Comparison of different tillage systems in organic farming : effect of soil structure and organic matter repartition on soil micro-organisms and thei…

2009

Over the last decades, the surface traditionally ploughed has tended to decrease and replaced by shallow working tillage techniques without soil inversion, i.e., no tillage or reduced tillage with tines or discs. These techniques were mostly developed in conventional farming systems but nowadays they are also developed in organic farming systems. Nevertheless, these tillage techniques could generate crop nutrients deficiencies and a deterioration of soil structure, especially during the first years of their application. As the use of synthetic fertilizers is forbidden in organic farming, a decrease of the soil fertility could be very detrimental for crop growth. Indeed, soil micro-organisms…

Impact du travail du sol sur son fonctionnement biologique

2014

National audience; Les impacts des différentes modalités de travail du sol (labour, semis direct) sur l’environnement et les états du sol, sur la biodiversité ou sur le climat font l’objet de débats parfois passionnés mais souvent trop peu instruits sur les plans scientifique et technique. Que nous enseignent les expérimentations les plus récentes sur ce sujet ? Quelles sont les innovations qui se dessinent à l’heure actuelle ? Cet ouvrage propose une synthèse des connaissances les plus récentes dans ce domaine.
