About the webinar

No-till on the Plains and GeoAgro had the pleasure to organize this inaugural webinar for the No-till University. The vision for the No-till University project came about because of the need and a desire to have top-quality information at the fingertips of producers worldwide so that continuous no-tillage (CNT) production will continue to expand and increase in quality. Its initial deployment is being funded by a Conservation Innovation Grant awarded by the USDA NRCS Oklahoma State Office.

In this inaugural Speech, Dr. Rolf Derpsch gives an overview of present issues and opportunities for no-till adoption in the United States.

Currently no-tillage has reached a plateau and in many cases is not sustainable. Under current practices it seems difficult to move the system a step further. This presentation deals with the different aspects that differentiate practices currently being applied in no-tillage technologies and quality continuous no-till. It analyzes the reasons why farmers in the US are using rotational tillage and show why permanent no-till systems with full stubble retention show advantages over the traditional system.

Also, it reviews some examples of poor quality no-till being applied by farmers and will address the necessary steps to be able to move no-tillage to the next level and make it a truly sustainable agricultural system.

The following polls were carried out during the webinar:

It is unavoidable to plow the soil to redistribute P concentrated at the soil surface or to incorporate lime in a NT situation


In a No-tillage system it is good to bale and sell part of the crop residues to have an additional income


To achieve the goal of quality no-tillage the most important thing is to apply a lot of fertilizer


Farmers in the US use rotational tillage because
