING APPLIED ANHYDROUS AMMONIA RISKS

Author: Jim Schwartz

Often, farmers find themselves pressed for time in the spring and are forced into tight windows of operation. One operation that many farmers need to carefully consider is the spring application of anhydrous ammonia. Although it’s possible to apply anhydrous before planting, there are strategies to reduce the risk of injury. Keep in mind that there are many ways to apply nitrogen to a crop in-season, so planting should always take precedence to nitrogen applications. Even if you have pre-paid for your anhydrous, you can still sidedress anhydrous with great success.

Agronomy Talk: SPRING FREEZE DAMAGE TO WINTER WHEAT

Author: Steve Gauck

Cold weather prevents wheat plants from breaking dormancy, so in cold springs, wheat crops may be slow to greenup. Delayed greenup is less concerning than cold damage to the wheat crop.

Chilling injury is only one part of the evaluation of winter wheat in the spring. If the fall was wet and challenging, there could be stand establishment concerns. In some low areas, the seed may have rotted in the fall. If the plant has fewer than three developed leaves going into the winter, it is more prone to injury as the crown is underdeveloped.

Agronomy Talk: Spring Burndown

Author: Luke Schulte

Weed competition at planting can reduce yields. As temperatures start to increase, weeds will flourish, and you will be faced with a short timeline to complete field operations. While it may be tempting to begin planting as soon as possible, it is important to make sure weeds are managed prior to planting. Attempting to control weeds after planting can interfere with your planting operations and create competition with the emerging crop for sunlight, moisture, and nutrients, reducing yields. As weeds continue to grow, they become more difficult to control.

Agronomy Talk: Alfalfa Winterkill

Author: Mike Blaine

The weather we experienced this winter has caused difficulties for everyone, but for farmers, the winter of 2018-2019 has led to uncertainty when in the hopes of a normal spring planting season.

Across a large swath of the Northern Corn Belt, especially those areas where alfalfa is an integral crop, a late, wet Autumn resulted in saturated soils going into the winter months. Compounding this situation were the late December rains (in some locals approaching 2.0 in.), an extremely cold January, persistent low temperatures throughout February and multiple heavy snow events in early March. As of March 13, 2019, when this article was written, Minnesota has experienced our second inch of cold rain.  And though the snow depth has gone from 26 in. to a level of 18 in. in the past 36 hours, the chances of injury to our alfalfa crop is higher than normal this year.
