Read some post in this forum about tilling and I think I basically understand why not, but it is hard to get used to. Raised on cotton and grain farm until I was in the 7th grade. Most boys on farms get started early working in the field. I was in the 4th or 5th grade when I started plowing. We plowed beds in preparation for planting, why I do not know. The first day I was turning the soil, it smelled so good. Got off the tractor and actually took a bite. Smelled wonderful, tasted horrible. Reckon this had an effect on my mentality? But to this day, fresh turned dirt still smells great.

There's a no-till cotton farm in the Panhandle. The guy sprays with molasses four times a season and has completely stopped irrigating. Due to the cost cutting of irrigation supplies, maintenance, labor, water costs, and no-till, he nets more than his neighbors in good years and in bad. His production may not keep up but his profits out perform.

What does he do for weed control?

Great question! I don't know.
I'll ask.
