The belowground communities include a large variety of soil organisms showing highly complex interactions. Among the great diversity of soil biota, plant roots, earthworms, and arbuscular mycorrhizal fungi (AMF) that form a symbiosis with plant roots, are key components. However, only few studies tried to assess the individual or interactive effects of these soil organisms on soil properties and...

Roots, earthworms and mycorrhizae : individual and interactive effects on some chemical, physical and biological properties of soils

Kohler-Milleret, Roxane ; Gobat, Jean-Michel (Dir.) ; Le Bayon, Claire (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2009 ; Th. 2096.

Les communautés des êtres vivants dans le sol incluent une grande variété d’organismes qui sont liés entre eux par des interactions complexes au niveau des chaînes trophiques ou non trophiques. Les organismes du sol sont reconnus pour leurs contributions à un grand nombre de services des écosystèmes. Ils peuvent modifier la structure du sol et son régime hydrique, accroître la...

Soil carbon addition affects plant growth in a species-specific way

Eschen, René ; Müller-Schärer, Heinz ; Schaffner, Urs

1. Restoration of ex-arable land to species-rich habitats has become common practice in Europe as a result of Agri-Environment Regulations. The results, however, are highly variable and often disappointing. Competition from weedy species as a result of high soil inorganic nitrogen levels can negatively affect the establishment and growth of desirable grassland plant species. One method...
