Mineral Nutrition for High Yield No-Till Corn

Fred Below talked about high yield corn and how to get it.  He had several pertinent comments about micronutrients. He pointed that most micronutrients are mobile in the plant and go where they are needed.  He says boron is needed for silk growth and pollination. Below says that corn needs zinc to fill grain. Sulfur is needed for grain too. He likes micro essentials  sz placed 4 to 6 inches deep.  It contains nitrogen, phosphate, sulfur and zinc.  His research is showing a response even when soil has up to 45 ppm of P. He says that no plants are left behind with his treatment.  He admits that he is nature what element causes the response.  It could be only one thing in the mix.  It was interesting that Below also said that cover crops play a big role in keeping nutrients available.
