I don't think the farm bill is really about farming anymore.
I think it's all about unfairly and illogically subsidizing both the supply and demand side of farming.
Unfair, sure. There is nothing illogical about it, though.
It's illogical to subsidize no-till when someone can double crop with beans and mow it flat.
Isn't the no-till farming better for soil erosion and moisture retention?
It absolutely is but not when you end up mowing the beans flat anyway.
If you mow the beans flat, it is still better for soil erosion and moisture retention vs tilling the soil. Additional benefits are in weed (NOT THAT KIND OF WEED) control, but these benefits are not always shown in year one or two.
Here is fun fact: Weed seed can live in the soil for years without germinating and then, when the conditions are right, still be viable. At one small town KS football field, the small hill (bump, really) where the score board stood for years was bulldozed flat for the addition of a new scoreboard. After bulldozing, cocklebur seed that had been buried in the ground for over 30 years still germinated. KSU Weed scientist found that the germination rate of this cocklebur seed was nearly 80%
