Agronomy Talk: Green Snap in Corn

Author: Pat Holloway

Green snap, also called brittle snap, is the breakage of a corn plant usually prior to tassel during the rapid growth period of corn from about the V5 (5 visible leaf collars) – R2 (silk).

I Like Big Roots and I Cannot Lie...

Author: Pat Holloway

Bigger roots? Taller plants? Yes please! 

This year, Beck’s PFR team in Iowa is conducting a FurrowJet™ study to test fertilizer placements and rates to find the most effective method for delivering fertilizer to the plant.

Early Corn Planting to Maximize Yields

Author: Pat Holloway

Over the past few decades, we have continued to see a trend toward earlier corn planting to maximize yields. While there is a yield benefit, early planting comes with the additional risk of unpredictable weather.

Don't Cut Your Lime and Fertilizer Applications Just Yet

Author: Pat Holloway

With the current commodity prices, farmers will be looking to cut costs wherever possible. One of those places will likely be lime and fertilizer applications. If your fertilizer and lime applications are one of the
things you are considering cutting, be sure to evaluate your fields closely and be confident that the cuts are being made on fields that are testing high enough in phosphorus and/or potassium.

Three Observations for Harvest

Author: Pat Holloway

As we approach harvest, three critical observations come to mind. First, be sure to note any fields that are showing signs of nutrient deficiencies. Often times, fields are only soil sampled every two or four years. In the case of newly acquired farms, the previous fertility levels may not be well known, so if deficiencies are present, taking soil samples after harvest and fertilizing accordingly can prevent the same deficiencies the next year.

Late Season Stalk Quality

Author: Pat Holloway

By late August, corn is close to completing its lifecycle and is approaching physiological maturity (black layer). During this period there is not much we can do to impact yields, but it is still important to monitor crop
progress. Not only is it important to watch grain moisture after we reach black layer, it is also critical to monitor for development of stalk rot before and after black layer

Green Snap Presence in Iowa

Author: Pat Holloway

Most parts of Iowa experienced conditions that were drier and warmer than usual throughout the month of June. Recently though, we received some much needed rain. Unfortunately, in some instances, these rains were accompanied by high winds and thunderstorms which occurred just prior to corn tasseling in many fields. High winds just prior to tassel can cause green snap (brittle snap) in corn.

Scouting Fields For Insects and Pests

Author: Pat Holloway

July is a critical month for corn and soybeans as both are going through critical reproductive growth stages. It is also a very important time to scout fields for diseases and insects. In 2015, Northern Corn Leaf Blight was very common in many areas, along with Gray Leaf Spot in others

Managing Foliar Diseases

Author: Pat Holloway

Depending on planting dates and growing conditions this year, both corn and soybeans will begin their reproductive growth stages toward the end of June and into July. This is a critical time to manage foliar diseases. Each growing season is unique in the weather patterns we see and ultimately which diseases we need to be most concerned about.

Early Season Stressors

Author: Pat Holloway

Early season growing conditions can be conducive to disease development. This is especially true as corn and soybean planting dates move earlier in the growing season to maximize yields. Early season stresses caused by cool, water-logged soils can lead to increased incidence of diseases.

What's the Best Soybean Planting Date?

Author: Pat Holloway

Does tax deadline time mean it’s time to plant soybeans? Trends over the past couple of decades have shown that farmers continue to plant corn earlier as farm sizes increase and we continue to push for higher yields. On the other hand, farmers often wait to plant soybeans until later in the year. Beck’s 10-year Practical Farm Research (PFR)® data demonstrates that the highest average soybean yields were obtained when planting occurred between April 15 and May 15.
