Agriculture in 2030: Chuck Rice perspective

University Distinguished Professor, Mary L. Vanier University Professorship, Agronomy, Kansas State University

Agriculture is set for a transformational change. Breakthroughs in sensors, root dynamics and the plant-soil microbiome will increase efficiency and resiliency. Cropping system designs will include efficiency and resiliency goals for the field and the landscape. Data and artificial intelligence will increase support for decision-making. The big question is who will fund these advancements and are land-grant universities set to lead?

PPO herbicide resistance in weedy Amaranth species

Field Market Development, Valent USA

PPO herbicide resistance in weedy Amaranth species is a less publicized, yet important topic in soybean weed control. PPO herbicides are a foundational mode of action for residual weed control in soybeans, and widely used in postemergence tank mixtures. This presentation provides an update on the status of PPO resistance in the Midwest and research on resistant Amaranth populations.

Automation and Robotics in Agriculture

Assistant Professor, Advanced Machinery Systems, Biological Systems Engineering, IANR College of Engineering, University of Nebraska–Lincoln

This presentation will discuss the evolution of agricultural machinery from simple mechanical machines to autonomous driverless robotic machines and advances in automated machine performance data collection. Pitla will also talk about trends in field automation and the aspects of equipment size as related to field productivity, field efficiency, and technical obsolescence.

Hopping to it: The Growth and Viability of the Nebraska Hop Industry

Hop Program Coordinator, Nebraska Extension

The hop industry in Nebraska has experienced much growth in recent years. Kreuser will discuss the factors that enable the plant to thrive, the challenges faced in hop production and the exciting possibilities the industry has ahead.

Cover Crops in Nebraska – Expectations and Realizations

Postdoctoral Research Associate, Agronomy and Horticulture, University of Nebraska–Lincoln

Cover crops have the potential to improve soil health and provide grazing for Nebraska farmers looing to reduce erosion and soil nitrate loss. However, the predominant corn-soybean rotation limits the selection and productivity of cover crops. Koehler-Cole will present findings from four years of research in no-till corn and soybean systems in Nebraska with implications for both cover crop and main crop management.

Leveraging Genomics, Genetics and Breeding to Understand Crop Adaption to Nutrient Stress

Research Geneticist, Corn Insect and Crop Genetics Research Unit, USDA-ARS, Iowa State University

Plants require 20 micronutrients for proper growth and development, but environmental conditions often limit soil nutrient availability resulting in stunted growth and reduced yield. O'Rourke will discuss how she combines functional genomics, physiology and plant breeding to identify biological pathways and gene networks associated with nutrient deficiency responses and enhanced stress tolerance.

Nitrogen Fertigation in Corn

Assistant Extension Educator, Agronomy and Horticulture, University of Nebraska–Lincoln

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.
