The Soybean and Pulse Agronomy Lab focuses on applied soybean, dry bean and pea agronomy and optimization of soybean and pulse cropping systems. The goal of my research program is to study and develop best management practices and cropping systems that optimize agronomy, profitability and sustainability for farmers in Manitoba and western Canada. I also bring leadership in the area of applied science, extension, teaching and integration of those processes.
What is agronomy?
Agronomy is the study of soils and plants, the practice of field crop production, and the management of land and water resources.
- U of Manitoba
Study and develop best management practices for soybean, dry bean and pea cropping systems through agronomic research, extension and training.
The soybean and pulse agronomy research lab was initiated by and remains primarily funded by Manitoba soybean, dry bean and pea farmers through the Manitoba Pulse & Soybean Growers association. Supplementary funding has also been provided by the Province of Manitoba and Government of Canada through the Canadian Agricultural Partnership and Growing Forward II.

Kristen joined the Department of Plant Science in 2016 through a grassroots initiative led by the Manitoba Pulse & Soybean Growers in partnership with the University of Manitoba to increase capacity to conduct applied agronomy research focused on soybeans, dry beans and peas in Manitoba. The inaugural Agronomist-in-Residence initiative also aims to enhance student experiences and prioritize extension.
Since 2017, Kristen has developed and led 14 applied research experiments throughout agro-Manitoba and prioritizes rapid dissemination of results for on-farm adoption. She collaborates with applied research centers and farmers to test agronomic practices in a range of cropping systems. Under her leadership, Kristen’s team has inspired 5 technicians, 5 undergraduates and over 15 high school students in soybean and pulse crop agronomy and Manitoba cropping systems.
Prior to joining the U of M, Kristen was the first Production Specialist and Director of Research & Production with Manitoba Pulse & Soybean Growers from 2013-2016 during the major soybean acreage expansion. Kristen developed the first Research & Production Strategy for the organization which included the Bean Report, field scouting network, targeted research investments, expansion and branding of the On-Farm Network, disease survey and a suite of production resources. She met many farmers, agronomists and industry advisors along the way and maintains a strong connection to the field.
