About the study

This study is located on Treaty 1 territory, at the Ian N. Morrison Research Farm in Carman, Manitoba. There are seven cropping systems with a wide variety of crops grown in rotation. The crops grown vary for each location and are based on common cropping systems in each “eco-zone”.


Determine the best cropping system for the ecozone—the Eastern Prairies, the Parkland Region, and dry/drought areas.

Improve nutrient use efficiency with a “nutrient balance model” for crop input and by exploring soil residual nutrients with contemporary crop rotation sequences.

Enhance system resiliency—the ability to tolerate and/or resist abiotic and biotic stresses or recover rapidly from stress-induced damage—by integrating best management practices (BMPs).

Improve long-term soil health by improving soil fertility and exploring beneficial soil microbiomes.

Experimental design

This study is a randomized complete block design and all rotations are fully phased, meaning all crops are grown each year.

Diversified system

The multiple commodity diversified system is a canola-winter wheat-soybean-canola rotation that uses a “nutrient balance model” to determine fertilizer rates.

Freestyle system

In this system, crop rotation decisions are heavily weighted to current market conditions.

High-risk, high reward

In this innovative system, crops that have great potential but are high risk are integrated with dominant crops. The crops are corn-dry bean-canola-sunflower.

Green manure incorporated system

A green manure is added to enhance soil health while maintaining the yield of the dominant crops. The rotation includes a cereal-legume green manure (Faba/crimson barley), fall rye with a cover crop (faba, 4010 pea-oat), a corn-soy intercrop, and a canola-pea intercrop.

Perennial wheat

In this rotation, perennial wheat kernza is established in the first, second, third, or fourth year.
