One of the challenges that farmers face is deciding which nutrient sources to use and how much to apply to their fields. The online tool predicts corn yield based on the amount of nitrogen that is slowly released from the soil and decomposing cover crops. Using site-specific information, the tool calculates the amount of nitrogen needed to supplement the existing soil fertility and to achieve a goal for corn yield.
