Fonte, Steven J.Quintero, Diana CarolinaVelásquez, ElenaLavelle, Patrick M.[Interactive effects of plants and earthworms on the physical stabilization of soil organic matter in aggregates]Interactive effects of plants and earthworms on the physical stabilization of soil organic matter in aggregates

The response of earthworm communities to farming practices was assessed in 33 farms of the Soummam valley (Algeria). Market gardening was the most intensive practice with frequent tillage (94% farms), application of chemical (94%) and organic (70%) fertilizers and pesticides (70%). Orange tree pl...

Sub-adult individuals of Aporrectodea caliginosa were incubated for 16 weeks under laboratory cultures in a soil treated with 0%, 10% or 50% of a Populus nigra half-decomposed leaves, respectively. Growth was maximum in the 50% organic matter treatment and cocoon production occurred. Average soil...


Zhang, CLanglest, RVelásquez, E.Pando, ABrunet, D.Dai, J.Lavelle, Patrick M.[Cast production and NIR spectra signatures of Aporrectodea caliginosa fed soil with different amounts of half-decomposed Populus nigra litter]Cast production and NIR spectra signatures of Aporrectodea caliginosa fed soil with different amounts of half-decomposed Populus nigra litter

Adding biochar to soils and maintaining high earthworm biomasses are potential ways to increase the fertility of tropical soils and the sustainability of crop production in the spirit of agroecology and ecological engineering. However, a thorough functional assessment of biochar effect on plant g...


Noguera, DRondón, Marco AntonioLaossi, KRHoyos Villegas, V.Lavelle, Patrick M.Carvalho, M.H.C. deBarot, S[Contrasted effect of biochar and earthworms on rice growth and resource allocation in different soils]Contrasted effect of biochar and earthworms on rice growth and resource allocation in different soils

Soil ecosystem engineers are major actors of soil macroaggregation, a process that drives the production of ecosystem services by soils. However, our inability to identify the origins of different types of macroaggregates found in soils is an obstacle to describing and modeling their dynamics and...

Jiménez, J.J.Thomas, R.Fisher, M.Asakawa, N.Decaëns, ThibaudLavelle, Patrick M.Mariani, L[Impacto de los organismos del suelo en la diversidad vegetal y la abundancia: estudio de caso de una especie nativa de lombriz de tierra anécica]Impacto de los organismos del suelo en la diversidad vegetal y la abundancia: estudio de caso de una especie nativa de lombriz de tierra anécica

In this study, we investigated the spatial distribution of an earthworm community together with the heterogeneity of selected soil properties in a gallery forest (GF) of the Colombian Llanos . We performed fine-scale spatial variability by intensively sampling 100 points distributed in the nodes...

Castellanos Suarez, Diana EdithGigon, AgnèsPuga-Freitas, RubenLavelle, Patrick M.Blouin, ManuelVelásquez, Elena[Combined effects of earthworms and IAA-producing rhizobacteria on plant growth and development]Combined effects of earthworms and IAA-producing rhizobacteria on plant growth and development

Tropical soils are particularly vulnerable to fertility losses due to their low capacity to retain organic matter and mineral nutrients. This urges the development of new agricultural practices to manage mineral nutrients and organic matter in a more sustainable way while relying less on fertiliz...
