Reduced tillage and green manures for sustainable organic cropping systems – TILMAN-ORG

Funding: CORE Organic II Funding Bodies, being partners of the FP7 ERA-Net project CORE Organic II.

Duration: 2011–2014

Project coordinator: Dr. Paul Mäder, Research Institute of Organic Agriculture FiBL, Switzerland

Deputy coordinator: Dr. Christophe David, ISARA, France


The overall goals of the project Reduced tillage and green manures for sustainable organic cropping systems – TILMAN-ORG were  to design improved organic cropping systems with: enhanced productivity and nutrient use efficiency, more efficient weed management and increased biodiversity, but lower carbon footprints. The project ran from 2011 to 2014 and was funded in the framework of CORE Organic II. The contents of this website are not updated.  More ...

The key outcomes of the project are listed below.

TILMAN-ORG: Key results

The results of TILMAN-ORG are encouraging for organic farmers and advisors to apply reduced tillage and green manures. When applying reduced tillage, green manures are a good strategy to control weeds. Overall, yields were not impeded substantially under an adjusted fertilisation regime, and weeds can be controlled. Further research and development is needed to synchronise nutrient supply and demand, to improve the machinery and to adapt a farm-specific reduced tillage system to keep weeds controlled in the long-term.

TILMAN-ORG project flyers

In the first TILMAN-ORG flyer (739.9 KB) the project aims and partners are described.

The second TILMAN-ORG project flyer (7.1 MB) shows how the implementation of  reduced tillage practices in European organic farming systems was addressed by an interdisciplinary team of researchers from 11 European countries.

Article in International Innovation

In the article "Green fingers", the core team of TILMAN-ORG, Drs Paul Mäder, Christophe David and  Julia Cooper, discuss their aims to develop organic farming and conservation agricultural practices through the  TILMAN-ORG project, and what challenges must be overcome.
