Dr. Fred Below shares his NREC-funded research that places emphasis on the preplant placement of nitrogen and compares nitrogen use by the corn with sidedress.
Two years ago I was walking a corn field that I had previously side-dressed with an ammonia bar. It was very dry and I could see purple corn roots that filled the open trench left by the applicator knife. The trench was in the middle of 30" rows. Are these roots that I had seen not used for feeding the plant?
Great insight by Prof. 260Ibs of nitrogen is actually recommended fertilizer nitrogen not overall nitrogen needed to grow 230 bushel throughout the season.
