Split your N!
This guy has some impressive yields.
Tramlines are the past. The future? Controlled traffic.
To grow great wheat requires a lot of trips across the field. You are going to stomp down a lot of wheat and compact a lot of soil if you drive at random. With tramlines, you drive in one place during that season. Put the tramline in the same place every year and you have controlled traffic farming.
What to do when spring comes and the wheat looks bad? Put N on it anyway. Another option is to over seed red clover, so it the wheat stays bad at least you get a crop.
