"Big Yield Increases in Corn and Beans Coming" by Tom McGraw
"...Before we get too excited, I’ve got a couple of old bromides you might want to consider. “More horses take more hay.” More bushels will require more inputs. X number of bushels of anything takes X number of pounds of P and K. Twice the number of bushels takes twice the number of pounds of P and K. “There is no free lunch.” With increased potential in the seed, there has to be a corresponding increase in agronomy management to realize that potential. Water management (variable rate irrigation, drainage, subsurface irrigation, water table control, better water retention though managing and/or alleviating compaction) will need to be improved. There are huge chunks of the Corn Belt that are very inadequately drained. Farmers should take the windfall commodity prices and invest some significant dollars in increasing the productivity of the land through drainage. They ought to do that no matter the price of corn. Fertilization, tillage, everything needs to rise with the rise in seed technology. Precision ag looks all the more enticing the higher the stakes...."
