Seems that our AgVenture message about proper corn planting depth would be simple enough yet achieving that correct depth in the field is still elusive for many, and I believe those who are too shallow are in for big trouble this growing season. Already the damage is showing with results like in the first picture... plants with no firm anchor to the soil. In the second picture, you can see how much shallower the "falling over" individuals were planted than nearby cousins placed at a better depth.
My take home from today's observations are:
1. If you planted at 2 - 2.25 inches deep in loose fluffy soils, after a rain your seed was no longer 2 inches deep.
2. Setting your planter for 2 - 2.25 on firm soils doesn't mean your actual was that deep.
3. Shallow plantings will be trouble all through the season, with trouble evident A) now B) prior to tassel with wind events that may occur and C) late season root lodging, just to name a few key periods.
We have been taught by the best > what happens the day of planting sets the tone for everything thereafter.
