Take an offensive attitude in soil fertility
If this idea is correct, then it means that the issue is not that our land is poor, but that our practices are not supplying the crop at the time when nutrients are in greatest demand.
Other crops are also suppressed by this fertility management style, but cotton and soybeans don’t seem as sensitive. Ironically, growers with low corn yields probably spend almost as much on fertilizers and lime, but they are often working with a deficit rather than a surplus. You might say they are playing defense. Nobody ever won anything on defense alone, you have to play offense.
I expect skepticism about this “theory,” but for now it’s the only one I’ve got. For as long as I have been in this area I have heard farmers comment that our local soil “just won’t make corn.” But I am just stubborn enough to believe this may be a myth. Other factors including rainfall, drainage, tillage system, sunlight, planting date, variety, wildlife damage, etc., also play roles in the story.
We need to see our dryland corn consistently break the 150 bushel barrier unless rainfall holds us back. We should be able to do this in an era when the national corn yield record has been pushed to more than three times that amount.
