Gateway to the Future of Agri-Food Knowledge

Industrial application of biotechnology is growing rapidly. The global demand for biotechnology-based products is expected to more than double from $20 billion in 1995 to $50 billion in 2005. Canada is emerging as a significant contributor to this growth.

-Canadian Biotechnology Advisory Committee, Annual Report 1999-2000

There is no denying the impact of the statement above. The rapidly expanding field of agricultural biotechnology in Canada implies great opportunities, as well as great challenges and responsibilities. As the industry grows, not only will there be an increased demand for innovative research, but also the need for well-trained technical staff, scientists and business professionals. The Faculty of Agricultural and Food Sciences at the University of Manitoba is preparing to meet these challenges. On the research side, the Faculty of Agricultural and Food Sciences is poised to play a major role in the development of Manitoba’s own biotechnology sector. With the support of government and industry and collaboration with our research partners, we will take the lead in the study and development of functional foods and nutraceuticals made from crops native to our province. Other research areas continue to emerge that will prove vital to the sustainability of our economy and our environment. We continue to adapt and improve the Faculty’s academic programs to meet the demands of the agri-food industry. Our students receive strong science and business educations, with opportunities for international study, graduate work, and rewarding careers. The success of our students begins with the solid foundation laid by a team of dedicated and talented professors. The Faculty’s instructors are regular winners of teaching awards, nominated both by their own students and by external agencies that wish to recognize these outstanding educators. It is with pleasure that I present the 48th Annual Progress Review of the Faculty of Agricultural and Food Sciences. In the pages that follow, you will find a chronicle of the year’s academic, research and outreach activities. I invite you to read on.

2 ACADEMIC PROGRAMS

Student Exchanges in Europe, US and Mexico Continue The successful European Union exchange project – Exploring Canadian and European Practices and Policy Options for Sustainable Agriculture – continued with five undergraduate students each completing one semester at the Swedish University of Agricultural Sciences (SLU), Uppsala, together with one M.Sc. student enrolled with the Natural Resources Institute also completing one semester at SLU, and one undergraduate student studying at École Nationale Supérieure Agronomique, Montpellier, France for one semester.

The University Industry Liaison Office at the University of Manitoba has helped Dr. Sri Ranjan obtain a provisional patent for the probe. The probe will be a valuable tool for protecting our groundwater resources while helping farmers raise hogs in an environmentally responsible manner.

In another research project, Dr. Sri Ranjan has developed a computer-based Decision Support System that simulates what happens to the nitrates in swine manure when it is applied to soils under different environmental conditions for different crops. The program is designed to help farmers make decisions about how much manure to apply to avoid having it leach beyond the root zone. The program is capable of simulating the environmental impact of different manure application and crop management strategies. The work is ongoing and the goal is to include all of the province’s soil types in the program’s database and eventually make it available over the Internet. The program currently has data for a limited number of soils and crop types.

Dr. Sri Ranjan tests the new hydraulic conductivity probe on the bottom of the Red River. 14 Act allows local governments to adopt district or municipal development plans to designate lands for intensive livestock production operations, and to adopt municipal zoning by-laws that define requirements for their siting and development. As an alternative, intensive livestock operations over a specified size can be identified as a “conditional use” in a “general agriculture zone”, which requires public notice and a hearing to consider the impact of the proposed livestock operation or expansion upon neighbouring land.

By April of 2001, 66 of Manitoba’s 116 RMs had enacted zoning bylaws, which means that 50 RMs had no siting requirements for large livestock facilities. This Governing Growth number will continue to diminish over time as more and more RMs comply with the Planning Act.

Farmers also depend on researchers, such as those in the potato pathology program in the Department of Plant Science, to develop new knowledge.

One approach being used in the potato pathology program is to utilize a computerized Geographical Information System (GIS). GIS allows researchers to compare the environmental conditions of hundreds of Manitoba potato fields, as well as the cultural practices of the individuals farming them, to see how these factors affect disease levels in tubers. Each year, with the permission of growers, Manitoba Crop Insurance provides information on the health of that year’s harvested crops. In 2000, data from approximately 500 fields was collected, and in 2001, 700 fields were analyzed.
