And anhydrous ammonia is good for you. Half of the people that use it farm the other half make crystal meth out of it. But when you plant corn then soybeans, corn then soybeans year after year what do you expect to attract? Naturally in large quantities of the same crop over and over pests are going to show up and you are going to have a problem. It's pretty logical to me. I would think the large concentration of the same crop is more attractant to pests than poor soil. At the same time you are killing the beneficial insects along with the pests. I would think the more sensible approach would be to balance the system and not be so greedy as to try to squeeze that extra bushell out of an acre.
