Early in spring, pre-emerge herbicide was applied to our corn fields. This picture shows how necessary that is. These 12 rows are in a location that we cannot get to with our field sprayer and no herbicide was applied early. You can see the weed pressure that exists in this part of the field. Those weeds will quickly rob the corn of it’s full yield potential.
Post emerge spraying will clean up weeds that come through the early application. Later we will cultivate these fields and build ridges in the corn that will serve as the seedbed for next year’s soybeans.
As planting nears, we need to be assured that our liquid handling systems are working well. It’s a tricky call as to when we can put water in these systems and not risk having them frozen and cracking components. Once testing is done the equipment is stored in a closed machine shed during freezing nights yet to come.
April 1 and 2 were the days we felt comfortable with this call. The planter handles liquid fertilizer, specifically Ammonium Thio Sulfate (ATS), that is banded as a narrow stream over the seed once the furrow is closed. The rain will then take the nitrogen (N) and sulfur (S) down to the roots. We apply 8.3 gallons/acre to get a total of 24 #/Acre of S on the field. The N is just an added bonus to the S application and is subtracted from the total N we put on our fields so we don’t over apply our nitrogen. The fertilizer application is controlled by our John Deere GS3 monitor mounted in the cab. We also have a controller for insecticide application using the Smart Box system as well as a Precision Planting 20/20 monitor system tied to an iPad for precise monitoring of seed placement.
Our Top Air sprayer handles the bulk of our chemical applications for weed control. It needs to be in top notch condition for application of herbicides soon after planting. The soybean pre-emerge herbicide has a 3 day window to be applied so it won’t damage emerging seedlings.
After a long, cold spring the weather has finally turned favorable for corn planting in Redwood County, MN. There were a few neighbors putting in corn last week but planting began in full force on Monday, May 6 from most area farmers. Everyone worked hard and fast with the impending rain in the forecast for Wednesday. The rain did come and now we wait again for the next window of opportunity.
There were some great presentations and two-way dialogue between university researchers and attendees at the 2013 Soybean Symposium sponsored by the U of M and the MN Soybean Research & Promotion Council. This event has been held at the U of M Landscape Arboretum since it’s inception.
This year’s sessions focused on resistance management of soybean insects, diseases and weeds as well as corn root worm beetles. Attendees were crop consultants, farmers, agronomists as well as a number of ag media representatives. The seed company reps may have been uncomfortable with some of the topics discussed because, if the farmers followed the recommendations, especially on soybean seed treatments, it would go against what they’re pushing on the farmers.
