Why is that? Certainly it is a major enough crop that herbicides have been developed for it. Maybe it is not where you are at but moisture conservation is one of the major benefits of not till. I would think that would be very important in most of Texas as well. Where I live now in Indiana it is typically not that important. I guess what really sold me on it was a field we had always fought with low spots that were wet when I was growing up. They never have that problem anymore. One time I went out there with my brother and we turned over a spade full here and there and everywhere was full of earthworms. He says that is the way it is all over - no tillage means you are not killing the earthworms which naturally aerate the soil. Another big factor is erosion control. One big issue they are concerned about now that we never used to is compaction. Of course equipment is larger but without tillage there is also no mechanical loosening of the soil so you have to give nature its time. Since they run a lot of beef cows and like cornstalks for pasture they have to be careful about when they let the cows in. A wet warm fall leaves the ground very vulnerable.
