Planting is well underway in the Hoegemeyer footprint and we have corn anywhere from seven leaves or more in Oklahoma to seed that still needs to get in the ground. I have been travelling and looking at fields over the last two weeks across Nebraska, Kansas, Missouri and South Dakota. All areas have had one thing in common — an abundance of moisture. In fields where water could drain, we are seeing some excellent stands in our Hoegemeyer products. In areas where water ponded and low lying fields are the fields where we are seeing some stand issues. Also, some fields planted on Friday, April 15, and Saturday, April 16, seems to be suffering from imbibitional chilling injury. Most of the Hoegemeyer footprint received substantial rain on Sunday, April 17, causing cold and saturated soils. These cold, saturated conditions have caused plants in several fields to leaf out underground resulting in stand loss. Aside from a few stand issues, the 2016 crop just needs a little heat and sunshine, and it will be off to the races. Now is the time to be scouting your fields for stand establishment issues to make sure to set yourself up for a successful harvest. If you have any questions or issues, contact your local Hoegemeyer DSM or Agronomist.
I don’t know about you, but spring planting season is probably the part of the job I enjoy the most. As we move from winter into spring and it starts to green up, getting out in the field again is always a great feeling. So far, the spring of 2016 has brought above average temperatures and the majority of March has felt more like April aside from a few snow events. With these warm temperatures, producers may be thinking about getting the planters rolling a bit early. Here are a few considerations and watch outs for spring planting.
Soil Temperature @ 50 Degrees: A good rule of thumb for when to start planting corn is when soils reach an average soil temperature of 50 ͦ or above every morning at 7:00 A.M. for a week. When soils are cooler than 50 ͦ typically emergence will be delayed for a few weeks. The longer the seed sits in cold soils the more potential there is for exposure to pathogens, reducing the chance of germination.
Imbibitional chilling: Imbibitional chilling occurs when seed is planted, begins to germinate and then the soil temperature drops below 50⁰. This will typically happen if seeds are planted into soil above 50 ͦ and then we catch a cold rain, freezing rain or a snow storm that brings to soils temperature down. Imbibitional chilling causes cells to rupture leading to corkscrewing of the mesocotyl. This can either delay emergence or possibly inhibit emergence if the coleoptile can’t get through the soil surface. Other symptoms of imbibitional chilling include aborted radicles, proliferation of seminal roots, delayed seedling growth and potential for diseases pathogens to attack the young seedling.
Sidewall compaction: Planting into fields that are too wet will typically cause sidewall compaction. Even waiting an additional 24 to 48 hours can reduce the potential for sidewall compaction. Remember we only get one chance to plant most fields so waiting for soils to dry out can make a big difference in a fields yield potential.
Planting season only comes once a year and there is nothing more important for setting ourselves up for maximum yields than getting a good even stand on all of our acres. Waiting until soils are fit to plant, waiting to start planting until soil temperatures are sufficient, and delaying planting if the forecast calls for cool wet weather are all good tips to avoid early season problems in our fields.

High pH soils are common in the Hoegemeyer footprint. At Hoegemeyer, we recognize that certain hybrids perform better in these challenging soil types. That is why we ramped up our testing program to evaluate our products tolerance to high pH soils.
The last two growing seasons we have conducted trials in both western (McCook, North Platte) and eastern (North Bend) Nebraska to see what products in the Hoegemeyer line-up do well in these fields. The pH average for the plots has been 8.2 in 3 trials and 8.3 in another trial. All 4 trials have been done under irrigation. Certain products have shown some pretty impressive yield results. In the early season trial 7102 family has had excellent yield results. In the mid-season 7876 family products have been yielding well above the test average, and for the full season products 8294 family has done the same. If you’re interested in learning more about products that work on these challenging soils check out our Hoegemeyer High pH Study or contact your local Hoegemeyer DSM or Agronomist.

If you’re among the growing number of farmers facing increasing glyphosate resistance, you’re about to be faced with some difficult decisions. In fact, if resistant palmer amaranth, giant ragweed, kochia, waterhemp or marestail are among your list of concerns, planning now for the appropriate seed choice is imperative to maximum return on seed and herbicide investments.
For soybean growers, that means choosing a variety that allows you to use a different mode of action against those weeds showing signs of resistance to glyphosate. Hoegemeyer has a solid lineup of LibertyLink® seeds with varieties that range from a group of 2.3 to 4.9 maturities, so there is a seed for anybody’s acreage. These varieties also yield just as well, if not better, when compared to glyphosate-tolerant soybeans. Many customers who have taken advantage of the LibertyLink lineup have been very satisfied with its performance.
Choosing the right seed now will help your advance planning efforts for early season applications as well. Different from the glyphosate-tolerant soybeans, farmers should make sure to apply a pre-emergent herbicide when planting LibertyLink soybeans. For post-emergent herbicide applications, growers need to get the best spray coverage possible and hit weeds when they’re less than five inches tall.
If you have questions about Hoegemeyer’s LibertyLink soybean line-up or glyphosate-resistant weeds, contact your Hoegemeyer sales manager or agronomist. You can also get your 2016 Hoegemeyer Seed Guide here.
