Welcome to Plant and Soil Sciences

We have a great family of faculty, staff, and students who take pride in our commitment to cause positive change in the world!  From the classroom to the field, we are working to develop systems that provide society’s most basic needs in a sustainable way. Crop production, biotechnology, natural resources conservation, and biofuels are just a few of the critical areas of agriculture where we have very strong programs in teaching, research, and extension.

NAPB Announces 2019 NAPB Borlaug Scholarship Awards!

May 7, 2019 – The National Association of Plant Breeders (NAPB) is recognizing 12 outstanding students for the 2019 class of NAPB Borlaug Scholars:


NAPB Borlaug Graduate Scholars

Zaki Afshar, Colorado State University
Jessica Chitwood, University of Florida
Heather Manching, University of Delaware
Stephanie Sjoberg, Washington State University

Daniel Sweeney, Cornell
Caio Canella Vieira, University of Missouri

NAPB Borlaug Undergraduate Scholars

Tannis Anderson, University of Minnesota
Adrienne Blakey, Oklahoma State University
Adam D'Angelo, Rutgers
Elizabeth De Meyer, Cornell
Jordan Knapp-Wilson, University of Arizona
Sarah Marsh, Texas A&M University

The NAPB Borlaug Scholarship awards are given to exceptional students aspiring to a career in the field of Plant Breeding and Genetics and who have a strong desire to contribute to the improvement of the plants that we all depend upon for our daily needs. This is especially critical in this age of continually increasing populations, climate change, and uncertain global food security, all things that Dr. Norman E. Borlaug cared deeply about. Plant Breeding uniquely addresses these challenges through applied research and improving technologies.


Dr. Sergio Abit

Dr. Abit awarded Distinguished Early Career Faculty Award

Dr. Abit was awarded the inaugural Distinguished Early Career Faculty Award at the University Awards Convocation today. This award recognizes faculty members who were awarded tenure within the past three years and have demonstrated a strong potential for continued contributions to the University and his/her profession in the areas of instruction, research, and extension.

Congratulations to Dr. Abit on this well-deserved honor!





The Art and Science of Naming a Wheat Variety

Well, a lot more than you might think, at least when it comes to the Oklahoma State University-bred wheat varieties that ultimately graduate from experimental lines to commercial products.

The OSU Wheat Improvement Team invests an average of 10 to 12 years developing each of the high performing varieties for which the breeding program is known. The same exacting attention is given to naming the tangible fruits of that labor.

In fact, the naming process often begins 1 to 3 years before a variety is released. Yes, it’s that serious.

“As soon as I see an experimental line with commercial potential, the marketing gears begin to turn,” said Brett Carver, OSU wheat breeder.

In late September, OSU released four new hard red winter wheat varieties. As part of their official rollout, experimental lines OK12716, OK13209, OK13621 and OK13625 became Showdown, Green Hammer, Baker’s Ann and Skydance. ...more


2018-2019 Niblack Research Scholars

Oklahoma State University has named 14 students as 2018-19 Niblack Research Scholars, each receiving $8,000 scholarships and the opportunity to conduct research guided by faculty sponsors and graduate student mentors. Adrienne Blakey, Plant and Soil Sciences was named as one of the 14 recipients. ...more


Tyson Ochsner named OSU's 2018 Sarkeys Distinguished Professor Award Recipient

It seems fitting: Oklahoma State University’s Tyson Ochsner, professor and holder of the Sarkeys Distinguished Professorship in Agricultural Science, has been named the 2018 Sarkeys Distinguished Professor Award recipient.

No, they are not the same thing. Presented annually by OSU’s Division of Agricultural Sciences and Natural Resources, the Sarkeys award recognizes outstanding contributions to agriculture through teaching, research or Extension efforts. The award was established by the Sarkeys Foundation in 1980 to honor Elmo Baumann, an agronomist who worked with the foundation after his retirement from OSU.

“I am truly honored to have my name considered, given Dr. Baumann was a distinguished scientist in my own department long before my time,” Ochsner said. “The list of past winners for this award included people who have been my teachers and mentors, and who have been an inspiration to me during my career.” ....more


OSU Soil, Water and Forage Analytical Laboratory provides key services for both rural and urban settings

STILLWATER, Oklahoma – It is impossible to provide an accurate fertilizer recommendation without an accurate soil test, and that is why many Oklahomans in rural and urban settings rely on the Oklahoma State University Soil, Water and Forage Analytical Laboratory.

“Urban or rural, it makes no difference where a person lives,” said Hailin Zhang, laboratory director and OSU Cooperative Extension nutrient management specialist. “Soil tests should be a standard management tool for farmers and homeowners alike.”

It is possible to under- or over-apply fertilizer or animal manure,” Zhang said. “This not only costs money, it also means additional nutrients may enter water supplies and cause problems.”  ...more
