I first knew Mike McNeil at Iowa State as we were both initiated into Alpha Zeta, and agricultural honorary.

I agree with most of what Mike says except one thing: ORGANIC if it is done the way most of those farms in his area are doing it as I have observed. Those farmers are tilling10-12 times per year and that is not good for the soil. Tillage destroys organic matter, the most important part of soil biology. Organic Matter in the prairie before farming began was 8-10 %. Many farms now have 2-3% OM. Using cover crops and no till allows us to increase the OM and biology of the soil. We have a farm in that area that had OM levels of 3.7 % when we started with cover crops and no tillage in 2016. We have now raised them to 4,2%. We have also been able to reduce the amount of synthetic fertilizers we use and cover crops are great in weed suppression so we are using less herbicides, no insecticides and fungicides on our crops. The way those farmers are tilling their soil requires a lot more energy than no tilling with cover crops.

A bit of optimism that maybe farm country WILL change?
