Soil Consulting and Crop Consulting in Illinois. You may call it soil testing, soil sampling, or soil health management, but it is more than that. These are my daily or weekly travels in soil and crop consulting and my observations in the agricultural world.

Continuous Corn Yield Penalty
I have written more than once about the continuous Corn yield penalty. No-Till Farmer offered this article on Understanding The Continuous Corn Yield Penalty . University of Illinois researchers peg the cause on N availability, corn stover accumulation, and unfavorable weather. This goes a little bit against conventional wisdom that the disease and insect cycles are a factor. However I find little argument with the conclusions. The researchers also found that the yield penalty continued to get worse each year of their seven year study. I wrote a blog in October on Corn Following Corn. It looks like I should add residue management to my suggestions on how to grow continuous corn. It looks like incorporation of residue to speed up decomposition would be advantageous.
