Study raises no-till yield concerns

A study on the global yield impact of no-till farming says it shows promise in dryland areas but may not be the answer to increased yields as predicted elsewhere.

The University of California-Davis led the international research analysis of the conservation agriculture method. A University of Illinois Crop sciences researcher co-authored the study.

They examined more than 600 peer-reviewed studies and found that no-till often leads to yield declines, although it has been promoted worldwide as a way to sustainably meet growing global food demand.

The study is published in the October 22nd journal “Nature.”
