After what seems like the longest winter ever, it looks like spring is finally here. Our planting window is somewhat compressed, but 100% of yield potential can be expected for at least another three weeks on corn and five weeks for soybeans for most of the region. Conditions and progress vary, as expected, across NuTech’s Central Region.
Joe Kinscherff, our DSM from Pike County, IL, shared these photos with me last Saturday or corn and beans planted on April 5th.
In the northwest part of our region near Blooming Prairie, MN, NuTech dealer Brian Trius with Newry Ag, says they’re about 10 days out but the snow has melted and forecasted warm weather and rains will help get the frost out.
There’s been some talk of switching hybrids and I’m reluctant to even bring it up but I’d like to nip this talk in the bud as we are not even close to the “switch hybrid” date. Click here to read the article from University of Wisconsin.
Soil temperatures are rising quickly so it’s pretty much go time when soil conditions are fit. Table 1 in this article from Iowa State is a good guide for determining soil moisture:
|Soil Moisture Remaining (Field Capacity)||Moderately Coarse Texture||Medium Texture||Fine and Very Fine Texture|
|100%||Upon squeezing, no free water appears on soil, but outline of ball is left on hand.||Forms a ball, very pliable, slicks readily.||Easily ribbons out between thumb and forefinger.|
|100-75%||Forms a weak ball, breaks easily when bounced on hand.|
|75-50%||Will form a ball, but falls apart when bounced in hand.||Forms a ball, slicks under pressure.||Forms a ball, will ribbon out between thumb and forefinger.|
|50-25%||Appears dry, will not form ball with pressure.||Crumbles, holds together with pressure.||Somewhat pliable, will ball under pressure.|
|25-0%||Dry, loose, flows through fingers.||Powdery, crumbles easily.||Hard, difficult to break into powder.|
A few other things to watch:
- Iowa State reported seedcorn maggot in corn in southern Iowa earlier this week
- Black cutworm flights have started (I caught my first moth this morning in an Iowa State sticky trap)
Iowa State is working with cooperators across the state to run pheromone traps for true armyworm and black cutworm moths. These moths fly up from the south each spring and by monitoring the flights we can estimate when the larvae will emerge and begin feeding. Iowa State will release predicted cutting dates in early May.
