Research in our lab is a multidisciplinary approach to improving stress physiology of economically important plant species and management of different turfgrass systems to reduce inputs and maximize the environmental, social and economic benefit of turfgrass systems. There are four primary areas of research in our lab:
Improving Stress Physiology of Economically Important Plant Species
Our research in this area focuses on nutrient stress, drought tolerance and winter survival of plants. The research attempts to understand the signal transduction pathways involved in acclimation and de-acclimation to different external stimuli and how plants can be manipulated through nutrient status or through altering hormone signaling within the plants. In addition root morphological changes in response to drought and nutrient stress are also examined.
Plant Competition and Species Composition of Perennial Plant Ecosystems
This research focuses on how different factors such as, wear, disturbance, seed dynamics, root growth dynamics and nutrient availability affect the presence of different species within a perennial plant system. Overseeding, or the introduction of a desirable species into an existing stand, is a common practice in a number of plant systems including athletic fields and golf course putting greens. Our research studies how seed introduction of different species impacts the final species composition of the stand and how it affects the seed bank dynamics. In addition we study how nutrient availability affects rooting and root competition for resources of both phosphorus and nitrogen. The acquisition of nutrients and water by root systems is an important factor in determining the final plant composition of an ecosystem.
Management of Sports Fields without traditional pesticides
This applied research examines the different aspects of how to better manage community sports fields in wake of provincial and community restrictions on traditional agricultural chemistries. The work focuses includes studies into the impact of weeds on sports field safety and how to maximize limited resources to achieve the safest possible sports fields for community use.
Innovation of New Technologies for the Turfgrass Industry
Our research lab works closely with a number of companies to bring new and innovative products. Our research helps improve technologies making them more accessible to turfgrass managers. In addition we act as an independent lab testing products for registration and labeling purposes. In addition to working with companies our research lab also partners with a number of other researcher groups to create applications within the turfgrass industries for their innovations and discoveries.
For more information about our research lab and the people that make it all happen please check out the Canadian Turfgrass Innovation Centre (CTIC) web page and the Guelph Turfgrass Institute (GTI) web page.
Education and Training: Courses I Teach
Associate Diploma in Turfgrass Management
The university of Guelph is a leader for turfgrass management in Canada and throughout the world. The associate diploma in turfgrass management is a two year applied program catering to a number of careers in turfgrass management including, golf course superintendents, municipal parks/grounds managers, and landscape management.
DTM*3000 - Turf Management II
DTM*4300 – Turf Case Studies
Crop, Horticulture, and Turfgrass Science, Plant Science Majors
HORT*2450 – Introduction to Turfgrass Science
PLNT*6400 - Seminar
I have served as the faculty facilitator for this course where graduate students present their research proposal to the department.
PLNT*6230 – Colloquium in Plant Physiology and Biochemistry
This colloquium is offered on a rotational basis based on topic and when I teach this colloquium the focus is on methods in root biology and root research.
Graduate Student Advising
A number of graduate students work on a number of projects within the lab. I am an advocate of multidisciplinary approaches to science so a number of my students are co-advised. Students are encouraged to work independently and learn both science and project management skills. Many opportunities exist to facilitate graduate positions including scholarship programs and industry collaborations and students are encouraged to explore these opportunities.
Outreach and Other Training Courses
Turfgrass Managers Short Course (http://tmsc.open.uoguelph.ca)
The turfgrass manager’s short course is an intensive 4-week course in turfgrass management. I teach turfgrass management focusing on mowing fertility and irrigation philosophy. The focus of my tie with the student concentrates on not only mastery of the material but on improving critical thinking and problem solving skills of the participants.
Sports Turf Management and Maintenance Course (https://www.sportsturfcanada.com/node/43)
This three and a half day program serves as a base education and review for all levels of sports turf managers. The course content was designed by experienced sports turf managers to assure it teaches what the job requires and we then refined the course through the input of course participants create the best learning experience for the participants.
Ontario Turfgrass Symposium
The Ontario turfgrass symposium is an annual turfgrass education conference that caters to all segments of the turfgrass industry. The education is research based and brings in turfgrass scientists from the University of Guelph and throughout North America to communicate the latest information to turfgrass managers.
High School Liaison Activities
The Department of Plant Agriculture and the OAC are committed to plant science education in both basic and applied fields. Our department is actively involved in hosting high school students on campus and creating fun interesting interactive lesson plans that will help students gain interest in the plant sciences and begin to train the next generation of leaders in the area of plant production systems and plant sciences.
For more information about OAC liaison activities contact:
Ontario Agricultural College Liaison Officer
For more information about developing or sharing plant science lesson plans please contact either Karen Nelson or myself at email@example.com
