In Platte County, Brent Melliger, Luan Oliveira, and Bruno Lena are conducting two studies on nitrogen management in corn production. One study evaluates different sidedress nitrogen ramps in a furrow irrigated corn system while the other study looks into the impact of biological products under different sidedress nitrogen ramps in a center pivot irrigated corn system.
The goal of this study is to identify which nitrogen rate results in larger marginal net return. Information on rainfall and irrigation amounts is also being collected during this study with the intention of using the data to improve nitrogen use efficiency. This data, along with data from other on-farm research studies, will be used to help Nebraska farmers improve their crop yield and production practices in the future.
