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.

All,

Our NUE paper (1999) is close to receiving 1700 citations. It is now 6th all-time concerning citations for the entire history of Agronomy Journal (1908 to present). This started with a simple question, that it turns out was important and for which others were interested in the answer as well. This question led to other questions (PUE, KUE, SUE) that have since been addressed as well.

If you have a question that needs to be answered, the time to start is now. It may take years to answer, but years are what you have on your side. I remember being discouraged from completing the AJ 1999-NUE paper, but where time has shown that it was of value to our research society. Certain groups have absolutely no idea how valuable this work is, and do not care. Nonetheless, what we have to do as researchers is to stay true to our responsibility to ask those viable and salient questions. This paper opened the door for other really good questions that are now cited as well (PUE, KUE, SUE). I encourage you to work with your fellow students to ask these types of questions as well and to pursue them with the energy each deserves.

Furthermore, this past week, my total citations eclipsed 14,000. Does anybody really care what this number is? The answer is no, anyway not in our current structure. However, it is a value that time will always hold on to, and that the H-index will record until it too is replaced by a more robust metric that represents productivity in science.

This is just another reminder to ask good questions. Yesterday I mentioned the abstract for the environment paper. This is now included. Having a mathematical value that could holistically communicate environment is the objective. With Jagman on the cusp of leaving OSU, I challenge him and our other senior PhD students to think this through. Yield is an expression of that environment. The question needs to be turned on its head whereby my enviro-metric describes ranges.

If you wait to write, that model does not work. Write it down, whatever it is that you believe is relevant at the time. Complete the review of literature before you have any data. A random compilation of ideas can be sorted out later. There does have to be an objective, but that too can take shape as you move your idea forward. The experimental method that you are accustomed to is a bit different as it has to follow a formal path. However, idea papers like this have no structured rules that have to be followed.

Write, and write often.

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.
