The High Cost of Crop Production- Agronomics- Economics-Convenience
Do we need to change our priorities?

Weed control may never be easier than it is now.
Glyphosate- Inexpensive- Convenient
- Spray Corn. Move to soybeans and back to corn.
- Controls all weeds.
Glyphosate Needs Help- Difficult to control weeds - Dandelion
- Weeds that are potentially resistant to Glyphosate.
Important considerations
that need to receivemore attention
Objective-Uniformity. One plant should look
like another across the entire field.
Uniform Emergence- Firm soils at planting- Depth of planting- Soil to seed contact- Residue management- Tillage in same direction as planting- Be prepared to assist Emergence
Nitrogen:Normal Minus 50
Greater yield differences were observed when nitrogen was applied as UAN compared with trials where it was applied as anhydrous ammonia.
The higher nitrogen rate was usually profitable when yields were higher than 200 bu/acre.
Nitrogen: Fall N vs. Spring N
Nitrogen:Spring NH vs. Spring UAN
Nitrogen:Manure Plus 50
