My dad has been no-till farming his corn forever (30 yrs). He does not own a corn planter. The local Soil and Water Conservation District rents the planter. Very reasonably. It's an insentive to do no-till, as farmers of my dad's category (22 acres tillable) could not afford to do it otherwise. The seed suppliers have developed some excellent cultivars (cultivated varieties, selectively engineered strains of crops for a specific trait) for no-till farming. One that has impressed me is round-up resistant soy beans. Unless you really sock it to 'em, they ignore round-up. Amazing.
One of the problems with no-till is much like the over use of antibiotics. Slowly the weeds are developing resistance to the spray chemicals. Mother nature and natural selection doing what it does, in the same way as the scientists did in the lab. She just works a little slower, but did show the way for the scientists.
