Autor: Kittima Waithaisong, Agnès Robin, Valentin L'Huillery, Josiane Abadie, François-Xavier Sauvage, Patrick Chemardin, Louis Mareschal, Jean-Pierre Bouillet, Jean-Paul Laclau, José Leonardo Moraes Gonçalves, Claude Plassard

Publikováno v: Environmental Advances, Vol 8, Iss , Pp 100247- (2022)

Eucalyptus is the tree most widely planted in tropical countries to satisfy growing demand for wood products, but high yields require high fertilizer inputs. Introducing N2-fixing trees (NFT), such as Acacia mangium, has been proposed to improve soil

Potential of Bioassays to Assess Consequences of Cultivation of Acacia mangium Trees on Nitrogen Bioavailability to Eucalyptus Trees: Two Case-Studies in Contrasting Tropical Soils

Autor: Kittima Waithaisong, Agnès Robin, Louis Mareschal, Jean-Pierre Bouillet, Jean-Michel Harmand, Bruno Bordron, Jean-Paul Laclau, José Leonardo Moraes Gonçalves, Claude Plassard

Publikováno v: Plants, Vol 12, Iss 4, p 802 (2023)

We hypothesized that the nitrogen-fixing tree Acacia mangium could improve the growth and nitrogen nutrition of non-fixing tree species such as Eucalyptus. We measured the N-mineralization and respiration rates of soils sampled from plots covered wit

Publikováno v: Forest Ecology and Management

Sustainable management of highly productive eucalypt plantations requires the application of fertilizers to balance nutrient exports associated with biomass removal every 6-7 years. Although deep leaching after clear-cutting is an important component

Logging residues promote positive interactions between soil erosion, soil functioning and soil macrofauna diversity in young rubber plantations in Africa

Autor: Louis Mareschal, Jean-Louis Janeau, Marianne Legrand, Frédéric Gay, Aymard Kouakou, Alain Brauman, Antoine Manizan, Jean-Paul Laclau, Thibaut Perron

Soil erosion causes major problems of land degradation in agricultural systems leading to losses of soil fertility. Rubber tree is one of the main tropical perennial crops with about 13 million hectares of plantations worldwide in 2018. In the early

Soil health is defined as the soil's capacity to deliver ecosystem functions within environmental constraints. On tree plantations, clear-cutting and land preparation between two crop cycles cause severe physical disturbances to the soil and seriousl

The determination of the mechanisms and extent of soil mineral weathering can be challenging, and the caveats reside in 1) difficulty identifying minerals that are actually involved in weathering reactions, 2) non-stoichiometric release of cations du
