Effet des caractéristiques pédologiques et des pratiques agricoles sur la disponibilité du phosphore dans les sols de Wallonie ; Effect of pedological factors and agricultural practices on P biodisponibility in walloon soils

Essential element for plant growth, phosphorus (P) is also a problematic element, due to the limitation of mineral resources but also the environmental problems which can be caused, as eutrophication. For several years, scientific studies have focused on finding other sources of P and making this element more available for plants. However, improving the bioavailability of P involves a better knowledge of the stocks present in Walloon soils but also a better identification of factors governing its mobility for plants and the environment. This thesis focused on knowing P content and behaviour in... Mehr ...
