Balancing Steel and Herbicides to Reduce Resistance:Farmer Perspective
Craig FleishmanCardinal Farms
Minburn, IA
Why Ridge-tillage helps accomplish……
• Soil Health• Weed Control• Erosion Control
NEBRASKA STYLE● Lower Rainfall● Buffalo-Till System (Developed by
Fleischer Mfg. Columbus, NE)● 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”
The Steel Versus Herbicide Balance
in Ridge-Tillage Craig Fleishman
The Balance All Depends on the Weather!
Conventional Planter with Ridge Cleaners
Corn and Soybean Strip-Cropping
MINNESOTA STYLE● Higher Rainfall● Econ-O-Till System (Developed by
Jim Johnson Hiniker Comp. Mankato, MN)
● 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”

●Band P&K into the Ridges
●Conventional Planter with Ridge Cleaners
●Band Spray (10”)with Planter
●Rotary Hoe to Dry-out Ridges; Sometimes to break crust
●Early Post-Glyphosate/24DE Burndown
●1st Cultivation with Disk Hillers and Side-Dress NH3or UAN (Corn Only)
●Cultivation = Oxygen in Soil = Mineralization =
Synergistic Affect
●2nd Cultivation with Ridging Wings; Narrow Sweeps; No Hillers
●6” - 8” Ridges Every 1 - 2 Years
●Spot Spray Weed Control for Escapes
●Fence-Row Management
●Corn-Corn-Soybean Rotation
●Corn-Corn Pre-Clean for Blacker Strips
●Corn-Soybean Strip-Cropping
●Cover Crops in Bean Stubble
●Seed Down Headlands to Oats
●Maintain Grassed Hay Headlands
●RR-Corn and Soybeans Treated Like Non-RR
●RTK Makes It Work Better
