Hydroponic Approaches and Value to the Food Supply Chain
STACY ADAMS
Professor of Practice, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Alternative production practices must be employed to supplement and secure the future of the global food system. Hydroponics may address challenges associated with distribution interruptions, environmental influences, socioeconomics, catastrophe, and war. Opportunities exist for entrepreneurship or farm diversification into high value specialty crops. This presentation highlights hydroponic approaches and value within the food supply chain.

I Want TO...Science + Art Process to Create Landscapes for Plants and People
KIM TODD
Professor and Extension Horticulture Specialist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
The positive effects of exposure to nature are well-documented, yet decisions are often made based on lack of understanding about all landscapes as systems. This seminar will demonstrate a simple universal process that can result in creation of beautiful, practical, manageable, and resilient landscapes of any size that enhance human well-being.

Toward Adaptive Grazing: Leveraging Different Rangeland Monitoring And Assessing Techniques
BIQUAN ZHAO
Postdoctoral Research Associate, Department of Animal Science, University of Nebraska–Lincoln
Adaptive Grazing has been aware of a strategy for rangeland management. Implementing adaptive grazing is challenging due to the dynamics in forage production, livestock behaviors, and external environment such as climate change. This talk covers my research in long-term forage production monitoring for plant functional groups, forage biomass estimation by using drone remote sensing, and cattle grazing behavior modeling through GPS collars. Those rangeland monitoring techniques were utilized to enhance our understanding of rangeland dynamics and can help better application of adaptive grazing strategies.

Advancing Digital Agriculture for Improving Agronomic Decisions
IGNACIO CIAMPITTI
Professor, Farming Systems, Department of Agronomy, and Director, Institute for Digital Agriculture and Advanced Analytics, Kansas State University
This presentation will focus on discussing the bottlenecks for translating science into actionable management and topics related to digital agriculture, and use of new technologies such as satellite imagery and new data visualization to assist producers on developing relevant agronomic decisions.

Nitrogen and Water Management Strategies to Reduce Nitrate Leaching in Irrigated Sandy Soils
ARSHDEEP SINGH
Doctoral Candidate, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Nitrogen and water are essential inputs for getting a high corn yield. However, excessive nitrogen and water inputs can deteriorate environmental quality. Optimizing these inputs can result in profitable corn production with less environmental impact. This presentation will focus on in-field strategies for optimizing nitrogen and water inputs to improve nitrogen use efficiency and decrease nitrate leaching losses in irrigated corn fields of Nebraska.

Rapid Soil Sensing for Precision Agriculture and Carbon Market
YUFENG GE
Professor, Department of Biological Systems Engineering, University of Nebraska–Lincoln
Dense, quantitative soil data are increasingly demanded for applications like precision agriculture, climate modeling and carbon crediting. Ge's lab has been working on enabling tools and systems for rapid, low-cost measurement of soil properties. In this seminar, Ge will cover a few projects his team have worked on, key results and lessons learned.

Impact of Land Use on the Storage and Turnover of Soil Organic Carbon: Stories from the Subsoil
Michael Kaiser
Assistant Professor of Applied Soil Chemistry, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Land use change is one of the main drivers of organic carbon storage in soils but significant knowledge gaps exist towards the response of biogeochemical cycles in the subsoil. In this seminar, Kaiser will present and discuss data from more than 20 sites in Nebraska. At these sites they sampled soil under cropland, native prairie or forest down to depths of at least 3 meters. The samples were analyzed for carbon storage and turnover, ecologically relevant carbon fractions, microbial community structure and soil mineral characteristics. The data of these analyses can help to develop improved land use strategies to increase the long-term carbon storage beyond the topsoil.

Integrating Agronomy and Machine Learning to Analyze Yield Gap Magnitudes and Causes from Field to Global Levels
FERNANDO ARAMBURU MERLOS
Research Assistant Professor, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Identifying untapped opportunities for crop production increase is crucial to guide food security interventions. In this presentation, Merlos will show how agronomic knowledge, big data and machine learning can be integrated to map yield potentials at high resolution and identify agronomic practices that promptly deliver large on-farm yield gains.

This seminar has been CANCELED:
The FoodU Program at Auburn University
DESMOND LAYNE
Head and Professor, Department of Horticulture, Auburn University
FoodU provides Auburn students with transformational food system learning experiences as they grow hyperlocal fruits, vegetables, herbs and flowers to support consumption and utilization in Campus Dining, the Culinary Sciences program and in two on-campus restaurants. Produce is grown outdoors in raised beds, in greenhouses, vertical farms and on a rooftop. Program highlights, best practices and challenges will be discussed.

Advances in Quantitative Trait Modeling
TIANJING ZHAO
Assistant Professor of Theoretical Quantitative Genetics, Department of Animal Science, University of Nebraska–Lincoln
BRIAN RICE
Assistant Professor of Quantitative Genetics, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
INDRANIL MUKHOPADHYAY
Professor, Department of Statistics, University of Nebraska–Lincoln
Quantitative genetics is crucial for understanding complex traits, enhancing crop and livestock breeding, and tackling challenges such as food security and environmental sustainability. However, the breadth of topics in quantitative trait modeling is vast. In this seminar, three experts will discuss how cutting-edge research, mentoring students, and securing funding for innovative projects, can contribute to addressing global food security. Co-sponsored with the Department of Animal Science and the Department of Statistics.
