Ken Olson doesn't dispute that no-till can sequester organic carbon in the soil, or provide numerous other benefits to farmers.

Corn Stover Removal And No-Till: A Balancing Act

No-tillers that follow guidelines can remove some stover from continuous-corn fields and still warm up soils, improve nitrogen efficiency and retain organic matter.

The heavy snowpack covering Iowa's farm fields hides many secrets, including a future this spring that could mean flooding and significant, damaging runoff of Iowa's topsoil and its crucial nutrients.

Determine Residue’s Value Now

When selling residue becomes an option, no-tillers will have to consider the residue needed for soil protection and the cost to replace lost nutrients.

By Mark Moore posted on May 1, 2007 | Posted in Residue Management

Corn residue generates increasing interest as a source of value-added products, most notably ethanol. But before you begin to collect corn stover, it’s important to realize the value of leaving residue for your no-tilled ground. Collecting the stover might offer some no-tillers a great opportunity to pull additional income from their fields; but for others, the value of the residue is greater if it is left on the ground.
