Balancing Steel and Herbicides to
Reduce Resistance:
Farmer Perspective
Craig Fleishman
Cardinal Farms
Minburn, IA
Why Ridge-tillage helps accomplish……
• Soil Health
• Weed Control
• Erosion Control
Conventional Planter with Ridge Cleaners
The Steel Versus Herbicide Balance
in Ridge-Tillage

50%-Herbicide/ 50%-Steel

Buffalo Planter with Sweeps and Guards
Cultivator with Disk Hillers
Two Cultivations
No or Little Herbicide
Non-GMO or Organic Seeds
Rotary Hoe for Weed Control
Make 6” - 8” Ridges Every Year
Furrow or Pivot Irrigation
Very Adaptable to Organic, Longer Rotations
or Integrated-Crop and Livestock Systems
● Wider Rows Needed 30” - 38”

1st Cultivation with
Disk Hillers and
●
Side-Dress NH3
or UAN (Corn Only)
● Corn-Corn-Soybean
Cultivation =
Rotation
Oxygen in Soil = ● Corn-Corn Pre-Clean
Mineralization =
for Blacker Strips
Synergistic Affect ● Corn-Soybean
2nd Cultivation with Strip-Cropping
Ridging Wings;
● Cover Crops
Narrow Sweeps;
in Bean Stubble
No Hillers
● Seed Down Headlands
6” - 8” Ridges
to Oats
Every 1 - 2 Years ● Maintain Grassed
Spot Spray Weed
Hay Headlands
Control for Escapes● RR-Corn and Soybeans

Conventional Planter with Row-Cleaners
0 - 1 Cultivations without Disk Hillers
Broadcast Herbicide
Roundup Ready or Liberty-Link Compatible
Rotary Hoe to Dry-out Ridges
Make 3” - 4” Ridges Every 2 - 3 Years
Chemical Cultivation with Drops
Irrigation Not Needed
Need Good Drainage
Some Potholes “Return to Nature”
Narrow Rows 22” - 30”
