Nitrogen Fertigation in Corn
The elevated levels of nitrate in groundwater in Nebraska are considered a direct result of Nitrogen management in corn production. Decades of research have attempted to develop methods that increase the use efficiency of applied N, while also optimizing profit for growers. A new approach to N management will be discussed that utilizes a combination of crop canopy sensors with and without the use of a crop model to aid in decision making. Results are promising.
