Résumé
[en] Phosphorus management is a key feature in order to achieve sustainability in agro-systems.
In this study, we focussed on the impacts on the soil phosphorus cycle of reduced tillage, cover
crop implementation and crop residues restitution. We investigated soil parameters measured
in three depths (0-10, 10-20 and 20-30 cm) throughout two long term field experiment started
in 2008 and 2011 managed by the experimental farm of Gembloux Agro-Biotech . In addition,
acid ans alkaline phosphatase activities were measured on the 2020 samples in order to evaluate
the biotic pathways of phosphorus mobilisation. Tillage management had the strongest impact
on the available phosphorus content showing a concentration of nutrients and total organic
carbon on surface. Phosphatase activity was stronger in surface in reduced tillage but lower
in depth than conventional tillage. overall our analysis suggest that conservative agricultural
practices promises good leads to reduced the use of mineral P fertilizer in in cultivated Cutanic
Luvisol of Belgium.
