Example Abstract (Agronomy Journal) ASA Abstract

SI Units and conversions (American Society of Agronomy)
SOIL 5112 (Student Abstract)
Our present world population of 7.4 billion people depends on the availability and use of nitrogen (N).  Nitrogen fertilizer is widely used in global cereal production, with the three main cereals being maize, rice, and wheat. Nitrogen Use Efficiency (NUE) is 33% for cereal production in the world, meaning 67% is lost to the environment or sequestered in organic fractions. Present challenges are centered on improving global NUE through the utilization of mid-season sensor based-N management strategies. This emerging field encumbers estimates of final grain yield utilizing estimated mid-season biomass, projected growth rates for the growing-environment and season in question, which ultimately leads to tailored fertilizer N rates.  This approach delivers overnight increases in NUE through customized fertilization rates for each unique set of growing conditions.   The objective of my thesis study is to determine the optimum preplant fertilizer nitrogen (N) rate for maize (Zea mays L.) and sorghum (Sorghum bicolor) in a dryland production environment. Delayed or reduced applications of N are ideal so long as final grain yield is not sacrificed. This approach has the potential to increase NUE and provide a positive economic return to producers.

Since 1991, 85 students have received M.S. or Ph.D degrees in Soil Science at Oklahoma State University working primarily in Precision Agriculture.  These students have gone on to excel in University, Private, and Public settings, and their teamwork at OSU has led to the development of GreenSeeker sensors that are now commercially sold via NTech Industries (www.ntechindustures.com).  The key to the success achieved at OSU can be attributed to the unselfish commitment from each of our students to the development of applied technologies that can be used in both the developed and developing world.  Our students are the central shining fabric of what we are all about. 

Graduate students in our program are required to travel, with the majority of travel tied directly to the extension of improved sensor based nutrient management strategies.  To date, 82 of our students have traveled and worked abroad on a short term (2 week) and long term (1 semester) basis.  Countries where they have worked include Mexico, Argentina, Zimbabwe, China, India, Uzbekistan, Australia, Canada, and the Philippines. We welcome you to apply to our graduate program which has averaged 10 students per year, working as team members within one of the most productive and dynamic precision agriculture projects in the world.
