Which conservation tillage management system is right for my farm?

Iowa farmers constantly seek to lower production costs, protect the environment, and conserve natural resources. Adopting conservation practices works hand in hand with paying attention to the basics of production efficiency to achieve all three of these goals.

This post focuses on the first of three in-field conservation practices covered in the manualtillage management.

First things first, let’s define no-tillage and strip-tillage as we have used them in the manual.

No-tillage: Agricultural practice where crops are grown in undisturbed soil and plant residue at the surface.

Strip-tillage: A system with less than one-third of the row width tilled to create a seedbed. The strip- tillage system leaves more than two-thirds of the row width undisturbed between tillage zones.

Together these systems help better protect the soil from erosion by minimize soil surface disturbance.

Tips for success when using these conservation practices

Tillage Residue Management at a Glance

Success with tillage residue management is defined by your ability to meet both row crop production and conservation goals. The table below summarizes tillage management methods for corn and soybean rotations and assigns a relative success rate along with a level of confidence based on published research. There are links to additional resources on pages 58-61 of the manual.
