High grain prices for grain crops make any planting mistakes extremely costly. Most corn yield is determined within the first several weeks. Soybeans are a little more forgiving but any type of environmental (weather) or biological (weeds, disease, insects) stress can impact yields. Healthy plants tolerate stress better than plants that are nutrient deficient. For corn, the best time to plant traditionally has been May 1-through May 10th according to Ohio State University Research. Weather delays often make it hard to get all acres planted at this time. Current varieties have a tremendous ability to compensate and still get good yields, but getting that plant off to a good start is critical. Regarding soil health, soil microbes process the majority of the nutrients a plant absorbs. Cold or wet conditions slow microbial growth and hurt plant growth. Feeding the microbes may be more important than feeding the plant directly! On no-till corn with a cover crop, 50-75# of actual nitrogen (N...
