2 Fluid Journal Spring 2000 With only slight soil compaction, there would be approximately a 6-bu/A average corn yield increase by applying starters over 10 years. Where there was moderate compaction, the effect of the starter would almost double. Severe soil compaction, on the other hand, would cause more problems than the starter could overcome. Though there would be an 8-bu/A increase in yield that would pay for the starter, the grower would still be in financial trouble with only 138-bu/A corn at $2/ bu to cover $175 cash rent. The lesson here: the dealer can no longer just sell product. He must look at as much of the total production picture as is possible if he is to help the grower. Skill, not luck Skill, not luck Skll lc il,notuck Skill, not luck There simply is no substitute for local databases. Knowing more about crop production in your area than anyone else means survival for both you and your grower. It is difficult for growers to argue with a database that has their data asapartofit. Growers still look for crop production guidance. Dealers who weave together information about cultural practices that includes the right product for the right job will continue to be an invaluable asset to their growers.
