Five factors of soil formation
Parent material, climate, biota (organisms), topography and time interacted to form over 1,100 soils in Minnesota. The different properties of these soils have a big impact on how they are best managed.
Soil orders and suborders in Minnesota
When producers understand the soil they’re working with, they can make better decisions about cropping systems and fertilizer and water management.
- Understand the benefits of soil organic matter (SOM) and how to increase it.
- Learn how SOM affects crop productivity.
- Learn how soil microorganisms contribute to soil health and crop productivity.
- Learn about management practices that increase microbial activity.
The Upper Midwest Tillage Guide is a collaboration between University of Minnesota Extension and North Dakota State University.
- A brief history of tillage and tillage research
Part 1 explores the benefits of tillage from an historical perspective.
- Tillage implements, purpose and ideal use
Part II describes equipment components, depth of tillage and typical residue covers for various tillage implements.
- Reducing tillage intensity
Increased soil structure, organic matter and reduced soil erosion are some of the many benefits of reduced tillage discussed in Part III.
- Economics of tillage
Part IV looks at crop yields and tillage costs of various tillage systems.
Maintaining soil productivity
Soil erosion cuts your profits and reduces productivity by removing a non-renewable resource. Learn how to reduce wind erosion for long-term profitability:
- Why wind erosion is important in Minnesota
- Key factors and impacts of wind erosion
- How to reduce wind erosion

3. Tracks and tires - Learn how to how to manage wheel traffic and properly inflate tires to reduce soil compaction.
2. Soil structure: A natural defense against soil compaction - Learn how soil aggregates create a strong, resilient soil.
4. Proper tire inflation - Learn how to get the best performance out of your tractor tires.
