On-farm Testing of Biological Nitrogen Technologies
With rising nitrogen (N) fertilizer prices, environmental concerns and pressures related to N fertilizer use, many farmers are looking to alternative products and sources for supplying N to corn. Among these technologies are biological products, such as Pivot Bio PROVEN® which utilizes a N-fixing bacterial inoculant for cereal crops. Others, such as SOURCE®, use a biochemical stimulation of the soil native microbiome to support plant growth. These technologies aim to improve nutrient use efficiency by reducing a portion of the crop’s N synthetic fertilizer requirement. There are remaining questions about how these technologies perform on farmers’ fields and under various N rates and soil types. Results from 2021 and 2022 on-farm research experiments testing these technologies on yield, profit and nitrogen use efficiency will be presented.

Laila Puntel
Laila Puntel is an Assistant Professor in Soil Fertility and Precision Ag. She has a research, extension and teaching appointment since 2019. Originally from Buenos Aires province, Argentina, Puntel grew up in a productive corn, soybean, wheat and barley region. She obtained a Bachelor of Science in agriculture engineering from the National University of Mar del Plata, Buenos Aires, Argentina, and a Master of Science degree and doctoral degree in crop production and physiology from Iowa State University. Before joining UNL, Puntel co-founded and worked in a Precision Ag and Soil Testing Lab consulting business for six years (Clarion, Nueve de Julio, Bs As, Argentina) and worked for almost a year at an Ag Tech Company (CiBo Technologies, Cambridge, MA) as a Crop Scientist and Modeler. Dr. Puntel research and extension at UNL primarily focused on nitrogen management in cereal crops and the use of innovative technology to improve nitrogen use efficiency.
