Green Snap in Corn

Jun 22, 2017 by Travis Dollarhide
This is the time of year when much of the Corn Belt enters one of the most susceptible periods for wind damage to occur. In particular, strong winds during periods of rapid growth can cause green snap in corn. While this type of stalk breakage can occur anywhere in the Corn Belt it is much more common in the fertile, wide open plains of the...

“Floppy” Corn Syndrome

Jun 15, 2017 by Steve Crafton
I have been getting some calls from farmers in west central and east central Illinois about corn that is “falling over.”  I went out to inspect these concerns and just like in 2012 I found corn “falling over “with no roots; or in other words - “Floppy” or “Rootless” corn syndrome.  We...

Relative Meal Value of Soybeans – a new concept

Jun 9, 2017 by Mark Seem
Determining a relative meal value score to differentiate soybean varieties based on their soybean meal value for swine has been introduced by the High Yield PLUS Quality (HY+Q) project that is funded by the Illinois Soybean Check-Off. LG Seeds submitted 223 soybean samples to the HY+Q project in 2016. These were part of a larger sampling and grain...

Nitrogen Loss Due to Saturated Soils and Excessive Rainfall

Jun 9, 2017 by Corey Prosser
A question a lot of farmers have been asking, besides should I replant, is how much nitrogen has been lost due to all the rain? This question is not an easy one to answer due to the fact that there are many factors that impact the amount of nitrogen that could be lost. The type of nitrogen: whether it be Anhydrous Ammonia, Urea, or UAN 28-0-0 or...

Western Region - California

Jun 5, 2017 by Phil Miller
Grain corn planting in the Delta region is quickly coming to an end.  Single crop silage is pre tassel and looking very good in the Central Valley.  We are in the middle of planting double crop silage corn behind winter forage.  Weather has been very favorable for corn production with the exception of a few over 100 degree days in...

Southern Illinois and NE Missouri Crop Progress

Jun 4, 2017 by Brian Weihmeir
Southern Illinois: Across southern Illinois, growers have had a tough start to the growing season. With cool and wet weather in April and May, many growers struggled to get the corn crop in the ground. Farmers were also faced with tough replant decisions in their fields due to the unfavorable weather. A good amount of the corn...

Northern Illinois Crop Progress

Jun 4, 2017 by Steve Crafton
The planting season in Northern Illinois is finally coming to an end for most farmers.  We still have a few acres north of I-80 to finish planting and some replant in our central region to go, but 98% of acres have at least been planted once.  Weather looks like it’s going to cooperate this week so most everyone should finish up...

Western Iowa and Northwest Missouri Crop Progress

Jun 4, 2017 by Greg Peters
It seems that every year since 2009 has many producers saying “I can’t wait for a normal year”.  2017 has been no exception to this.  The winter was one of the warmest on record and it looked like spring planting was going to go hard and fast.  Soil temperatures warmed into the 50’s and 60’s in the...

Plains West Crop Progress

Jun 4, 2017 by Matt Teply
Southwest Missouri:   This area of the region is working towards wrapping up all the corn acres.  There was a tremendous amount of replant in this area in 2017 because of extremely wet weather.  The last 10 to 14 days has allowed things to dry up enough that most...

Eastern Iowa Crop Progress

Jun 4, 2017 by Ryan Dunsbergen
The crop planting report released by the USDA on May 30th showed that Iowa corn was 97% planted with 82% emerged.  It also showed that Iowa soybeans were 77% planted with 39% emerged.  The weather we had last week was very conducive to farmers making the final push towards getting #plant17 wrapped up and in the books.   May was a...

Plains East Crop Progress

Jun 3, 2017 by Leonard Luebker
The Plains East Region consists of Northeast Kansas, Eastern Nebraska, (Northeast, East Central, and Southeast), and Southeast SD.  The region has changed considerably the past couple of weeks.  Southeast Nebraska is probably the only area in this geography that was able to plant corn and soybeans in a timely manner.  ...

Ohio Crop Progress

Jun 3, 2017 by Corey Prosser
To say the least, this spring has been very challenging for everyone across the state. There were many areas that were able to plant early and many areas that have yet to plant. With the amount of rainfall many areas have had replants of both corn and soybeans which has been a struggle with wet conditions. Central and Western Ohio are finished...

Minnesota and Wisconsin Crop Progress

Jun 3, 2017 by Logan Vaughn
As we enter the month of June, growers in Minnesota and Wisconsin are continuing to make progress on completion of corn and soybeans planting as fields become fit. The spring weather pattern has not only made it very challenging to complete field activities but also difficult for planted fields to get off to a fast start. April planted corn...

Indiana and Mid-South Crop Progress

Jun 3, 2017 by Jesse Grogan
Weather conditions are a challenge this spring which is normal in the eastern and southern Corn Belt. Heavy rains in late April with cool temperatures delayed crop growth, caused flooding and soil crusting which led to replanting many acres established in the period of April 24 to April 28. May conditions were a series of several dry days or hours...

Corn and Soybean Replant Decisions

May 24, 2017 by Brian Weihmeir
This year has been a tough one for areas of the Midwest. Cool and wet weather since planting has left fields with lower than desirable stands and ponded areas. With some areas sitting idle due to Mother Nature, growers have had the time to look at their fields and evaluate their stands. Depending on their planting rate and other factors, some...

Vomitoxin

May 22, 2017 by Greg Peters
Ear molds were a common problem in 2016 because of high rainfall that occurred as ears of corn were developing.  Usually these molds don’t cause too much of a problem because the infected kernels blow over the shoe of the combine if fan speeds are increased.  It is also recommended that grain that is going to be stored from fields...

Temporary Early Season Nutrient Deficiencies in Corn

May 11, 2017 by Leonard Luebker
How can there be an early season nutrient deficiency, if the soil test shows everything is good?  Early season nutrient deficiencies, may occur in corn, whether one sees the deficiency or not.  Nutrient usage by corn plants, requires a healthy, growing root system.  ? Emerging corn: This corn was...

Early Frost Damage in Corn

May 9, 2017 by Matt Teply
Having lived in SW Nebraska most of my life, I have unfortunately been in more than my fair share of corn fields that have had a frost or a freeze after corn has emerged.  Freeze damage in corn is often hard to evaluate the day after it happens.  Especially in a crop that is maybe just at the V1 to V4 leaf stage. Most of the time there...

Purple Leaves in Corn

May 4, 2017 by Steve Crafton
A fair amount of corn has been planted across the Corn Belt the past few weeks.  Spring rains have been ample across the Corn Belt and temperatures are expected to drop into the lower 40’s again this week. It would not surprise me to hear reports of farmers seeing reddish-purple leaves in their young corn plants. Cool conditions, soil...

Ponding Effects on Early Stage Corn

Apr 28, 2017 by Matt Teply
With the recent weather and the 14 day forecast of continued wet and cooler weather there are going to be areas of ponding or standing water in corn fields.  Being from Western Nebraska we see ponding in corn fields but it is normally man made, irrigation, and expected.  But, every now and then we get a toad drownder of a rain and we...
