Unmanned aerial systems (drones) in agriculture

DON ADAMS – Professor, District Director,Animal Science Department, West Central Research and Extension Center, University of Nebraska–Lincoln

This mini-symposium featured four talks from UNL faculty and two talks from external speakers from the UAS industry. The talks covered a wide range of material from technical aspects of UAS usage to data analysis and applications in agriculture. The symposium ended with a brief panel discussion.

Drones are quickly becoming more and more commonplace as individuals and businesses find new ways to use them. Significantly cheaper than the traditional manned airplane or helicopter approaches to obtaining aerial imagery and sensor data, increased drone use is transforming the work of those involved in the agriculture industry.

University of Nebraska-Lincoln faculty and drone industry experts will discuss the use of unmanned aerial systems from the technical aspects of operation and data collection and analysis, to application in agriculture and legal use.

Domestic rubber production – Stretching over the value chain

KATRINA CORNISH, Ph.D. FNAI, FAAS – Endowed Chair and Ohio Research Scholar, Bioemergent Materials, Department of Horticulture and Crop Science, Department of Food, Agricultural and Biological Engineering, Ohio Agricultural Research and Development Center, The Ohio State University

Natural rubber is a strategic raw material essential to the manufacture of 50,000 different rubber and latex products. Until recently, natural rubber has been produced solely from a genetically narrow, single species, the rubber tree, grown in tropical regions. Developed countries import all the natural rubber they require—approximately 1.2 megatons a year by the United States. Dr. Cornish’s disruptive technologies encompass the value chain that underlies sustainable and resilient domestic production of alternate natural rubber, from crop domestication through agronomy and processing, to product manufacturing and validation. Highlights of these developments will be discussed in the context of high-value market opportunities and 100 percent crop consumption.

FATIMA: A European Project on Precision Agriculture with Emphasis on Variable Rate Nitrogen Fertilization

Soil Ecology and Bitechnology Lab Director, Goulandris Natural History Museum, Greece, Adjunct Professor, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Stamatis was born and attended high school in Athens, Greece. He received his B.Sc. degree in 1980 in biology from the University of London, his M.S. in 1983 and Ph.D. in 1986 in soil biology & ecology from the department of Environmental Science and Forestry, SUNY, Syracuse, New York. Upon graduation, he held a postdoc appointment as a research associate in Soil Microbiology with John Doran, Ph.D., (by cooperative agreement between the University of Nebraska-Lincoln and USDAAgricultural Research Service). From 1989–1992 he taught terrestrial ecology and soil microbiology at the University of the Aegean, Greece, while at the same time he established the Soil Ecology and Biotechnology Laboratory at the Goulandris Natural History Museum, Athens, Greece. His early laboratory research concerned mass protein production from earthworms and microalgae. In the 1990s he collaborated with ARS-Lincoln and UC-Santa Cruz for development of soil quality indicators. Since 2000, he works in association with James Schepers, Ph.D., of ARS-Lincoln, on ground-sensor remote sensing technologies and variable-rate nitrogen application systems. Latest accomplishments are the direct funding of two European Union projects on precision nitrogen and water management—HydroSense and FATIMA—while maintaining an adjunct professor status at Nebraska.
