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

Current Prices- November 23, 2007 (From one source) Anhydrous Ammonia – $600.00/ton $0.366/lb N 0-0-60 - $307.00/ton $0.256/lb K2O 18-46-0 - $507.00/ton $0.40/lb P2O5 10-34-0 Liquid Starter – $2.15/gallon Urea and Nitrogen Solutions projected to be about $ 0.52/ lb Nitrogen

Weed control may never be easier than it is now.
8
Glyphosate - Inexpensive - Convenient - Spray Corn. Move to soybeans and back to corn. - Controls all weeds.
9
Glyphosate Needs Help - Difficult to control weeds - Dandelion - Weeds that are potentially resistant to Glyphosate.
10
Important considerations that need to receive more attention
11
Objective- Uniformity. One plant should look like another across the entire field.
12
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
14
Nitrogen: Normal Minus 50
16
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.
18
Nitrogen: Fall N vs. Spring N
20
Nitrogen: Spring NH vs. Spring UAN
22
Nitrogen: Manure Plus 50
