Rain, rain, rain! A much needed rain this past weekend turned into a pretty substantial drenching for most of our area. Many of our farmers experienced everywhere from 2.5” to 6.5”. Fortunately, the rain came over the course of a day and a half and not all within a couple of hours. With the ground having been so dry before the weather event, a lot of the moisture got sucked up, but that still did not stop things from ponding up as the rain continued. As we look for the ponds to disappear over the next few days, some things we can keep an eye on include:

  • crop emergence
  • pre-emergence weed control
  • weed pressure
  • crop response to the freezing cold last week.
  • making sure your tile-inlets are all running.

We look forward to seeing some warmer weather over the next week, which will really help things take off now that we have adequate moisture.  As always, please contact your local agronomist for any questions you may have. We are always willing to come out and take a look at things with you. Thank you for your business and support.


Although we had exceptional planting conditions, we are still seeing a lot of variability in planting depth.

Be careful as you start to see plant response to wet soil conditions.  In these areas it is common to find off-color corn but it does not necessarily mean you have a Nitrogen shortage.

Since 1990, Minnesota has been 10% wetter on average … and spring and summer are becoming wetter at faster rates than fall and winter.  Pictured below is the Minnesota average annual precipitation.

High rainfall increases potential loss during the season through volatilization, denitrification and leaching.  One way to improve the efficiency of your Nitrogen fertilizer is to minimize the exposure to wet conditions by split application.

Nitrogen has one of the largest impacts on production costs AND yield.
Last year’s sidedress trials gave us an extra 10 ½ Bu / Acre.  Improving your Nitrogen efficiency by sidedressing can make a BIG difference in your bottom line.

What a difference a week makes.  Last week at this time we wondered when the rain and heat would come.  We welcomed a weekend soaking rain and the warmth is here. Currently in the Lewiston area, corn that was planted April 23rd has 170 GDU’s and corn planted May 1st is at 106 GDU’s.  Over the last week we seen an average of 7.7 GDU’s per day.

With the lack of moisture and heat we have had, our issues are currently with emergence in corn and soybeans.  Between the cold temperatures and seed sitting in dry topsoil we have seen very uneven emergence.  Corn fields that did not have a pre-emerge put down have seen the grasses, ragweed, and lambquarters starting to emerge very heavily.  Alfalfa that was nipped by frost over a week ago has rebounded nicely and is about 12-15 inches tall with some dairy producers looking at cutting first crop next week.


Corn on corn planted April 23rd.  All four plants were within 1/1000th of an acre. 
Stages ranging from just germinated to almost a V2 plant.   


Uneven emergence: Corn on soybean ground, planted April 23rd.  The plant on the left had cold imbibitional chilling injury and was leafing out underground.  All three plants were within three feet of each other.

Mother Nature provided some much needed rain for our area over the weekend with rainfall reports varying from 2.5 to 5 inches of rain. Not only did the crops need this drink of rain, but we needed it to activate all the pre-emerge herbicides that had been sprayed the last two weeks. I have seen fields that have had weeds push through the pre-emerge while waiting for the rain to activate the chemical. If its giant ragweed that has made it through don’t expect the chemical to “reach back” and take these weeds down; it’s time to come up with an alternative plan on these fields. The picture below is an example of this. Keep an eye on your fields notorious with giant ragweed.

Many of our no till or minimal till fields are experiencing slower emergence. I dug up these seeds yesterday and the twisted mesocotyls were headed in the right direction and should be emerging by the weekend. Just need some heat and patience with these acres.
