slide3

Seven Wonders of the Corn Yield World

  • Ranks those factors that each year can have a positive (and sometimes negative) impact on corn yield
  • Gives each factor an average bushel per acre value
slide4

Crucial Prerequisites, but Not Yield Wonders

  • Drainage
  • Pest/Weed Control
  • Proper soil pH & adequate levels of P and K based on soil tests

How to Get 300 Bushels?

  • Provide better prerequisites, especially mineral nutrients
  • Try to optimize each of the seven wonders and their positive interactions
slide8

Prerequisites for 300 Bushels?

  • Proper soil pH & adequate levels of P and K based on soil tests
  • Fertility- Required amounts of nutrients each year, Sulfur & Micronutrients?

How to Get 300 Bushels?

  • Better prerequisites along with packages of optimized yield wonders.
  • Is the value of combined factors greater than their individual impact?

conclusions
Conclusions
  • Big yield gains are possible from crop management that provides better Fertility along with packages of optimized Yield Wonders
  • The yield value of an individual factor is small compared to the combined value of all factors
