Cropping systems experimented at Auzeville site

Integrated crops production and pesticides use reduction

Six cropping systems are to be studied at Auzeville site, with the following issue :

How to benefit from natural abiotic and biotic resources through an integrated crop management enabling to limit pests dammages while reducing pesticides impact?

Description of cropping systems to be experimented from 2010 to 2013

* The "Ecophyto 2018" plan is one of the measures proposed by the "Grenelle de l’environnement" in France. It aims at dividing pesticides use by two before 2018.

Each cropping system is repeted 3 times so as to study all the crops of the rotations every year.
