Direct seeding mulch-based cropping increases both the activity and the abundance of denitrifier communities in a tropical soil

2009

International audience; This study evaluated the impact of direct seeding mulch-based cropping (DMC), as an alternative to conventional tilling (CT), on a functional community involved in N cycling and emission of greenhouse gas nitrous oxide (N2O). The study was carried out for annual soybean/rice crop rotation in the Highlands of Madagascar. The differences between the two soil management strategies (direct seeding with mulched crop residues versus tillage without incorporation of crop residues) were studied along a fertilization gradient (no fertilizer, organic fertilizer, organic plus mineral fertilizers). The activity and size of the denitrifier community were determined by denitrifica…

Effet d’une toile de paillage naturelle sur une culture de salade - rendement, etat sanitaire et faune du sol

2019

Le projet de stage c'est déroulé dans le cadre du projet PIA3 "Mulch Catalyse" coordonné par Fabrice L. Martin en partenariat avec l'entreprise "Géochanvre F" dirigé par Frédéric Roure. L'entreprise produits des toiles de paillages en fibres naturelles biodégradables dont l'usage permet, entre autres, de limiter la croissance des plantes adventices des cultures, notamment en maraîchage. Le sujet de stage portait sur l'étude de l'effet de plusieurs types de toiles de paillages sur la vie du sol en condition maraîchères, et de les comparer à un sol nue ou couvert de plastique
