2018 Test Plot Summary

Hiawatha Implement in cooperation with Taylor Farms, Jacobson Farms, and Morris Farms conducted three corn trials and one soybean trial in 2018. On Taylor Farms we compared NH3 placement and seed placement on corn and on soybeans we tested late season application of dry nitrogen. On Jacobson Farms we tested different NH3 application row widths with different row widths on corn. On Morris Farms we tested post application of dry nitrogen on corn. We would like to thank these three growers for their cooperation in these trials. It wouldn’t have happened without them.

Dicamba Soybeans

Dicamba tolerant beans is a hot topic right now in most coffee shops and retail chemical outlets. Weed control is a critical component of yield potential. Dicamba tolerant beans is another way to control resistant waterhemp in your fields. Dicamba is a chemical that has been around since 1958, and has had quite a bit of use and criticism. In the late 80’s Marksman was a go to product for post emerge use in corn. This product was a pre-mix of banvel and atrazine. Banvel, the original dicamba product, was very volatile and drift was always an issue. It seems to me, who sold a lot of acres of Marksman, that the drift of Banvel was a minor thing. Very very seldom did drift from Banvel do more than cup the leaves of soybeans, and the next emerged trifoliate would seldom show the effects of Banvel. Fast forward to today and the potential of drift is the major topic of dicamba tolerant beans. Below is a photo of dicamba drift on non-dicamba tolerant soybeans.

Spring Nitrogen

A wet fall and winter does not necessarily mean this spring will be any different than normal. Bryce Anderson, a meteorologist with DTN, has stated that some forecast models are indicating a prolonged winter and a late spring. At the same time, five days before the Chiefs were playing the Patriots, the forecast was for single degrees. Game day morning the forecast was for a high of 27 degrees. This last example shows you the uncertainty of weather forecasting.

Drones in Agriculture

On February 4, 2002, reputably, the CIA used an unmanned aerial vehicle (UAV) in a targeted killing. The intended target was an individual whom the CIA thought was Osama Bin Laden. Fast forward to 2018 and UAV’s (Drones) are still being tested for targeted killing. Only now the targets are pests in agriculture, i.e.…weeds and diseases. Drones are being set up with the capability to find and spray a herbicide on weeds or a fungicide on an area that is showing disease.

Field Damaged Soybeans

This year many of NE Kansas and NW Missouri soybean fields were affected by drought. Although the severity varies significantly in our whole area, and in several cases, from field to field, the vast majority of your fields were affected in some way. The most troublesome effect from drought is yield loss, but, there are several other effects that we are seeing now that we are harvesting soybeans. Although this past summer was very dry, this fall has been very wet in areas. This wet weather has caused some challenges with this year’s soybean crop in ways other than delays in harvesting.

Flooded Acres

The Flood of 2019 started with heavy rains in the fall of 2018 in the area that drains into the Missouri River, above and below the dams. This was followed up by a colder than normal winter, and above normal snowfall. In early March 2019, the National Operational Hydrologic Remote Sensing Center, estimated 2-4 inches of water in the snow that covered a large portion of the frozen ground that drains into the Missouri River below Gavins Point Dam. Across this same area there was warming temperatures and heavy rainfall. The frozen ground made the melting snow and rain run off the fields and into the streams and tributaries that flow into the Missouri River, which were already higher than normal from the rainfall last fall. This caused major flooding upstream on most of these rivers.
