Unmanned aerial systems (UAS) in agriculture: State of the art
Assistant Professor, Crop Production & Cropping Systems Specialist, Department of Agronomy, Kansas State University

Global food security must address the dual challenges of closing yield gaps while improving environmental sustainability. The use of new technologies, such as uses of unmanned aerial systems (UAS), can play a critical role in addressing challenges.  Kansas State University  research on the diverse uses of UAS  for agricultural applications will be discussed.

Social media: A revolution in modern agricultural communication
Assistant Professor, Crop Production & Cropping Systems Specialist, Department of Agronomy, Kansas State University

Ciampitti will talk about the use of social media by Department of Agronomy and Cropping Systems group at K-State University  to provide unbiased and science-based Ag information. The information shared via social media quickly reaches the target audience, providing timely educational and outreach contents. The most successful examples have been infographics, timely pictures of production issues, presentations and papers uploaded, and information on the use of new technologies.

Buffalograss—native with unique challenges
– Assistant Professor, Turfgrass Genetics, UNL Agronomy and Horticulture

Buffalograss, like many specialty crops, has limited publicly available genomic data, complicating genetic-based breeding strategies.  Amundsen will discuss how modern RNA sequencing applications are advancing buffalograss cultivar development.  He will also dispel myths of buffalograss management and discuss advancements in the understanding of seed and winter dormancy mechanisms.

Corn residue grazing and baling effects on soil physical properties
Associate Professor, Agronomy and Nutrient Management Specialist, UNL Agronomy and Horticulture,  West Central Research and Extension Center

Corn residue grazing and baling can provide a valuable and cost effective means of feeding cattle and is a common practice Nebraska.  However, there are concerns about the effects of residue removal on corn yields and soil physical properties. The results of a long term study concerning this issue will be presented.

Leveraging the power of farmer data to empower agricultural research
Assistant Professor, Water for Food Institute Fellow, UNL Agronomy and Horticulture

Increased regulatory pressures on the environmental influence of agriculture and requirements for farm reporting on factors affecting environmental impact will likely increase. Grassini will show how on-farm data provide an unprecedented opportunity to benchmark the impact of management practices on yield and efficiencies of water and fertilizer applications and to orient high-cost, multi-year, multi-site field studies.

Nebraska On-Farm Research Network: Using data to drive decisions
LAURA THOMPSON Assistant Extension Educator, Southeast Research and Extension Center

Nebraska Extension has been working with farmers to conduct on-farm research for over 26 years.  Farmers participating in the on-farm research network take an active role in the research, addressing questions that impact productivity, profitability, and long-term sustainability.  Thompson will discuss the recent growth of this program, tools the network has developed, results from 2015 research studies, and future directions for the network.

Ecosystem services and environmental consequences of lawns and turfgrass management
Associate Professor and Extension Specialist, Department of Soil Science, University of Wisconsin-Madison

Turfgrass is the predominant ground cover in urban land uses, covering approximately one-third of developed land in the US. Therefore it is important to understand the environmental consequences and the urban ecosystem services provided. This seminar will summarize the state of the science of turfgrass in the urban environment with respect to ecosystem services, soil quality and management  and socioeconomic concerns of turfgrass management.

Freezing damage requires membrane remodeling and photosynthesis requires thylakoid dynamics
Assistant Professor, UNL Biochemistry

Out-of-season cold snaps are increasing with changes in weather patterns, and resultant crop and landscape damage can have large economic impacts. Roston will review mechanisms to withstand cold and freezing in plants and recent data on a critical post-translational signals, which control membrane responses to freezing. She will also discuss the relevance of thylakoidal membrane dynamics to efficient plant growth and development.

Improving soybean yield under drought
Professor, Soybean Breeding and Genetics, UNL Department of Agronomy and Horticulture

In Nebraska, water is the main limiting factor in soybean yield. Soybean yield response to water is linear, and soybean genotypes differ in their water use efficiency as measured by yield per unit water applied. I will discuss options to improve soybean yield response to water and implications for both irrigated and rainfed production systems.
